Ritu (Indian season)

For other uses see Ritu (disambiguation).

Ritu (Sanskrit: ऋतु) means "season" in various South Asian calendars, and there are six ritus (also transliterated rutu) or seasons. The word is derived from the Vedic Sanskrit word Rtu, a fixed or appointed time, especially the proper time for sacrifice (yajna) or ritual in Vedic Religion; this in turn comes from the word Rta (ऋत), as used in Vedic Sanskrit literally means the "order or course of things". This word is used in nearly all Indian languages.
