Eid al-Fitr is an extremely significant holiday in Iran, known locally as Eid-e-Fetr. This auspicious holiday marks the end of the holy month of Ramadan, during which Muslims around the world fast from dawn to dusk. Eid al-Fitr is observed on the first day of the Islamic month of Shawwal, right after the conclusion of the Ramadan fast. The actual day of celebration varies each year, due to the Islamic lunar calendar.

Eid al-Fitr, an official national holiday in Iran, encourages acts of charity and community bonding. From prayers at the mosque to widespread feasts at home involving friends and family, the spirit of togetherness shines brightly during this time. A hallmark of this holiday is the act of giving Zakat-al-Fitr, a form of charity that involves providing those less fortunate with resources to celebrate the holiday. Traditional foods are also a key part of the celebration, with special cookies known as Shirini Eid and meals comprising of rice, called Polo, and stew, known as Khoresht, being popular.

Another focal point of Eid al-Fitr in Iran is the renewal of spiritual commitment. It is seen as an opportunity to renew faith, seek forgiveness, and purify one's heart. Communities come together for special prayers, known as Salat al-Eid conducted at mosques and prayer grounds. Iranian people also visit the graves of their loved ones during this period, remembering them and praying for their peaceful rest. Irrespective of age or social status, the emphasis on unity, forgiveness, and charity makes this Eid al-Fitr an integral part of Iranian culture.
