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.
