This calendar class implements the calendar created by a decree from Julius Caesar in 45 B.C.E. The calendar recognizes a leap year every four years without exception, but in all other respects is the same as the Gregorian calendar, which replaced it in 1582 C.E. Due to the difference in leap-year calculation, the Julian calendar is currently 12 days behind the Gregorian calendar.
