Remarks

In 45 B.C., Julius Caesar ordered a calendar reform, which resulted in the calendar called the Julian calendar. The Julian calendar is the predecessor of the Gregorian calendar.

The JulianCalendar class recognizes only the current era.

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. A common year has 365 days and a leap year has 366 days.

Like the Gregorian calendar, the Julian calendar has 12 months with 28 to 31 days each: January (31 days), February (28 or 29 days), March (31 days), April (30 days), May (31 days), June (30 days), July (31 days), August (31 days), September (30 days), October (31 days), November (30 days), and December (31 days). February has 29 days during leap years and 28 during common years.

The date January 1, 2001 A.D. in the Gregorian calendar is equivalent to the 19th day of December in the year 2000 A.D. in the Julian calendar.

Currently, the JulianCalendar is not used by any of the cultures supported by the CultureInfo class; therefore, this class can only be used to calculate dates in the Julian calendar.

Each CultureInfo supports a set of calendars. The Calendar property returns the default calendar for the culture, and the OptionalCalendars property returns an array containing all the calendars supported by the culture. To change the calendar used by a CultureInfo, set the Calendar property of CultureInfo.DateTimeFormat to a new Calendar.
