Sepandārmazgān (Persian: سپندارمذگان) is a Zoroastrian festival
Sepandārmazgān (Persian: سپندارمذگان) is a Zoroastrian festival. This day is dedicated to Spənta Ārmaiti (Avestan for "Holy Devotion", Spandārmad in Middle Persian, Persian: سپندارمذ Spendārmad or Sepandarmaz), the Amesha Spenta who is given the domain of "earth". The date of the festival as observed in the Sassanid era was on the 5th day of the month Spandarmad. When the name of the day and the month of the day were the same, a "name-feast" celebration was always done. According to the testimony of al-Biruni, in the 11th century CE there was a festival when the names of the day and the month were the same. The deity Spandarmad protected the Earth and the "good, chaste and beneficent wife who loves her husband". According to him, the festival used to be dedicated to women, and men would make them "liberal presents", and the custom was still flourishing in some districts of Fahla.
The jashn-e barzegarán (Festival of Agriculturists), is celebrated in Iran also on the 5th day of Spandarmad month (the Spandarmad day). People pray for good harvest, honor the deity of Earth Spandārmad, and put signs on doors to destroy evil spirits.
The observation of this festival has been revived in modern Iran, where it is mostly set on the 5th day of Esfand in the Solar Hejri calendar introduced in 1925, corresponding to 24 February. The modern festival is a celebration day of love towards mothers and wives.
