These are linguistic notes for myself: they are not fully referenced, and there are not many examples. If they help you, great. n.b.: I cannot guarentee the accuracy of these notes.
I had a quick look at:
Here are the Abkhaz alphabet organised phonologicaly. The inventory is that of the standard Abzhywa dialect (other dialects have more consonants). These are the consonants:

For the letter pairs <Ҧ Ԥ> /pʰ/ and <Ҕ Ӷ> /ʁ/, The ones with descenders <Ԥ Ӷ> are the modern standards, but the ones with hooks <Ҧ Ҕ> are still widely used. The ones with descenders <Ԥ Ӷ> are encoded in unicode since version 5.2 (i.e. later than the ones with hooks), and might not render correctly in some devices. (<Ꚋ Ӄ> also existed in earlier Cyrillic orthography of Abkhaz, for mordern <Ҭ Қ>.) There is also a (marginal) phoneme /ʔ/, but I don't know whether it is written or not.
There are two vowel phonemes: /ə/ /a/. There is also a long /aa/, which came from an earlier */ʕa/ or */aʕ/. There are the vowel symbols <Ы ы> for /ə/ and <А а> for /a/, and also <И и У у Е е О о> for other realisations of the vowel phonemes:
(In reality, things with the vowels are more complicated that this; let me read more about it / listen more first.) Stress is contrastive, but not indicated in the script.
This section is primarily about the most common reditions of rimes in Burmese script, and their pronunciation in modern standard Burmese. (Please contact me if you see errors; I am still learning.) I am presenting them in two different ways that I find useful: arrangement based on dictionary order, and arrangement based on their phonology in spoken language. Unicode Burmese font is used here; the most commonly used font in Myanmar, Zawgyi, is encoded differently to Unicode. (On my computer at least,) Firefox renders Burmese script more accurantely than Chrome, so you might want to compare the rendition of Burmese script in different browsers.
Burmese script is follwed by MLC transcription, in italics. The MLC transcription is a transliteration of the written script; like many Brahmic scripts in Southeast Asia, there is considerable distance between the written script and the modern day pronunciation. You might want to have a look at, e.g., the Wikipedia pages on Burmese phonology and Burmese script.
I read about the collation of Burmese script here:
Burmese script is a Brahmic script. Within each orthographic syllable, five types of script elements can be distinguished for the purpose of collation. These script elements largely correlate with the components in a phonological syllable. The collation hierarchy of the script elements is as follows:
For instance, in ကြောင့် kraung. 'because of', က k is the onset, ြ -r- is the onset diacritic, င် -ng is the coda, ော au is the vowel, and ့ . is the tone.
Basicaly follows the Brahmic script order. See the table here. In the table, read from left to right, and then top to bottom row by row. For the two varients of ny, ဉ precedes ည. Ignore the 'independent vowels' symbols for now.
The order is:
Basically any consonant symbol can be used to symbolise a coda by adding the ် a.sat diacritic to signify that it has no phonological vowel. For instance, က is ka., while က် is -k. They have the same order as the onset consonant symbols. Another way to symbolise a coda is using stacked consonant symbols: the normal consonant symbol is the coda, and the consonant symbol placed underneath is the onset of the following syllable. For instance, in မန္တလေး manta.lei: 'Mandaley' (the second city of Burma), န္တ n and t are stacked together; န n is the coda, and the တ t underneath it is the onset of the following syllable (in this case, /t/ becomes voiced /d/). The stacked consonants are collated in the same way as a normal consonant symbols.
Some of the orthographic vowel symbols convey information more than just the phonological vowel. For their phonological values, see the rime table below. The following is the collation order of the orthographic vowel symbols; the vowel symbols are here placed around the zero onset symbol အ. The vowel symbol for a has two forms: the long form ါ and the short form ာ. The short form ာ is the default form; the long form ါ is used after ခ hk, ဂ g, ဒ d, ပ p, and ဝ w, to avoid them looking like other consonant symbols if they are followed by the short form ာ. The long form ါ is here accompanied by the onset ဝ w instead of the zero onset symbol အ. The vowel transcription is that of the orthographic vowel when it is not followed by a coda symbol.
