Sadeh in Persian means "hundred" and refers to the one hundred days and nights remaining to the beginning of spring. Sadeh is a mid-winter festival that was celebrated with grandeur and magnificence in ancient Persia. It was a festivity to honor fire and to defeat the forces of darkness, frost, and cold.

This corresponds to the night of December 20/21 (±1) in the Gregorian calendar, and to the night between the last day of the ninth month (Azar) and the first day of the tenth month (Dey) of the Iranian solar calendar.The longest and darkest night of the year is a time when friends and family gather together to eat, drink and read poetry (especially Hafez) and Shahnameh until well after midnight. Fruits and nuts are eaten and pomegranates and watermelons are particularly significant. The red colour in these fruits symbolizes the crimson hues of dawn and the glow of life. The poems of Divan-e Hafez, which can be found in the bookcases of most Iranian families, are read or recited on various occasions such as this festival and Nowruz. Shab-e Yalda was officially added to UNESCO Intangible Cultural Heritage Lists in December 2022.

Chaharshanbeh Suri or Charshanbeh Suri (Persian: چهارشنبه‌سوری, Čahāršanbe suri; lit. 'Scarlet Wednesday'), is an Iranian festival of the fire dance celebrated on the eve of the last Wednesday of the year, of ancient Zoroastrian origin. It is the first festivity of Nowruz, the Iranian New Year.

Sepandārmazgān (Persian: سپندارمذگان) or Espandegān (اسپندگان), is an ancient Iranian day of women with Zoroastrian roots. 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 Pahla.
