Hindu holidays recurrence rules are either based on the Hindu Lunar Calendar or the Hindu Solar Calendar. Most Hindu holidays are based on the Lunar Calendar.

 

Lunar holidays are based on a lunar month-day pair. Very few of the lunar holidays use the leap month if exists option (note that in the Hindu lunar calendar, the leap month occurs before the normal month). When a lunar month is repeated, holidays are held in the second of the 2 month, the non-leap month (this is similar to the rule for Jewish holidays). However, lunar holidays almost always occur on the leap day option.

The calculation of Hindu Lunar holidays is extremely complex and requires repeated trial and errors tests by the program. Therefore it is normal for the sample dates to take a noticeable amount of time (about 1 second) to display each time you modify, or display, a Hindu Lunar holiday recurrence rule.

 

Note that when the date of a holiday based on the Hindu Lunar calendar is expunged (ie. does not occur) Q++ now uses the following date that exists in the Hindu Lunar calendar. For example, Nyepi (Hindu Lunar New Year) should occur on the first day of the month of Chaitra, but in 2007 Chaitra 1 is expunged (ie. the Hindu Lunar calendar goes from the last day of the previous year, Phalguna 30 on March 19, to Chaitra 2 on March 20). In that case we would display the date of Chitra 2, March 20 2007, for Nyepi. This is justified by the fact that the Hindu Lunar day begins at sunrise, and that for a lunar day to be expunged it must occur less than an hour before sunrise, hence the expunged day's start is already in the next day of the Western calendar whose days begin at midnight. However, as always, local practice concerning expunged days may vary regionally.

 

Solar holidays are simply based on a solar month-day pair.

The Hindu Solar year begins around April 14th every year.
