public class BuddhistCalendar
extends GregorianCalendar

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".

Method Details

handleGetExtendedYear

protected int handleGetExtendedYear()

Description copied from class: Calendar

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.

Overrides:

handleGetExtendedYear in class GregorianCalendar

Returns:

the extended year

handleComputeMonthStart

protected int handleComputeMonthStart(int eyear,
 int month,
 boolean useMonth)

Description copied from class: GregorianCalendar

Return JD of start of given month/year

Overrides:

handleComputeMonthStart in class GregorianCalendar

Parameters:

eyear - the extended year

month - the zero-based month, or 0 if useMonth is false

useMonth - 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:

the Julian day number of the day before the first day of the given month and year

handleComputeFields

protected void handleComputeFields(int julianDay)

Description copied from class: GregorianCalendar

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

Overrides:

handleComputeFields in class GregorianCalendar

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.

Overrides:

handleGetLimit in class GregorianCalendar

Parameters:

field - one of the above field numbers

limitType - one of MINIMUM, GREATEST_MINIMUM, LEAST_MAXIMUM, or MAXIMUM

getType

public String getType()

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

Overrides:

getType in class GregorianCalendar

Returns:

legacy calendar type name string

isEra0CountingBackward

@Deprecated
protected boolean isEra0CountingBackward()

Deprecated.

This API is ICU internal only.

The year in this calendar is counting from 1 backward if the era is 0.

Overrides:

isEra0CountingBackward in class GregorianCalendar

Returns:

The year in era 0 of this calendar is counting backward from 1.
