About the Zoroastrian calendar

Zoroastrian calendars have twelve months of 30 days, each day dedicated to a divinity, plus five Gatha days. Disputes over intercalation produced three variants still in use among Parsis and Iranian Zoroastrians: Shahanshahi, Kadmi and Fasli, the last fixed to the March equinox. Years are traditionally counted from the accession of Yazdegerd III, the last Sasanian king, in 632.
