Sepandarmazgan (Esfand 5, Shahanshahi calendar), is an ancient Iranian festival observed on the fifth day of Esfand in the Shahanshahi calendar. The festival has roots in Zoroastrian tradition and is dedicated to the celebration of earth, fertility, and affection. The name Sepandarmazgan derives from the divinity Spandarmad, who in Zoroastrian belief is the guardian of the earth and symbolizes patience and humility. Historically, Sepandarmazgan was also regarded as a day to honor women and mothers. On this day, men would give gifts to the women in their families and express gratitude for their contributions to family life. This custom continues in some regions of Iran, and Sepandarmazgan remains a symbol of love and friendship in Iranian culture. The festival is marked by family gatherings, preparation of traditional foods, and appreciation of nature. Alongside other Iranian festivals, Sepandarmazgan forms part of the country’s cultural and historical identity, reflecting the longstanding connection between people, nature, and social values.
