Chaharshanbe Suri
Chaharshanbeh Suri or Charshanbeh Suri or Chahar-shanbe suri (Persian: چهارشنبهسوری, romanized: Čahāršanbe suri, pronounced čāršambe suri; lit. 'The Scarlet Wednesday' or 'Feast of the last Wednesday of the year'), is an Iranian festival of the fire dance celebrated on the eve of the last Wednesday of the year, of ancient Zoroastrian origin. Since the event takes place in the final week of the year, it can also be regarded as a prelude to the New Year celebration of Nowruz.
