*** ** * ** ***

The Hijrah calendar is a lunar calendar supporting Islamic calendars.


The HijrahChronology follows the rules of the Hijrah calendar system. The Hijrah
calendar has several variants based on differences in when the new moon is
determined to have occurred and where the observation is made.
In some variants the length of each month is
computed algorithmically from the astronomical data for the moon and earth and
in others the length of the month is determined by an authorized sighting
of the new moon. For the algorithmically based calendars the calendar
can project into the future.
For sighting based calendars only historical data from past
sightings is available.


The length of each month is 29 or 30 days.
Ordinary years have 354 days; leap years have 355 days.


CLDR and LDML identify variants:

| Chronology ID | Calendar Type | Locale extension, see `https://developer.android.com/reference/java/util/Locale` | Description |
| Hijrah-umalqura | islamic-umalqura | ca-islamic-umalqura | Islamic - Umm Al-Qura calendar of Saudi Arabia |
|---|---|---|---|
[Variants of Hijrah Calendars]

Additional variants may be available through `https://developer.android.com/reference/java/time/chrono/Chronology#getAvailableChronologies()`.

Example


Selecting the chronology from the locale uses `https://developer.android.com/reference/java/time/chrono/Chronology#ofLocale(java.util.Locale)`
to find the Chronology based on Locale supported BCP 47 extension mechanism
to request a specific calendar ("ca"). For example,

```
     Locale locale = Locale.forLanguageTag("en-US-u-ca-islamic-umalqura");
     Chronology chrono = Chronology.ofLocale(locale);
```

### resolveDate

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
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 `https://developer.android.com/reference/java/time/temporal/ChronoField#YEAR_OF_ERA` is found without an `https://developer.android.com/reference/java/time/temporal/ChronoField#ERA`
then the last era in `https://developer.android.com/reference/java/time/chrono/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.
