Gahambars
The seasonal festivals, called gahambars, occur six times a year. Due to the peculiarities of the Shahenshahi and Kadmi variants of the Zoroastrian calendar, in those variants the seasonal festivals are actually celebrated many months in advance and are therefore said to reflect the six "primordial creations" of Ahura Mazda, otherwise known as the Amesha Spentas. Each of these festivals is celebrated over five days. The six festivals are:
- Maidyozarem Gahambar, April 30 – May 4
- Maidyoshahem Gahambar, June 29 – July 3
- Paitishahem Gahambar, September 12 – September 16
- Ayathrem Gahambar, October 12 – October 16
- Maidyarem Gahambar, December 31 – January 4
- Hamaspathmaidyem Gahambar, March 16 – March 20
