BuddhistCalendar
is a subclass of GregorianCalendar
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.
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.
The Buddhist Calendar has only one allowable era: BE
. If the
calendar is not in lenient mode (see setLenient
), dates before
1/1/1 BE are rejected with an IllegalArgumentException
.
This class should not be subclassed.
BuddhistCalendar usually should be instantiated using
Calendar.getInstance(ULocale)
passing in a ULocale
with the tag "@calendar=buddhist"
.

Public methods
getType
public String getType ()
[icu] Returns the calendar type name string for this Calendar object. The returned string is the legacy ICU calendar attribute value, for example, "gregorian" or "japanese".
See type="old type name" for the calendar attribute of locale IDs at http://www.unicode.org/reports/tr35/#Key_Type_Definitions
Returns | |
---|---|
String |
legacy calendar type name string |
Protected methods
handleComputeFields
protected void handleComputeFields (int julianDay)
Override Calendar to compute several fields specific to the hybrid Gregorian-Julian calendar system. These are:
- ERA
- YEAR
- MONTH
- DAY_OF_MONTH
- DAY_OF_YEAR
- EXTENDED_YEAR
Parameters | |
---|---|
julianDay |
int |
handleComputeMonthStart
protected int handleComputeMonthStart (int eyear, int month, boolean useMonth)
Return JD of start of given month/year
Parameters | |
---|---|
eyear |
int : the extended year |
month |
int : the zero-based month, or 0 if useMonth is false |
useMonth |
boolean : if false, compute the day before the first day of
the given year, otherwise, compute the day before the first day of
the given month |
Returns | |
---|---|
int |
the Julian day number of the day before the first day of the given month and year |
handleGetExtendedYear
protected int handleGetExtendedYear ()
Returns the extended year defined by the current fields. This will use the EXTENDED_YEAR field or the YEAR and supra-year fields (such as ERA) specific to the calendar system, depending on which set of fields is newer.
Returns | |
---|---|
int |
the extended year |
handleGetLimit
protected int handleGetLimit (int field, int limitType)
Override GregorianCalendar. There is only one Buddhist ERA. We should really handle YEAR, YEAR_WOY, and EXTENDED_YEAR here too to implement the 1..5000000 range, but it's not critical.
Parameters | |
---|---|
field |
int : one of the above field numbers |
limitType |
int : one of MINIMUM , GREATEST_MINIMUM ,
LEAST_MAXIMUM , or MAXIMUM |
Returns | |
---|---|
int |
