This concrete subclass of Calendar implements the standard solar calendar with years numbered from the birth of Christ that is used is most locales throughout the world. You do not typically use this class directly, but instead obtain a Calendar object suitable for the default locale by calling Calendar.getInstance( ) . See Calendar for details on working with Calendar objects. There is a discontinuity in the Gregorian calendar that represents the historical switch from the Julian calendar to the Gregorian calendar. By default, GregorianCalendar assumes that this switch occurs on October 15, 1582. Most programs need not be concerned with the switch.