The collation order is as follows:
The following table presents the commonly encountered rimes in Burmese script. In each section the rimes of one or a pair of related vowel symbols are displayed. In the first one or two rows are rimes with no tone symbols, the following row are rimes with a ့ tone symbol, and the following row are rimes with a း tone symbol. (အော် (ဪ) au is put in its own row.) Each column are rimes with different coda symbols, starting with the first column with no coda symbol. For dictionary collation order, you need to read from top to bottom, and then from left to right column by column, because the coda symbol has higher priority than the vowel symbol in collation. The zero/ʔ onset symbol အ is used for the onset. Burmese script is followed by transcription in the same cell, and then its phonological form in the cell below. See also the notes following the table. (An online spreadsheet of this is also available here.)

|အွန်း wan:||အွမ်း wam:|
|[wáN] / [ʔʊ́N]||[wáN] / [ʔʊ́N]|
In Upper Burma/Mandaley, the pronunciation is [waʔ] / [waN], while in Lower Burma/Yangon, the pronunciation is [ʊʔ] / [ʊN], and apparently this has merged into [ɪʔ] / [ɪN] for some people middle aged and younger. Both the Upper and Lower Burmese pronunciations of these are considered standard.
The following are the rimes orgnised phonologically. The onset symbol used is the zero/glottal stop onset အ, or ဝ w when followed by the long form ါ a. Also read the section above for further explanations (e.g. how syllables can be reduced).

I read through this:
I read parts of these:
In Georgian, the inventories of case and personal affixes that can be used to mark core grammatical relations is small. Nonetheless, the same markers are used in different ways, based on the verb class, and also the tense-aspect-mood of the verb for some verb classes. With these complex patterns, and some other morphosyntactic behaviours, different linguistics have been defining/arguing for different mappings between the arguments and the grammatical relations based on different morphosyntactic criteria.
Verb classes. The verbs are commonly divided into four classes. (Some linguists make finer distinctions.) I will simply call them Classes I, II, III, and IV. Prototypically:
There are many cases within each class that deviates from these transitivity prototypes. These verb classes are also characterised by other verbal morphologies, most of which are not discussed here.
Tense-aspect-mood. Each paradigm of tense-aspect-mood is traditionally called in English 'screeve' (from მწკრივი mts'k'rivi 'row'). The screeves can be divided into three series (the labels of the individual screeves often differ slightly in different discriptions:
Core cases. There are three core cases, they are usually called 'nominative', 'ergative', and 'dative'. Their forms vary depending on whether the noun/adjective stem they are attached to ends in a consonant or a vowel.
There are some class IV verbs of which the stimulus (the "object") is marked with a genitive case (noun: -is/-s, stems ending in -a or -e usually have -a/-e deleted and take -is; adjective: -i/-∅), instead of the usual nominative case. However, one line of thought is that since these genitive-marked nominals are not marked with a core case, nor cross-referenced, these nominals are oblique. These cases are not discussed further here.
There are three case marking patterns (-თვის -tvis below is a postposition that governs the genitive case):
|Case pattern ↓||subject||direct object||indirect object|
These three case marking patterns are used with the following verb classes/screeves:
|Verb ↓ | Case ↘ | TAM →||Series I||Series II||Series III|
With case pattern C, there is also Harris (1981)'s opinion that pattern C is a derivative of pattern B, and in pattern C, the DAT-marked nominal is the indirect object, the NOM-marked nominal the subject, and the tvis nominal an oblique object. The derivation from the normal pattern B is as follow: i) the original subject underwent 'inversion', i.e. demotion to indirect object, and hence marked with DAT; ii) the original indirect object becomes an oblique, marked with -tvis; and iii) since there is now no subject, 'unaccusativity' is activated, i.e. the original direct object is promoted to subject, and hence this nominal is marked with NOM. Please see Harris (1981) for her arguments and exact wording. One fact that makes this account for pattern C attractive is that the case marking aligns with the cross-referencing: i) the NOM-marked nominal, traditionally regarded as the direct object, is now regarded as the subject, and it aligns with set I cross-referencing on the verb, which is usually used for subjects; ii) the DAT-marked nominal, traditionally regarded as the subject, is now regarded as the indirect object, and it aligns with the set II cross-referencing, which is usually used for objects; iii) the tvis-marked nominal, traditionally regarded as the indirect object, is now regarded as an oblique, and this correctly matches the fact that this tvis-marked nominal is not cross-referenced. This set of operations occur in TAM series III for verb classes I and III, and in verb class IV. (She also had to formulate that these do not occur twice for class IV verbs in series III.)
