Nowruz, the Persian New Year, is celebrated on the first day of spring and marks the beginning of the year in the Iranian calendar. Families prepare for this festive occasion by cleaning their homes, symbolizing a fresh start. They also set up a special table called Haft-Seen, which includes seven items starting with the Persian letter "S," each representing different hopes for the new year, such as health, wealth, and love. During Nowruz, people visit friends and family, exchanging gifts and sharing meals. Traditional foods like sabzi polo (herbed rice) and fish are commonly served. Celebrations often include music, dancing, and various cultural performances, bringing communities together in joy and unity.
