The Calendars plugin provides an interface to various calendars
The primary source of this plugin is the book "Calendrical Calculations: The Ultimate Edition" by Edward M. Reingold and Nachum Dershowitz (2018). It contains algorithmic descriptions of dozens of calendars and auxiliary functions, most of which should make their way into this plugin.
This book describes data conversion from and to calendars, using not the commonly used Julian Day number, but an intermediate number called Rata Die (R.D.; easily remembered by the authors' names), days counted from midnight of (proleptic) 1.1. of year 1 AD (Gregorian).
For the user, a simple selection GUI allows choosing which calendars should be displayed in the lower-right screen corner. Some more GUI tabs allow interaction with selected calendars.
A potentially great feature for owners of the book is that most functions from the book are available as scripting functions for the respective calendars. Just call objects by their classnames.
Examples:
core.output(JulianCalendar.isLeap(1700)); core.output(GregorianCalendar.isLeap(1700)); rd=GregorianCalendar.fixedFromGregorian{[2021, 3, 14]);
Take care that some data arguments are internally stored as QVector<int>, and translated to Arrays in ECMAscript. The various calendars may have array lengths of elements, which are not always checked. When a StelLocation argument is used in the internal function, a scripting function is available which allows specifying a location name in format "city, region". This also works with user-specified locations. Time zones only work correctly when specified (in the location database) as full specification like "Europe/Madrid", or in a generic offset spelling like "UTC+04:00" (but not "UT+4"). For use of "calendar locations" that have been used before timezones were introduced, we must work out longitude-dependent UTC offset that must be rounded to the nearest minute.
Occasionally, the time zone support will provide different results between Windows and other operating systems, esp. for historical data. See Qt documentation on QtTimeZone.

| class BahaiAstronomicalCalendar |
Functions for the Bahá´á Astronomical calendar.
The Bahá´í faith, founded in 1844, uses its own calendar, based on the number 19. Until 2015 the calendar was based on the Gregorian calendar, then a more accurate astronomical calendar was decreed. This is the version implemented here.

| class Calendar |
Superclass for all calendars, capable of a multitude of astronomical calculations.
Stellarium uses Julian Day numbers internally, and the conventional approach of using the Gregorian calendar for dates after 1582-10-15. For dates before that, the Julian calendar is used, in the form finalized by Augustus and running unchanged since 8 A.D. Astronomical year counting implies having a year 0, while some calendars adhere to historical counting where 1 B.C. immediately precedes 1 A.D. Some European countries, especially the Protestant countries, delayed the calendar switch well into the 18th century. Other cultures have various other calendar schemes. All calendars implemented here have a numerical vector of integer time elements and may have individual string lists for names of elements like "week days" and "months". If the pattern of weeks and months does not apply, the names may refer to other structural elements.
The most important source used here is: Edward M. Reingold, Nachum Dershowitz: Calendrical Calculations in various editions (1997-2018), referred to as CC. In particular CC:ME=2nd "Millennium edition", CC:UE=4th "Ultimate Edition", with amendments published until January 2022. It describes the Gregorian calendar with year zero, and the Julian without. In this plugin only, we adhere to this convention to finally have all possible variations of dates. It does not use JD directly but a number called Rata Die (RD=JD-1721424.5), a day count starting at midnight of January 1st, 1 AD (Proleptic Gregorian). with functions including "fixed" in their names. Our calendar subclasses can use Calendar::fixedFromJD(jd) / Calendar::jdFromFixed(rd). Other functions with "moment" in their names use double arguments which are RD with fractions of day. Argument names with "_ut" added indicate the RD is given in UT, not local time.
Most functions are static, with names derived from the functions given in Lisp in CC:UE. Most calendars have dates which can be described in lists of integers. Some functions require a StelLocation argument. For accessibility as Stellarium scripting functions, argument order was changed to place the location argument as last and declare it with a default value of the current location, so that it can be used in scripting. Currently, other, non-default StelLocation arguments cannot be used with scripting.

set date from a vector of calendar date elements sorted from the largest to the smallest.
This triggers the jdChanged() signal Note that this must not change the time of day! You must retrieve the time from the current JD before recomputing a new JD. You can also use this with scripting by calling the actual calendars, like GregorianCalendar.setDate([2023, 3, 4]); // This changes the date in the program! MayaLongCountCalendar.setDate([13, 0, 0, 0, 1]); // This changes the date in the program!

Functions for the Chinese calendar (1645 Qing dynasty version)
The Chinese calendar (and related Japanese, Korean and Vietnamese) is a Lunisolar calendar based on astronomical events. The calendar's location for astronomical computations is Beijing. Days begin at midnight. Lunar months begin on the day of New Moon.
Our implementation uses a 5-part QVector<int> {cycle, year, month, leap-month, day}

| class GregorianCalendar |
Functions for the Gregorian calendar.
Stellarium uses Julian Day numbers internally, and the conventional approach of using the Gregorian calendar for dates after 1582-10-15. For dates before that, the Julian calendar is used, in the form finalized by Augustus and running unchanged since 8AD. Some European countries, especially the Protestant countries, delayed the calendar switch well into the 18th century. This implementation strictly follows CC. It provides the "Proleptic Gregorian Calendar" for dates before 1582-10-15. This may be helpful for a better estimate of seasons' beginnings in prehistory. However, also the Gregorian calendar is not perfect, and Neolithic and even earlier dates will still show deviations from the dates well-known from today.