Nonetheless, the world is not perfect, and there is one trait that suggests that synchronically, in some ways speakers view the DAT-marked nominal in pattern C as the subject: for third person references, plural subject references can be cross-rerenced by a plural suffix, whereas objects are never cross-referenced as plural; in pattern C, when both arguments are third person, it is the DAT-nominal that can have its plurality cross-referenced by a plural suffix -თ -t, while the NOM-nominal cannot.
Harris' account of the DAT/NOM/-tvis nominal in pattern C being IO/SUB/oblique is at least diachronically correct, while the traditional account of the DAT/NOM/-tvis nominal being SUB/DO/IO is also not without reason. Here I will simply acknowledge that things don't line up nicely, and, when dealing with pattern C, simply call them the DAT-relation/NOM-relation/tvis-relation. (While for patterns A and B, I'll use the terms SUB/DO/IO as usual.)
Cross-referencing. There are two sets of verbal cross-referencing affixes in Georgian (an agreeing nominal does not need to occur): Set I and Set II. Set I is used for subjects. Set II is used for objects, with separate affixes for direct and indirect objects for third person. For case pattern C, Set I is used for the NOM-relation, and set II (indirect object) is used for the DAT-relation. In some verb forms, an auxiliary verb is used in place of a normal set I affix; this auxiliary verb is laregly identical in form as the copula, which itself contains set I affixes. An example is მ-ი-ყვარ-ხარ m-i-q'var-xar 'I love you', where 'I' is cross-referenced with a set II m-, and 'you' is cross-referenced by the auxiliary -xar, identical in form to the copular ხარ xar 'you (sg) are'.
|Auxiliary (Set I)||singular||plural|
The third person allomorphs are morphologically conditioned; it depends on the verb class and screeve. The second person ხ- x- is rare: a) in the present indicative copulas ხარ xar 'you(sg) are' and ხართ xart 'you(pl) are'; b) in the motion verb in the future and aorist series (-თ -t in the following indicates plural subjects): future მო-ხ-ვალ-(თ) mo-x-val(-t) 'you will come', conditional მო-ხ-ვიდ-ოდ-ი(-თ) mo-x-vid-od-i(-t), future subjunctive მო-ხ-ვიდ-ოდ-ე(-თ) mo-x-vid-od-e(-t); aorist მო-ხ-ვედ-ი(-თ) mo-x-ved-i(-t) 'you came', aorist subjunctive (optative) მო-ხ-ვიდ-ე(-თ) mo-x-vid-e(-t). (The preverb მო- mo- can be substituted by other preverbs, e.g. მო-ხ-ვალ mi-x-val 'you will go'.)
|3rd person direct object||∅-||∅-|
|3rd person indirect object||∅-/ს-/ჰ-||∅-/ს-/ჰ-[...](-თ)|
As for the set II third person indirect object affixes: a) ს- s- in front of ც- წ- ძ- ჩ- ჭ- ჯ- თ- ტ- დ- | ts- ts'- dz- tš- tš'- dž- t- t'- d- (all the coronal plosives and affricates); b) ჰ- h- in front of ქ- კ- გ- ყ- | k- k'- g- q'- (all the dorsal plosives) or პ- p'-; and c) ∅ elsewhere. (One line of thinking is that) third person objects never take the plural suffix -თ -t; nonetheless, in case marking pattern C, the DAT-relation is now viewed as the subject, and the corresponding set II third person affix can take the plural suffix -თ -t if the NOM-relation is also third person.
