On the thirteenth day of the new year, which also marks the end of the Norooz holiday break for the students, families leave their houses and head for the outdoors where they eat, play games, and celebrate a happy and healthy holiday season.
This tradition is called Seezdah Bedar (seezdah means thirteen) which in English translates to "getting rid of thirteen". This fun and exciting outing involves all family members and is intended to end the holiday season on a relaxing and positive note. The concept of avoiding the number thirteen is mainly to symbolize the will and power to deal with all evil in the new year.
An interesting ritual performed at the end of the picnic day is to throw away the Sabzee from the Norooz Haft Seen table. The sabzee is supposed to have collected all the sickness, pain and ill fate hiding on the path of the family throughout the coming year! Touching someone else's sabzee on this thirteenth day or bringing it home is, therefore, not a good idea and may result in inviting their pain and hardship to oneself.
Another meaningful ritual performed with the dumping of the sabzee is that young single women tie the sabzee leaves prior to discarding it, symbolizing the wish to be tied in a marriage by the Seezdah Bedar of the following year!
