Adar Parab

Adar Parab

March, April, November; ninth day of Adar, the ninth Zoroastrian month
Adar Parab is one of the "sacred name days" in the Zororastrian calendar, where the name of the day and the name of the month coincide. Adar, the spiritual being or yazata for whom both the day and the month are named, presides over fire and is associated with light and warmth. Parsis—as the Zoroastrians living in India are called—traditionally give their household fires a rest on this day by not cooking and by offering special prayers. It is also customary to recite the portion of the Avesta (Zoroastrian sacred writings) known as the Atash Niyayesh, "Fire Litany."
Fire is the most important symbol for the followers of Zoroaster (also known as Zarathushtra), a Persian religious leader believed to have lived around 1200 b.c.e. They have fire temples where fires burn constantly, as well as fires that are kindled in prayer halls and private homes for special services performed outside the temple.
The Zoroastrian calendar has 12 months of 30 days each, plus five extra days at the end of the year. Because of discrepancies in the calendars used by widely separated Zoroastrian communities around the world, there are now three different calendars in use, and the 9th of Adar can fall either in March, April, or November.