A verb must have a set I affix. If the relation cross-referenced by a set II affix is empty, it is cross-referenced as 3SG direct object, i.e. ∅, by default. These prefixes and suffixes occur at the outer-most periphery of the verb, with the exception that preverbs can exist in front of a cross-reference prefix.
Combining cross-referencing affixes. There is a constraint that at most one non-zero prefix and one non-zero suffix can occur (the internal structure of the copula-like auxiliaries does not count). When more than one is logically needed in the prefix or suffix slot, there is a hierarchy as to which one is kept and which one is deleted (in the list below, > signifies 'has precedence over'):
For prefixes, see below for what happens when there is a 2SG direct object and 3SG indirect object. For the suffixes, it can be reworded like this: any plural suffix has precedence over the plural suffix -თ -t or a singular suffix.
These deletion rules can create two homonym sets, e.g. გმალავთ gmalavt 'we hide you(sg)', 'I hide you(pl)', 's/he hides you(pl)', or 'we hid you(pl)'; გმალავენ gmalaven 'they hide you(sg)' or 'they hide you(pl)'. In the table below, მალ mal is the verb root 'hide', and -ავ -av is a 'thematic suffix' (which is used primarily in the present/future series; in this case the verbs are in present indicative). Set I indexes the subject, and Set II the object, so, for instance, Set I 2SG and Set II 1sg მმალავ mmalav means 'You(sg) hide me'.
|Set I → | Set II ↓||1SG||2SG||3SG||1PL||2PL||3PL|
Two more comments need to be made. Reflexivation is indicated by the noun თავი tavi 'head', sometimes preceded by a possessive pronoun, e.g. ჩემი თავი tšemi tavi 'myself' (3SG reflexive is თავისი თავი tavisi tavi). This reflexive nominal is cross-referenced as third person (and hence the combinations of first person–first person and second person–second person do not feature in the table above). For instance, ჩემს თავს ვ-ა-ქ-ებ tšem-s tav-s v-a-k-eb (my-DAT head-DAT 1SG-NV-praise-TS) 'I praise myself'. Often, subjective version is used (ი- i- in the following example), in which case the possessive phrase is not used, e.g. თავს მო-ვ-ი-კლ-ავ tav-s mo-v-i-k'l-av (head-DAT PV-1-SV-kill-TS) 'I shall kill myself'.
We have seen above that there cannot be more than one non-zero cross-reference prefix. When there are a first or second person direct object and an indirect object, a more drastic approach is used than simply deleting one of the object prefixes: the direct object nominal is changed to თავი tavi 'head' preceded by a first or second person possessive adjective, and it is cross-referenced on the verb as third person, i.e. zero. For instance, შენ-ს თავ-ს მ-ა-ძლ-ევ-ენ šen-s tav-s m-a-dzl-ev-en (your-DAT head-DAT 1SG-NV-give-TS-3PL 'they give you(r head) to me'.
The following is a relatively non-technical description of the Traditional Chinese Calendar. This is compiled from information gathered from various webpages, especially English and Chinese Wikipedia pages.
Nowadays, the Western Gregorian Calendar is used by default in the various Chinese societies. However, the dates of traditional festivals like Chinese New Year and Mid-Autumn Festival are still calculated using the Traditional Chinese Calendar. The rules of the Chinese Calendar have changed over the centuries; this article is only talking about how the Chinese Calendar is calculated nowadays.
In this article, Traditional Chinese Characters are followed by Cantonese Jyutping before slash, and Mandarin Pinyin after slash.
