Sadeh (Persian: سده also transliterated as Sade), is an Iranian festival that dates back to the Achaemenid Empire. Sadeh is celebrated 50 days before Nowruz. 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.
