HijrahChronology

INSTANCE

public static final HijrahChronology INSTANCE

Singleton instance of the Islamic Umm Al-Qura calendar of Saudi Arabia. Other Hijrah chronology variants may be available from Chronology.getAvailableChronologies.

date

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

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

date

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

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

date

public HijrahDate date (TemporalAccessor temporal)

dateEpochDay

public HijrahDate dateEpochDay (long epochDay)

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

dateNow

public HijrahDate dateNow (ZoneId zone)

dateNow

public HijrahDate dateNow ()

dateNow

public HijrahDate dateNow (Clock clock)

dateYearDay

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

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

dateYearDay

public HijrahDate dateYearDay (int prolepticYear, 
                int dayOfYear)

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

eraOf

public HijrahEra eraOf (int eraValue)

Creates the HijrahEra object from the numeric value. The Hijrah calendar system has only one era covering the proleptic years greater than zero. This method returns the singleton HijrahEra for the value 1.

eras

public List<Era> eras ()

getCalendarType

public String getCalendarType ()

Gets the calendar type of the Islamic calendar.

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).

getId

public String getId ()

Gets the ID of the chronology.

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

isLeapYear

public boolean isLeapYear (long prolepticYear)

localDateTime

public ChronoLocalDateTime<HijrahDate> localDateTime (TemporalAccessor temporal)

prolepticYear

public int prolepticYear (Era era, 
                int yearOfEra)

range

public ValueRange range (ChronoField field)

resolveDate

public HijrahDate resolveDate (Map<TemporalField, Long> fieldValues, 
                ResolverStyle resolverStyle)

Resolves parsed ChronoField values into a date during parsing.

Most TemporalField implementations are resolved using the resolve method on the field. By contrast, the ChronoField class defines fields that only have meaning relative to the chronology. As such, ChronoField date fields are resolved here in the context of a specific chronology.

ChronoField instances are resolved by this method, which may be overridden in subclasses.

• EPOCH_DAY - If present, this is converted to a date and all other date fields are then cross-checked against the date.
• PROLEPTIC_MONTH - If present, then it is split into the YEAR and MONTH_OF_YEAR. If the mode is strict or smart then the field is validated.
• YEAR_OF_ERA and ERA - If both are present, then they are combined to form a YEAR. In lenient mode, the YEAR_OF_ERA range is not validated, in smart and strict mode it is. The ERA is validated for range in all three modes. If only the YEAR_OF_ERA is present, and the mode is smart or lenient, then the last available era is assumed. In strict mode, no era is assumed and the YEAR_OF_ERA is left untouched. If only the ERA is present, then it is left untouched.
• YEAR, MONTH_OF_YEAR and DAY_OF_MONTH - If all three are present, then they are combined to form a date. In all three modes, the YEAR is validated. If the mode is smart or strict, then the month and day are validated. If the mode is lenient, then the date is combined in a manner equivalent to creating a date on the first day of the first month in the requested year, then adding the difference in months, then the difference in days. If the mode is smart, and the day-of-month is greater than the maximum for the year-month, then the day-of-month is adjusted to the last day-of-month. If the mode is strict, then the three fields must form a valid date.
• YEAR and DAY_OF_YEAR - If both are present, then they are combined to form a date. In all three modes, the YEAR is validated. If the mode is lenient, then the date is combined in a manner equivalent to creating a date on the first day of the requested year, then adding the difference in days. If the mode is smart or strict, then the two fields must form a valid date.
• YEAR, MONTH_OF_YEAR, ALIGNED_WEEK_OF_MONTH and ALIGNED_DAY_OF_WEEK_IN_MONTH - If all four are present, then they are combined to form a date. In all three modes, the YEAR is validated. If the mode is lenient, then the date is combined in a manner equivalent to creating a date on the first day of the first month in the requested year, then adding the difference in months, then the difference in weeks, then in days. If the mode is smart or strict, then the all four fields are validated to their outer ranges. The date is then combined in a manner equivalent to creating a date on the first day of the requested year and month, then adding the amount in weeks and days to reach their values. If the mode is strict, the date is additionally validated to check that the day and week adjustment did not change the month.
• YEAR, MONTH_OF_YEAR, ALIGNED_WEEK_OF_MONTH and DAY_OF_WEEK - If all four are present, then they are combined to form a date. The approach is the same as described above for years, months and weeks in ALIGNED_DAY_OF_WEEK_IN_MONTH. The day-of-week is adjusted as the next or same matching day-of-week once the years, months and weeks have been handled.
• YEAR, ALIGNED_WEEK_OF_YEAR and ALIGNED_DAY_OF_WEEK_IN_YEAR - If all three are present, then they are combined to form a date. In all three modes, the YEAR is validated. If the mode is lenient, then the date is combined in a manner equivalent to creating a date on the first day of the requested year, then adding the difference in weeks, then in days. If the mode is smart or strict, then the all three fields are validated to their outer ranges. The date is then combined in a manner equivalent to creating a date on the first day of the requested year, then adding the amount in weeks and days to reach their values. If the mode is strict, the date is additionally validated to check that the day and week adjustment did not change the year.
• YEAR, ALIGNED_WEEK_OF_YEAR and DAY_OF_WEEK - If all three are present, then they are combined to form a date. The approach is the same as described above for years and weeks in ALIGNED_DAY_OF_WEEK_IN_YEAR. The day-of-week is adjusted as the next or same matching day-of-week once the years and weeks have been handled.

The default implementation is suitable for most calendar systems. If ChronoField.YEAR_OF_ERA is found without an ChronoField.ERA then the last era in Chronology.eras() is used. The implementation assumes a 7 day week, that the first day-of-month has the value 1, that first day-of-year has the value 1, and that the first of the month and year always exists.