Traditionally, a day is divided into twelve time sections. One Chinese time section lasts for two Western hours. Nowadays, the Western convention of dividing a day into twenty-four hours is followed in Chinese societies. Chinese astronomists have always considered midnight as the beginning of a day. However, for many Chinese astrologists, the beginning of the day is the beginning of the rat time section (子時 zi2 si4 / zǐ shí), which starts one Western hour before midnight. The rat time section lasts from 23:00 till the end of 00:59. For many Chinese astrologists, the rat time section is the first time section of the day. For Chinese astronomists, the rat time section is then a time section which straddles two days. Due to this difference in the interpretation of when a day starts, some people begin their ceremonies/celebrations for, e.g., new years at midnight, while other people begin theirs one Western hour before midnight.
Significant dates for the calculation of the Chinese calendar, e.g. the first day of the month, are calculated based on particular lunar or solar moments occuring during those dates, and the dates are demarcated by 00:00 in UTC+8, the time zone currently used by PRC and ROC.
The month is based on the lunar cycle. The first day of a month is the day that contains the moment of new moon. (New moon is when the moon is least visible; the moon is at the same ecliptic longitude, or "sky longitude", as the sun.) The time between two new moons varies between 29.18 and 29.93 days (due to the orbit/gravity differences between the moon, earth, and sun). Each month in the Chinese Calendar is 29 or 30 days long.
The first ten dates in a month in the Chinese calendar are called 初一 (co1 jat1 / chū yī [first one]), 初二 (co1 ji6 / chū èr [first two])... till 初十 (co1 sap6 / chū shí [first ten]). The rest of the dates in a month are normal numerals: 十一 (sap6 jat1 / shí yī [ten one]) 'eleven', 十二 (sap6 ji6 / shí èr [ten two]) 'twelve', 十三 (sap6 saam1 / shí sān [ten three]) 'thirteen'... 十九 (sap6 gau2 / shí jiǔ [ten nine]) 'nineteen', 二十 (ji6 sap6 / èr shí [two ten]) 'twenty', 二十一 (ji6 sap6 jat1 / èr shí yī [two ten one]) 'twenty-one'... till 二十九 (ji6 sap6 gau2 / èr shí jiǔ [two ten nine]) 'twenty-nine' or 三十 (saam1 sap6 / sān shí [three ten]) 'thirty'. In Cantonese (and many other Sinitic languages), the first two syllables in 二十一 (ji6 sap6 jat1 [two ten one]) 'twenty-one' to 二十九 (ji6 sap6 gau2 [two ten nine]) 'twenty-nine' are often contracted to 廿 (Cantonese jaa6), e.g. 廿一 (jaa6 jat1 [twenty one]), 廿四 (jaa6 sei3 [twenty four]).
Other than the normal date names, there are twenty four special date names in a year. These are the solar terms (節氣 zit3 hei3 / jié qì), corresponding with each 15° along the ecliptic (position of the earth in relation to the sun), starting fron the Spring Equinox. Every second solar term is a zodiac point (中氣 zung1 hei3 / zhōng qì; every 30° from the Spring Equinox). Zodiac points are used for the calculation of leap months (see below).
The First Month of a year is called 正月 (zing1 jyut6 / zhēng yuè; notice that 正 in 正月 is not pronounced zing3 / zhèng). The Second to Twelfth Months are simply called 二月 (ji6 jyut6 / èr yuè [two month]), 三月 (saam1 jyut6 / sān yuè [three month]) etc. until 十一月 (sap6 jat1 jyut6 / shí yī yuè [ten one month]) and 十二月 (sap6 ji6 jyut6 / shí èr yuè [ten two month]). The last two months are also called 冬月 (dung1 jyut6 / dōng yuè [winter month]) and 臘月 (laap6 jyut6 / là yuè [meat_cure month]) respectively. In English I call them 'First Month', 'Second Month' etc. till 'Eleventh Month' and 'Twelfth Month'. A leap month (see below) is called 閏[N]月 (jeon6 [N] jyut6 / rùn [N] yuè [leap [N] month]), with [N] being the number/name of the preceding month, e.g. 閏七月 (jeon6 cat1 jyut6 / rùn qī yuè [leap seven month]) 'Leap Seventh Month' comes after 七月 (cat1 jyut6 / qī yuè [seven month]) 'Seventh Month', and before 八月 (baat3 jyut6 / bā yuè [eight month]) 'Eighth Month'.
