Sepandārmazgān or Espandegān (اسپندگان), is an ancient Iranian day of women with Zoroastrian roots dating back to the first Persian Empire, the Achaemenid Empire. This day is dedicated to Spənta Ārmaiti, 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.
