Irans Zoroastrian community held the Jashn-e-Sadeh Festival for celebrating the discovery of fire on the 10th of the Iranian month of Bahman (Jan. 29).
Considered one of the biggest Persian festivities in ancient times, Jashn-e-Sadeh (also known as the day of kindness) is celebrated by Zoroastrians throughout the world.
Sadeh is a mid-winter festival celebrated 50 days before Norouz (the Persian New Year starting on March 21) to honor fire and to defeat darkness and cold. The name Sadeh, meaning hundred in Persian, refers to the total of 100 days and nights left to the beginning of the New Year.
The festival dates back to the time of Houshang, the first Kianid king who discovered how to light a fire.
