If Navroz is the Persian equivalent of Easter, Chaharshanbeh Souri, in many ways is the equivalent of Halloween. The event is celebrated on the eve of Navroz.

Chahar-Shanbeh means Wednesday and Souri means both 'Red' and 'Celebration'. In this “red celebration” which takes place on the last Wednesday of the solar calendar, people go out and make bush fires and keep them burning till the next morning. This is symbolic of burning all that was bad…pain, unhappiness, sickness and worry and looking forward to a new beginning.(hotel iran)
