Sadeh is an ancient Persian festival celebrated in Iran, marking the mid-winter season. It typically occurs on the 10th day of the month of Bahman in the Iranian calendar, which usually falls in late January or early February. The festival symbolizes the victory of light over darkness and the arrival of spring, as it is a time to celebrate the warmth of fire and the sun. During Sadeh, people gather around bonfires, sing songs, and share traditional foods. The festival also involves rituals that honor the Zoroastrian elements, particularly fire, which is considered sacred. Sadeh serves as a reminder of the importance of community and the changing seasons.
