NAME

Calendar::Saka - Interface to Indian Calendar.

VERSION

Version 1.34

DESCRIPTION

Module to play with Saka calendar mostly used in the South indian, Goa and Maharashatra. It supports the functionality to add / minus days, months and years to a Saka date. It can also converts Saka date to Gregorian/Julian date.

The Saka eras are lunisolar calendars, and feature annual cycles of twelve lunar months, each month divided into two phases: the 'bright half' (shukla) and the 'dark half' (krishna); these correspond respectively to the periods of the 'waxing' and the 'waning' of the moon. Thus, the period beginning from the first day after the new moon and ending on the full moon day constitutes the shukla paksha or 'bright half' of the month the period beginning from the day after the full moon until & including the next new moon day constitutes the krishna paksha or 'dark half' of the month.

The "year zero" corresponds to 78 BCE in the Saka calendar. The Saka calendar begins with the month of Chaitra (March) and the Ugadi/Gudi Padwa festivals mark the new year.

Each month in the Shalivahana calendar begins with the 'bright half' and is followed by the 'dark half'. Thus, each month of the Shalivahana calendar ends with the no-moon day and the new month begins on the day after that.

A variant of the Saka Calendar was reformed & standardized as the Indian National calendar in 1957. This official calendar follows the Shalivahan Shak calendar in beginning from the month of Chaitra and counting years with 78 CE being year zero. It features a constant number of days in every month with leap years.Saka Calendar for the month of Chaitra year 1937
