Sizdah-bedar (Persian سیزده بدر) is the Persian Festival of springs. It is a full day of mass Outdoors Picnic, which occurs on the 13th day of Norouz (Persian Year), about April 4.
Iranians have a tradition of spending the day outdoors on the 13th day of month Farvardin. Sizdah- means thirteen, and -bedar, meaning to get rid of, i.e "getting rid of thirteen". From the ancient times, Iranian peoples have enjoyed this day, although it is also the day that marks the end of the Norouz celebrations.
The first 12 days of the year are very important, because they symbolise order in the world and in the lives of people. The 13th day marks the beginning of the return to ordinary daily life.
It is customary on this day, for families to pack a picnic and go to a park or the countryside. It is believed that joy and laughter clean the mind from all evil thoughts, and a picnic is usually a festive, happy event.
