Time cycles in India
The time cycles in India are:
* 60-year cycle
* Year
* 6 seasons of a year
* about 60 days (2 months) in a season
* Month (lunar)
* 2 pakshas in a month, shukla (waxing) and krishna (waning)
* 15 tithis in a paksha (1-14, 15th is purnima or amavasya)
* 60 ghatikas (or 30 muhurtas or 8 praharas) in a 24-hour period (ahoratra).

Date conversion
Converting a date from an Indian calendar to the common era can require a complex computation. To obtain the approximate year in the common era (CE):
* Chaitradi Vikram (past) : Chaitra-Pausha: subtract 57; Pausha-Phalguna: subtract 56.
* Shaka: add 78-79
* Kalachuri: add 248-249
* Gupta/Valabhi: add 319-320
* Bangla: add 593-594
*Vira Nirvana : subtract 527-526Variations
* In UP/Rajasthan, months are purnimanta. In Gujarat/Maharashtra, they are amanta.
* In inscriptions, the years may be gata (past) or current.ee also
