Nature Day, also known as Sizdah-Bedar, is a beloved traditional holiday celebrated in Iran. This annual event takes place on the 13th day of Farvardin, the first month in the Iranian calendar, which falls within the first or second week of April in the Gregorian calendar. This festival marks the end of the Nowruz celebrations, a period of new beginnings symbolised by the Persian New Year.
The overall concept of Nature Day is to appreciate and respect the environment. Iranians traditionally spend this day outdoors in local parks or rural areas to have picnics with family and friends, thereby respecting the beauty of nature. One of the most common customs is to dispose of the 'Sabzeh' from the Nowruz Haft-Seen table. The Sabzeh, or wheatgrass, is usually thrown into running water, a symbol to wish away any bad luck or misfortune and to beckon prosperity and health for the coming year.
Nature Day is an important part of Iranian culture and tradition. Despite any political, religious, or social differences, it is a day when everyone comes together to celebrate the beauty of nature in unity. People from all walks of life participate in this unique festival, making it one of the most widely observed holidays in Iran. In recent years, this event has also taken on a significant environmental meaning, as it promotes environmental awareness and encourages stewardship of the planet.
