public final class CopticChronology
Implements the Coptic calendar system, which defines every fourth year as leap, much like the Julian calendar. The year is broken down into 12 months, each 30 days in length. An extra period at the end of the year is either 5 or 6 days in length. In this implementation, it is considered a 13th month.
Year 1 in the Coptic calendar began on August 29, 284 CE (Julian), thus Coptic years do not begin at the same time as Julian years. This chronology is not proleptic, as it does not allow dates before the first Coptic year.
This implementation defines a day as midnight to midnight exactly as per the ISO chronology. Some references indicate that a coptic day starts at sunset on the previous ISO day, but this has not been confirmed and is not implemented.
CopticChronology is thread-safe and immutable.
