HebrewCalendar is a subclass of Calendar that that implements the traditional Hebrew calendar. This is the civil calendar in Israel and the liturgical calendar of the Jewish faith worldwide.

The Hebrew calendar is lunisolar and thus has a number of interesting properties that distinguish it from the Gregorian. Months start on the day of (an arithmetic approximation of) each new moon. Since the solar year (approximately 365.24 days) is not an even multiple of the lunar month (approximately 29.53 days) an extra "leap month" is inserted in 7 out of every 19 years. To make matters even more interesting, the start of a year can be delayed by up to three days in order to prevent certain holidays from falling on the Sabbath and to prevent certain illegal year lengths. Finally, the lengths of certain months can vary depending on the number of days in the year.

The leap month is known as "Adar 1" and is inserted between the months of Shevat and Adar in leap years. Since the leap month does not come at the end of the year, calculations involving month numbers are particularly complex. Users of this class should make sure to use the roll and add methods rather than attempting to perform date arithmetic by manipulating the fields directly.

Note: In the traditional Hebrew calendar, days start at sunset. However, in order to keep the time fields in this class synchronized with those of the other calendars and with local clock time, we treat days and months as beginning at midnight, roughly 6 hours after the corresponding sunset.

If you are interested in more information on the rules behind the Hebrew calendar, see one of the following references:

• "Calendrical Calculations", by Nachum Dershowitz & Edward Reingold, Cambridge University Press, 1997, pages 85-91.

• The Calendar FAQ, http://www.faqs.org/faqs/calendars/faq/

This class should not be subclassed.

HebrewCalendar usually should be instantiated using Calendar.getInstance(ULocale) passing in a ULocale with the tag "@calendar=hebrew".

Public methods

add

Added in API level 24

public void add (int field, 
                int amount)

Add a signed amount to a specified field, using this calendar's rules. For example, to add three days to the current date, you can call add(Calendar.DATE, 3).

When adding to certain fields, the values of other fields may conflict and need to be changed. For example, when adding one to the MONTH field for the date "30 Av 5758", the DAY_OF_MONTH field must be adjusted so that the result is "29 Elul 5758" rather than the invalid "30 Elul 5758".

This method is able to add to all fields except for ERA, DST_OFFSET, and ZONE_OFFSET.

Note: You should always use roll and add rather than attempting to perform arithmetic operations directly on the fields of a HebrewCalendar. Since the MONTH field behaves discontinuously in non-leap years, simple arithmetic can give invalid results.

Parameters
field	int: the time field.
amount	int: the amount to add to the field.

Throws
IllegalArgumentException	if the field is invalid or refers to a field that cannot be handled by this method.

getType

Added in API level 24

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

roll

Added in API level 24

public void roll (int field, 
                int amount)

Rolls (up/down) a specified amount time on the given field. For example, to roll the current date up by three days, you can call roll(Calendar.DATE, 3). If the field is rolled past its maximum allowable value, it will "wrap" back to its minimum and continue rolling. For example, calling roll(Calendar.DATE, 10) on a Hebrew calendar set to "25 Av 5758" will result in the date "5 Av 5758".

When rolling certain fields, the values of other fields may conflict and need to be changed. For example, when rolling the MONTH field upward by one for the date "30 Av 5758", the DAY_OF_MONTH field must be adjusted so that the result is "29 Elul 5758" rather than the invalid "30 Elul".

This method is able to roll all fields except for ERA, DST_OFFSET, and ZONE_OFFSET. Subclasses may, of course, add support for additional fields in their overrides of roll.

Note: You should always use roll and add rather than attempting to perform arithmetic operations directly on the fields of a HebrewCalendar. Since the MONTH field behaves discontinuously in non-leap years, simple arithmetic can give invalid results.

Parameters
field	int: the time field.
amount	int: the amount by which the field should be rolled.

Throws
IllegalArgumentException	if the field is invalid or refers to a field that cannot be handled by this method.

Protected methods

handleComputeFields

Added in API level 24

protected void handleComputeFields (int julianDay)

Subclasses may override this method to compute several fields specific to each calendar system. These are:

• ERA
• YEAR
• MONTH
• DAY_OF_MONTH
• DAY_OF_YEAR
• EXTENDED_YEAR

Subclasses can refer to the DAY_OF_WEEK and DOW_LOCAL fields, which will be set when this method is called. Subclasses can also call the getGregorianXxx() methods to obtain Gregorian calendar equivalents for the given Julian day.

In addition, subclasses should compute any subclass-specific fields, that is, fields from BASE_FIELD_COUNT to getFieldCount() - 1.

Parameters
julianDay	int

handleComputeMonthStart

Added in API level 24

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

Added in API level 24

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

Added in API level 24

protected int handleGetLimit (int field, 
                int limitType)

Subclass API for defining limits of different types. Subclasses must implement this method to return limits for the following fields:

ERA
 YEAR
 MONTH
 WEEK_OF_YEAR
 WEEK_OF_MONTH
 DAY_OF_MONTH
 DAY_OF_YEAR
 DAY_OF_WEEK_IN_MONTH
 YEAR_WOY
 EXTENDED_YEAR

Parameters
field	int: one of the above field numbers
limitType	int: one of MINIMUM, GREATEST_MINIMUM, LEAST_MAXIMUM, or MAXIMUM

Returns
int

handleGetMonthLength

Added in API level 24

protected int handleGetMonthLength (int extendedYear, 
                int month)

Returns the length of the given month in the given year

Parameters
extendedYear	int
month	int

Returns
int

handleGetYearLength

Added in API level 24

protected int handleGetYearLength (int eyear)

Returns the number of days in the given Hebrew year

Parameters
eyear	int

Returns
int