(Some people say that 臘月 (laap6 jyut6 / là yuè [meat_cure month]) refers specifically to the last month of the year. In case of an (extraordinarily rare) Leap Twelfth Month (see below), the regular Twelfth Month should be called 十二月 (sap6 ji6 jyut6 / shí èr yuè [ten two month]), while the Leap Twelfth Month should be called 臘月 (laap6 jyut6 / là yuè [meat_cure month]) or 閏十二月 (jeon6 sap6 ji6 jyut6 / rùn shí èr yuè [leap ten two month]). *閏臘月 (jeon6 laap6 jyut6 / rùn là yuè [leap meat_cure month]) is hence an anomaly.)
Twelve lunar months add up to about 354.47 days. On the other hand, one solar year is about 365.24 days. Leap months are added to the Chinese calendar from time to time to make the years catch up with the solar cycle. In other words, a leap month is added in certain years so that the months are roughly in sync with the seasons. In normal circumstances, the correspondence between Western and Chinese Calendar dates repeates every 19 years (Metonic cycle; moon phases repeats every 19 solar years). For instance, a person's birthday according to the Western and Chinese calendars most usually fall on the same day on their 19th, 38th, 57th etc. birthday. Within each 19-Chinese-year cycle are 7 leap months, with each year having at most one leap month (i.e. each year can have 12 or 13 months). In each decade, there are 3 or 4 years with a leap month. Years with a leap month are 2 to 3 years apart. A normal Chinese year has around 354 days, while a Chinese year with a leap month has around 384 days.
A solar year is dissected by 12 zodiac points (中氣 zung1 hei3 / zhōng qì). Starting from the March Equinox (Northern Spring Equinox; i.e. the point when the sun is right above the equator, and gradually moving north towards the Tropics of Cancer), each 30˚ on the ecliptic (the earth moves 30° in relation to the sun) is a zodiac point. The Chinese zodiac points fall sometime between the 18th and 24th (inclusive) of each Western month. Already familiar to most Western readers are the two equinoxes and the two solstices. The twelve zodiac points make a full 360°. The 12 zodiac points are (the actual dates can be ± 1 day from the ones listed below):
The zodiac point dates are roughly the same every year according to the Western Calendar, as the Western Gregorian calendar is purely solar. On the other hand, the zodiac point dates are different every year according to the Chinese Calendar, because the zodiac points are based on the solar cycle, whereas the months are based on lunar cycles, and the solar and lunar cycles do not match. The one fixed rule is that the Eleventh Month is the month with Winter Solstice in it. In a normal 12-month year, usually each month has one zodiac point in it.
The earth's orbit is not a perfect circle. During the Northern Winter, the earth is relatively close to the sun, and the earth travels faster. Around the December Solstice, the number of days between zodiac points are 29 or 30 days. The opposite is true in the Summer. Around the June Solstice, the number of days between zodiac points are 31 or 32 days.
In the Chinese calendar, if there are twelve new moons between two (Northern) Winter Solstices, then there is no leap month in that period. If there are thirteen new moons, then there is one leap month in that period. The leap month is the first month after the Winter Solstice that contains no Chinese zodiac point. In other words, this lunar month, from the day that contains a new moon, to the day before the day that contains the following new moon, fits within a 30° bracket on the ecliptic between two zodiac points. (Very occationally, there are two months with no zodiac points between two Winter Solstices; only the first month is called the Leap [N] Month, with N being the number/name of the preceding month. The second month is simply called the [N+1] Month as usual.)
