Mehregan
مهرگان
Mehregan (مهرگان) is a Zoroastrian and Iranian autumn festival. It is celebrated on the 16th day of Mehr in the Iranian calendar and honours Mithra.

What happens
At Mehregan, a visitor would see people dressed in new clothes, with purple associated with the day. The gathering centres on a Mehregan table, laid with foods and symbolic items for the occasion.
Family and friends exchange gifts as part of the celebration. The day is also linked with the legend of Fereydun, who is said to have defeated the tyrant Zahhak on this day, and the festival is understood as marking that victory.
Why it matters
Mehregan matters as an autumn feast of friendship, affection and love. It honours Mithra, and its customs express that meaning through new clothes, a laid table, and gifts exchanged among family and friends. The festival is also read as the day Fereydun overcame the tyrant Zahhak, giving it the character of a victory as well as a harvest celebration. It is one of the oldest continuously observed Iranian festivals and is paired with Nowruz as one of the two great feasts of the Iranian year. The Ceremony of Mehregan was inscribed in 2024 on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity.
