public final class ThaiBuddhistChronology
extends AbstractChronology
implements Serializable

The Thai Buddhist calendar system.

This chronology defines the rules of the Thai Buddhist calendar system. This calendar system is primarily used in Thailand. Dates are aligned such that 2484-01-01 (Buddhist) is 1941-01-01 (ISO).

The fields are defined as follows:

era - There are two eras, the current 'Buddhist' (ERA_BE) and the previous era (ERA_BEFORE_BE).
year-of-era - The year-of-era for the current era increases uniformly from the epoch at year one. For the previous era the year increases from one as time goes backwards. The value for the current era is equal to the ISO proleptic-year plus 543.
proleptic-year - The proleptic year is the same as the year-of-era for the current era. For the previous era, years have zero, then negative values. The value is equal to the ISO proleptic-year plus 543.
month-of-year - The ThaiBuddhist month-of-year exactly matches ISO.
day-of-month - The ThaiBuddhist day-of-month exactly matches ISO.
day-of-year - The ThaiBuddhist day-of-year exactly matches ISO.
leap-year - The ThaiBuddhist leap-year pattern exactly matches ISO, such that the two calendars are never out of step.

Fields

INSTANCE

public static final ThaiBuddhistChronology INSTANCE

Singleton instance of the Buddhist chronology.

Methods

getId

public String getId()

Gets the ID of the chronology - 'ThaiBuddhist'.

The ID uniquely identifies the Chronology. It can be used to lookup the Chronology using Chronology.of(String).

Specified by:: getId in interface Chronology
Returns:: the chronology ID - 'ThaiBuddhist'
See Also:: getCalendarType()

getCalendarType

public String getCalendarType()

Gets the calendar type of the underlying calendar system - 'buddhist'.

The calendar type is an identifier defined by the Unicode Locale Data Markup Language (LDML) specification. It can be used to lookup the Chronology using Chronology.of(String). It can also be used as part of a locale, accessible via Locale.getUnicodeLocaleType(String) with the key 'ca'.

Specified by:: getCalendarType in interface Chronology
Returns:: the calendar system type - 'buddhist'
See Also:: getId()

date

public ThaiBuddhistDate date(Era era,
                             int yearOfEra,
                             int month,
                             int dayOfMonth)

Obtains a local date in Thai Buddhist calendar system from the era, year-of-era, month-of-year and day-of-month fields.

Specified by:: date in interface Chronology
Parameters:: era - the Thai Buddhist era, not null; yearOfEra - the year-of-era; month - the month-of-year; dayOfMonth - the day-of-month
Returns:: the Thai Buddhist local date, not null
Throws:: DateTimeException - if unable to create the date; ClassCastException - if the era is not a ThaiBuddhistEra

date

public ThaiBuddhistDate date(int prolepticYear,
                             int month,
                             int dayOfMonth)

Obtains a local date in Thai Buddhist calendar system from the proleptic-year, month-of-year and day-of-month fields.

Specified by:: date in interface Chronology
Parameters:: prolepticYear - the proleptic-year; month - the month-of-year; dayOfMonth - the day-of-month
Returns:: the Thai Buddhist local date, not null
Throws:: DateTimeException - if unable to create the date

dateYearDay

public ThaiBuddhistDate dateYearDay(Era era,
                                    int yearOfEra,
                                    int dayOfYear)

Obtains a local date in Thai Buddhist calendar system from the era, year-of-era and day-of-year fields.

Specified by:: dateYearDay in interface Chronology
Parameters:: era - the Thai Buddhist era, not null; yearOfEra - the year-of-era; dayOfYear - the day-of-year
Returns:: the Thai Buddhist local date, not null
Throws:: DateTimeException - if unable to create the date; ClassCastException - if the era is not a ThaiBuddhistEra

dateYearDay

public ThaiBuddhistDate dateYearDay(int prolepticYear,
                                    int dayOfYear)

Obtains a local date in Thai Buddhist calendar system from the proleptic-year and day-of-year fields.

Specified by:: dateYearDay in interface Chronology
Parameters:: prolepticYear - the proleptic-year; dayOfYear - the day-of-year

dateEpochDay

public ThaiBuddhistDate dateEpochDay(long epochDay)

Obtains a local date in the Thai Buddhist calendar system from the epoch-day.

Specified by:: dateEpochDay in interface Chronology
Parameters:: epochDay - the epoch day

Throws:: DateTimeException - if unable to create the date

isLeapYear

public boolean isLeapYear(long prolepticYear)

Checks if the specified year is a leap year.

Specified by:: isLeapYear in interface Chronology
Parameters:: prolepticYear - the proleptic-year to check, not validated for range
Returns:: true if the year is a leap year
