ExceptionCondition
ArgumentOutOfRangeException

year is outside the range supported by the calendar.

-or-

era is outside the range supported by the calendar.

Unlike the Gregorian calendar, the Julian calendar defines a leap year as a year that is evenly divisible by four with no exceptions. Therefore, the calendar is inaccurate by one day every 128 years. For example, the year 1999 was not a leap year, but the year 2000 was. A common year has 365 days and a leap year has 366 days.

The following example calls IsLeapYear for five years in each of the eras.
