The Gregorian calendar recognizes two eras: B.C. ( before Christ ) or B.C.E. ( before common era ), and A.D. ( Latin "Anno Domini", which means "in the year of the Lord" ) or C.E. ( common era ). This implementation of the GregorianCalendar class recognizes only the current era ( A.D. or C.E. ).
A leap year in the Gregorian calendar is defined as a year that is evenly divisible by four, except if it is divisible by 100; however, years that are divisible by 400 are leap years. For example, the year 1900 was not a leap year, but the year 2000 was. A common year has 365 days and a leap year has 366 days.
The Gregorian 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.
If the GregorianCalendar is selected in DateTimeFormatInfo.Calendar, DateTimeFormatInfo ignores punctuation in abbreviated era names; that is, "A.D." is equivalent to "AD".
