✦ Why It Matters
Sadeh ("hundred") falls 50 days before Nowruz, meaning 100 days into winter (50 days + 50 nights). It celebrates the discovery and harnessing of fire by the mythical Persian king Hushang, and the power of light to overcome winter darkness.
✦ How It Is Observed
Large bonfires lit at dusk, gathering around the fire, music and celebration, prayers to Ahura Mazda. The bonfire symbolizes the power of light over darkness.
