Gregorian

$(ANCHOR _Gregorian) Represents the Gregorian calendar.

Note that this is the Proleptic Gregorian calendar. Most calendars assume that dates before 9/14/1752 were Julian Dates. Julian differs from Gregorian in that leap years occur every 4 years, even on 100 year increments. The Proleptic Gregorian calendar applies the Gregorian leap year rules to dates before 9/14/1752, making the calculation of dates much easier.

Functions

addMonths Time addMonths(Time t, int nMonths, bool truncateDay): Overridden. Returns a new Time with the specified number of months added. If the months are negative, the months are subtracted.
addYears Time addYears(Time t, int nYears): Overridden. Add the specified number of years to the given Time.
calendarType Type calendarType(): Property. Retrieves the GregorianTypes value indicating the language version of the Gregorian.
eras uint[] eras(): Property. Overridden. Retrieves the list of eras in the current calendar.
getDayOfMonth uint getDayOfMonth(Time time): Overridden. Returns the day of the month in the specified Time.
getDayOfWeek DayOfWeek getDayOfWeek(Time time): Overridden. Returns the day of the week in the specified Time.
getDayOfYear uint getDayOfYear(Time time): Overridden. Returns the day of the year in the specified Time.
getDaysInMonth uint getDaysInMonth(uint year, uint month, uint era): Overridden. Returns the number of days in the specified _year and _month of the specified _era.
getDaysInYear uint getDaysInYear(uint year, uint era): Overridden. Returns the number of days in the specified _year of the specified _era.
getEra uint getEra(Time time): Overridden. Returns the era in the specified Time.
getMonth uint getMonth(Time time): Overridden. Returns the month in the specified Time.
getMonthsInYear uint getMonthsInYear(uint year, uint era): Overridden. Returns the number of months in the specified _year of the specified _era.
getYear uint getYear(Time time): Overridden. Returns the year in the specified Time.
id uint id(): Property. Overridden. Retrieves the identifier associated with the current calendar.
isLeapYear bool isLeapYear(uint year, uint era): Overridden. Indicates whether the specified _year in the specified _era is a leap _year.
split void split(Time time, uint year, uint month, uint day, uint doy, uint dow, uint era): Overridden. Get the components of a Time structure using the rules of the calendar. This is useful if you want more than one of the given components. Note that this doesn't handle the time of day, as that is calculated directly from the Time struct.
toTime Time toTime(uint year, uint month, uint day, uint hour, uint minute, uint second, uint millisecond, uint era): Overridden. Returns a Time value set to the specified date and time in the specified _era.
