public final class CopticCalendar
extends AbstractEpagomenalCalendar

The Coptic (Alexandrian) calendar, the liturgical calendar of the Coptic Orthodox Church and a traditional agricultural calendar of Egypt: twelve thirty-day months and a thirteenth epagomenal month, Nasie, of five days, or six in a leap year. It descends from the reformed Egyptian calendar and counts years in the Era of the Martyrs from the AD 284 accession of Diocletian. The months run توت (Thout) through النسيء (Nasie) in Arabic over a seven-day week; a year leaps when it is congruent to three modulo four, the year before a Julian leap year, so a common year is 365 days and a leap year 366, keeping step with the Julian calendar. The epoch is 29 August AD 284 (Julian Day 1824665). Its calendar type is CalendarTypes.COPTIC, and it is paired with UTCTimeDefinition.

Modifier and Type	Method	Description
default DisplayText	getEpochAbbrev()	Gets the short form of the name of the time from the epoch onward, as AD abbreviates Anno Domini; valid when CalendarInfo.isEpochNamed().
default DisplayText	getEpochName()	Gets the name of the time from the epoch onward, as Anno Domini names it in the Gregorian calendar; valid when CalendarInfo.isEpochNamed().
default DisplayText	getPreEpochAbbrev()	Gets the short form of the name of the time before the first day of the calendar, as BC abbreviates Before Christ; valid when CalendarInfo.isEpochNamed().
default DisplayText	getPreEpochName()	Gets the name of the time before the first day of the calendar, as Before Christ names it in the Gregorian calendar; valid when CalendarInfo.isEpochNamed().
default boolean	isEpochNamed()	Tests whether the calendar names the time on either side of its epoch.
default boolean	startsDayAtStartOfClock()	Tests whether this calendar's day begins at the start of the clock -- the zero of the time of day (midnight on a 24-hour clock) -- as opposed to an offset reckoning such as sunset (Hebrew, Islamic) or sunrise.