Functions for the Japanese calendar (as derived from the Chinese calendar)
The Japanese calendar is derived from the Chinese calendar (like Korean and Vietnamese). The calendar's location for astronomical computations is Tokyo. Days begin at midnight. Lunar months begin on the day of New Moon. In difference to the CC:UE book, we must introduce function names which replace "chinese" by "japanese", to take the changed location into account or where the culture name is omitted, so that function overrides work.
Our implementation uses the 5-part QVector<int> {cycle, year, month, leap-month, day} inherited from the Chinese calendar. The years are given in Japanese eras.

Functions for the Julian calendar.
Stellarium uses Julian Day numbers internally, and the conventional approach of using the Gregorian calendar for dates after 1582-10-15. For dates before that, the Julian calendar is used, in the form finalized by Augustus and running unchanged since 8AD. Some European countries, especially the Protestant countries, delayed the calendar switch well into the 18th century.

Functions for the Korean calendar (as derived from the Chinese calendar)
The Korean calendar is derived from the Chinese calendar (like Japanese and Vietnamese). The calendar's location for astronomical computations is Seoul. Days begin at midnight. Lunar months begin on the day of New Moon. In difference to the CC:UE book, we must introduce function names which replace "chinese" by "korean" to take the changed location into account.
Our implementation uses the 5-part QVector<int> {cycle, year, month, leap-month, day} inherited from the Chinese calendar. From {cycle, year} the Korean year counted from 2333BCE can be found using koreanYear(cycle, year) which we show in the Calendars output.

staticslot |
Return age of someone born on birthdate on date rd as expressed by the Korean calendar.
This is a mix of Chinese Age and Western calendar, as Koreans consider January 1 as turn of the Year in this calculation (https://www.90daykorean.com/korean-age-all-about-age-in-korea/) Therefore: A new-born is aged 1. Age increases at Gregorian New Year. Returns 0 for dates before birth. According to various sources, the time in the womb is countedc as first year, so it's unclear whether this is strictly correct. A use in scripting would probably be:
|

Functions for the New Hindu calendars described in CC:UE chapter 20.
The new Hindu calendar as given in CC.UE is an astronomical Lunisolar calendar with Solar and Lunar months. The name of a lunar month depends on the solar month that begins during that lunar month. A (Lunar) month is leap and takes the following month’s name when no solar month begins within it. This also may lead to skipped Lunar months. There are two schemes for counting months. In the "amanta" scheme used here months begin and end at New Moon. The other scheme, "purnimanta", has a few peculiarities for counting the leap month, described in CC:UE. In this lunisolar calendar, there are leap months and expunged months. The phase of the moon at sunrise governs day numbers.

| class OldHinduLuniSolarCalendar |
Functions for the Old Hindu Lunisolar calendars described in CC:UE chapter 10.
The old Hindu Lunisolar calendar as given in CC.UE describes the South Indian version where months begin at New Moon (amanta scheme). The name of a lunar month depends on the solar month that begins during that lunar month. A month is leap and takes the following month’s name when no solar month begins within it. The calendar repeats after 180.000 years.

Functions for the Old Hindu Solar calendar described in CC:UE chapter 10.
The old hindu Solar calendar as given in CC.UE describes the one given in the (First) Arya Siddhanta of Aryabhata (499 C.E.), as amended by Lalla (ca. 720-790 C.E.). There are many variations which are not described in CC.UE and therefore not handled in this implementation.

| class TibetanCalendar |
Functions for the Tibetan (Phuglugs) calendar.
The Tibetan Phuglugs/Phug-pa version of the Kalacakra (Wheel of Time) calendar is similar to the Hindu Lunisolar calendars, described as between the arithmetic simplicity of the old Hindu and the astronomical complexity of the modern Hindu. Astronomical events are calculated in local time which may lead to regional deviations. Bhutan, Mongolian and Sherpa calendars are very similar. Months are lunar with lengths of 29 or 30 days. Leap months precede their "ordinary" months, but leap days follow the "ordinary".
Our implementation uses a 5-part QVector<int> {year, month, leap-month, day, leap-day}

Functions for the Vietnamese calendar (as derived from the Chinese calendar)
The Vietnamese calendar is derived from the Chinese calendar (like Japanese and Korean). The calendar's location for astronomical computations is Saigon. Days begin at midnight. Lunar months begin on the day of New Moon. In difference to the CC:UE book, we must introduce function names which replace "chinese" by "vietnamese" to take the changed location into account, or use methods without the culture name.
Our implementation uses the 5-part QVector<int> {cycle, year, month, leap-month, day} inherited from the Chinese calendar. The years are not counted, only named in its 60-year cycle. The book does not indicate whether Solar Terms are used in this calendar and does not provide names. The respective functions have however been been implemented for the calendar's location.
