* <P>
|
|
* <code>BuddhistCalendar</code> is a subclass of <code>GregorianCalendar</code>
|
|
* that numbers years since the birth of the Buddha. This is the civil calendar
|
|
* in some predominantly Buddhist countries such as Thailand, and it is used for
|
|
* religious purposes elsewhere.
|
|
* <p>
|
|
* The Buddhist calendar is identical to the Gregorian calendar in all respects
|
|
* except for the year and era. Years are numbered since the birth of the
|
|
* Buddha in 543 BC (Gregorian), so that 1 AD (Gregorian) is equivalent to 544
|
|
* BE (Buddhist Era) and 1998 AD is 2541 BE.
|
|
* <p>
|
|
* The Buddhist Calendar has only one allowable era: <code>BE</code>. If the
|
|
* calendar is not in lenient mode (see <code>setLenient</code>), dates before
|
|
* 1/1/1 BE are rejected as an illegal argument.
