About these holidays in Iran (2027)
Our Iran public holidays guide explains the background of each holiday and how the dates are set.
Isra' and Mi'raj (estimated)
Isra and Mi'raj commemorates the night journey of the Prophet Muhammad from Mecca to Jerusalem and his ascension through the heavens, observed on the twenty seventh day of Rajab. It is a public holiday in several Muslim majority countries, marked with evening prayers, recitations and storytelling. The Gregorian date moves about eleven days earlier each year, so calendars list it as estimated until the moon sighting confirms it.
Eid al-Fitr (estimated)
Eid al-Fitr is the festival that ends Ramadan, the Islamic month of fasting, and begins on the first day of Shawwal. It is a two or three day public holiday across much of the Muslim world. The date depends on the sighting of the new moon, so published calendars mark it as estimated until it is confirmed. Families gather for prayer, shared meals and charitable giving before the fast was broken each evening of Ramadan.
Eid al-Fitr Holiday (estimated)
This is the second or third day of the Eid al-Fitr public holiday, which closes the month of Ramadan. Many Muslim majority countries extend the celebration over two or three days so that families can travel and gather. As with the first day, the date depends on the sighting of the Shawwal moon and therefore remains estimated until confirmed. Celebrations centre on shared meals, visiting relatives and giving to charity.
Eid al-Adha (estimated)
Eid al-Adha, the Feast of Sacrifice, falls on the tenth day of Dhu al-Hijjah during the annual Hajj pilgrimage. It honours the willingness of Ibrahim to sacrifice his son in obedience to God. Muslims who can afford it sacrifice an animal and share the meat with family, neighbours and the poor. Because the Islamic calendar is lunar, the Gregorian date moves about ten days earlier each year and is listed as estimated.
Ashura (estimated)
Ashura falls on the tenth day of Muharram, the first month of the Islamic calendar, and is observed for different reasons across the Muslim world. For Shia Muslims it is the central commemoration of the martyrdom of Husayn ibn Ali at Karbala, marked by mourning ceremonies. For many Sunni Muslims it is a day of voluntary fasting. It is a public holiday in several countries, and the date is published as estimated.
