Zoroastrian celebrations are rooted in the ancient religion founded by Zoroaster, emphasizing the duality of good and evil. One of the most significant festivals is Nowruz, the Persian New Year, celebrated on the spring equinox. It symbolizes renewal and the triumph of light over darkness, featuring rituals like cleaning homes and sharing meals with family. Another important celebration is Gahambars, which are seasonal festivals that honor creation and the elements. Each Gahambar lasts for five days and includes communal prayers, feasting, and charitable acts, fostering community spirit and gratitude for nature's gifts.
