Sizdah Bedar is an Iranian festival celebrated on the 13th day of Nowruz, the Persian New Year. It marks the end of the Nowruz celebrations and is a day dedicated to nature and outdoor activities. Families typically spend the day picnicking in parks or countryside, enjoying food, games, and the company of loved ones. A key tradition of Sizdah Bedar is the symbolic act of throwing away sabzeh, which are sprouted greens prepared for the New Year. This act represents the removal of bad luck and the welcoming of a fresh start. The day emphasizes the importance of nature and community in Iranian culture.