Take the leap month in 2023 as an example. Between Winter Solstice 2022 and Winter Solstice 2023, there are 13 new moons. A leap month is needed in between. One observes that in (Gregorian) 2023 (UTC+8):
The Chinese month that corresponds to February 20 – March 21 is a normal month, containing the zodiac point of Spring Equinox. Two Chinese months later, the month that corresponds to April 20 – May 18 is also a normal month, containing the zodiac point of Grain Rain. However, the month in between, March 22 – April 19, contains no zodiac point. (This month has 29 days, and there are 30 days between Spring Equinox and Grain Rain.) This is the first month without a zodiac point after Winter Solstice 2022. This Chinese month is hence a leap month. This leap month is called the Leap Second (2nd) Month, as the preceding month is the Second Month (third full month after the Winter Solstice).
By designating a month without zodiac point as a leap month, the default alignments between the twelve zodiac points and the twelve normal months are usually maintained. The Eleventh Month is the month with Winter Solstice. (This alignment trumps other alignments when there is a conflict.) The preceding example shows the usual alignment of the Second Month with Spring Equinox and the Third Month with Grain Rain. Summer Solstice is usually in the Fifth Month, and Autumn Equinox is usually in the Eighth Month.
As mentioned above, because the time between zodiac points are longer in the Northern Summer, leap months usually occur during the Summer. (A month is 29 or 30 days long, and the zodiac points are 31 or 32 days apart during the Summer.) Leap months during the Northern Winter are extraordinarily rare. The next Leap Ninth Month will be in 2109, Leap Tenth Month in 2166, Leap Eleventh Month in 2033 (see below), Leap Twelfth Month in 3358, and Leap First Month in 2262.
Leap months with 29 days are more common. (30-day months are harder to fit between zodiac points.) In the 20th century, there were 25 leap months with 29 days, and 12 leap months with 30 days. The figures given above for the rare Winter leap months are for leap months with 29 days. For 30-day leap months, the next Leap Ninth Month will be in 2576, Leap Tenth Month in 5191, Leap Eleventh Month in 6402, Leap Twelfth month in 8425, and Leap First Month in 9982.
Traditionally, years are named using the [A][B]年 (nin4 / nián [year]) formula. [A] is the "heavenly stem": a set of ten monosyllabic names, in a fixed order. The ten heavenly stems correspond with the five elements of wood, fire, earth, metal, and water, and the yang and yin versions of each of these. [B] is the "earthly branch": a set of twelve monosyllabic names, in a fixed order. The twelve earthly branches correspond with the twelve animals of the Chinese zodiac signs. With each new year, [A] and [B] roll over to the next name in the set. This creates a 60-year cycle, after which the names are repeated in the same order. See this article on the Sexagenary cycle.
These days, most commonly used is the Western year numbering system, e.g. 2022 is 二零二二年 (ji6 ling4 ji6 ji6 nin4 / èr líng èr èr nián [two zero two two year]). In ROC, the era name 民國 (man4 gwok3 / mín guó [republic]) is also used, with 2022 being ROC Year 111 民國一百一十一年 (man4gwok3 jat1 baak3 jat1 sap6 jat1 nin4 / mínguó yī bǎi yī shí yī nián [republic one hundred one ten one year]). These are names of years according to the Western calendar. However, people may use these year numberings for the Traditional Chinese years as well, as these numberings are easier for people to comprehend than the traditional names, e.g. 壬寅年 (jam4 jan4 nin4 / rén yín nián) 'yang-water tiger year' for the Chinese year that began in Gregorian February 1 2022.
With the Eleventh Month being the month containing the (Northern) Winter Solstice, the Chinese New Year (First Day of the First Month) is thus the second new moon after the Winter Solstice. (Unless there is the extraordinarily rare Leap Eleventh or Leap Twelfth Month, then the New Year is the third new moon after the Winter Solstice.) In Western Calendar, the Chinese New Year occurs between January 21 and February 20. (This corresponds roughly to Aquarius in Western astrology, which is approximately January 20 to February 18.)
