GregorianCalendar |

Provides methods for manipulating dates using the Gregorian calendar mathematics.

The Gregorian calendar recognizes an era of BC (Before Christ) and AD (Anno Domino). The GregorianCalendar class only support the AD era (1).

The calendar supports the time from 01/01/0001 12:00:00AM to 12/31/9999 11:59:59PM.

Only leap year is recognized and occurs every 4 years, except a year that is evenly divisible by 100. However, if it is divisible by 400 then it is a leap year.

There are 12 months in the Gregorian calendar. The number of days range from 28 to 31, except on leap year when the shortest month is 29 days.