PRC and ROC calculate the moon and sun positions based on UTC+8 / 120°E. On the other hand, Vietnam makes its calculations based on UTC+7 / 105°E. Occationally the Vietnamese New Year is one day earlier than the Chinese New Year, because the moment of new moon is 23:xx in Vietnamese time zone, and 00:xx the following day in Chinese time zone. A similar phenomenon occurs in Korea and the Ryukyus, as they make their calculations based on UTC+9 / 135°E. Hence the Korean and Ryukyuan New Years are sometimes one day later than the Chinese New Year.
Tibetans and Mongols have a similar lunisolar calendar as the Chinese Calendar. There is sometimes a one-day difference between the Tibetan/Mongol New Year and the Chinese New Year. Sometimes there is a one-month difference, due to the differences in how the leap month is calculated.

In the past, some subtle differences between the current and superseded versions of the calendar rules were not widely understood. People were applying different versions of the rules, causing differing opinions on when the leap month in 2033 will occur. Among other problems, this affects the electronic conversion between Western and Chinese dates. This problem has largely been resolved in software built since the 1990s, but in all likelihood there will be a very small number of rogue software causing trouble in 2033.
The second half of Chinese Year 2033 is a highly abnormal period when the new moons and the zodiac points often occur on the same dates. This has caused there to be three (!) months without zodiac points in the seven months after the Seventh Month 2033 and before the Second Month 2034. These three months are all potential leap months: A) the month after the Seventh Month 2033; B) the fourth month after that; and C) the second month after that (i.e. the month before the Second Month 2034). It is now clear to most people that it is month B that should be the leap month, as it is the first such month after Winter Solstice 2033 (and there are 13 new moons between Winter Solstice 2033 and Winter Solstice 2034). Month B is called the Leap Eleventh Month of 2033. The other months are "fake leap months", i.e. months that lack a zodiac point, but are not called a leap month. Month A in 2033 is disqualified as there are only twelve new moons between Winter Solstice 2032 and Winter Solstice 2033, and no leap month can occur during this period. Month A is called the Eighth Month of 2033. Month C in 2034 is disqualified, because there is already another month with no zodiac point (Month B) between it and the preceding Winter Solstice. Month C is called the First month of 2034.
Having two months with no zodiac points close to each other is very rare, let alone three. As discussed above, having such months in Winter is extraordinarily rare, and there are two of them during this Winter. The failure of the Eighth Month 2033 to become a leap month has caused the three zodiac points of Autumn Equinox, Frost Descent, and Minor Snow to fall in the Ninth, Tenth, and Eleventh Months instead of the Eighth, Ninth, and Tenth Months. The failure of the First Month 2034 to become a leap month has caused the zodiac point of Rain Water to fall in the Twelfth Month instead of the First Month. (The normal Eleventh and Twelfth Months then have two zodiac points each.) These are charted in this table.
In Japan, a total shift to the Western Gregorian calendar was made on (Western) New Year's day in 1873. Festivals are no longer observed according to the old lunisolar calendar. (Except the Ryukyus, which was not fully annexed by Japan until 1879. Some festivities there are still observed according to the old lunisolar calendar.) Despite having fallen into obscurity, the old Japanese lunisolar calendar is still kept track by some people. They are still using the pre-1873 Japanese rules for calculating the leap months. When there is a problem, there is no longer an authority to clarify or change the rules.
In the old Japanese rules, the Autumn Equinox must be in the Eighth Month. In 2033, there are three months separating the Fifth Month (Summer Solstice) and the Eighth Month (Autumn Equinox); there is only one month separating the Eighth Month (Autumn Equinox) and the Eleventh Month (Winter Solstice); and there are again three months separating the Eleventh Month 2033 (Winter Solstice) and the Second Month 2034 (Spring Equinox). People have different opinions on which month(s) should be the leap month(s), and what to do with the one month between the Eighth and the Eleventh month. (Cf. the current Chinese rules only fixate the Eleventh Month to the Winter Solstice, and are flexible with the other zodiac points.)
