Important Dates of the Ahl al-Bayt: A Sunni Calendar

The dates below gather the days most associated with the Ahl al-Bayt, framed within what the Sunni tradition recognises and accepts. Many rest on authentic, agreed reports; others are traditional dates for which the sources differ, and these are marked “trad.” or noted as such. The list distinguishes between days of actual Sunni observance and events that Sunnis honour and remember historically without keeping as festivals.

The Calendar of the Prophetic Household

How These Days Sit Within Sunni Practice

Sunni practice keeps a small number of these as days of worship or celebration: the two Eids (1 Shawwal and 10 Dhu al-Hijjah), the Day of Arafah (9 Dhu al-Hijjah), the fast of Ashura (10 Muharram), and — among many though not all — the Mawlid (12 Rabi al-Awwal) and the night of mid-Shaban (15 Shaban).

The remaining dates are remembered with love and honour rather than observed as festivals. The births and passings of Ali, Fatima, Hasan and Husayn رضي الله عنهما, the events of Ghadir Khumm and Mubahala, and the days of the Karbala narrative are all recognised in Sunni historical and exegetical literature — and honouring the memory of the Prophet’s ﷺ family is, as the scholars affirmed, part of Sunni devotion. What the Sunni tradition avoids is turning these remembrances into fixed acts of worship for which there is no established basis, or into occasions of sectarian dispute.

A number of the household dates above — particularly the births and passings of the later Imams and of Sayyida Zaynab رضي الله عنها — are traditional rather than firmly established, and the sources differ over them. They are included for remembrance, clearly marked, because of their place in the story of the Prophet’s ﷺ family and their connection to articles across this site. A few further dates are sometimes mentioned but rest on uncertain or contested reports — for example, the marriage of Ali رضي الله عنه and Sayyidah Fatima al-Zahra عليها السلام (commonly placed in the second year after the Hijra, with the month variously given) and the precise birth date of Fatima al-Zahra عليها السلام (Sunni reports vary, often placing it some years before the Prophethood). These are left out of the table, or flagged, precisely because the dating cannot be firmly established.

Note: Islamic dates shift relative to the Gregorian calendar each year, and several of the dates above are traditional rather than precisely established. They are offered for remembrance, not as a fixed liturgical calendar.

Which dates of the Ahl al-Bayt does Sunni Islam actually observe?

Sunni practice keeps only a small number as days of worship or celebration: the two Eids (1 Shawwal and 10 Dhu al-Hijjah), the Day of Arafah (9 Dhu al-Hijjah), and the fast of Ashura (10 Muharram). Among many though not all Sunnis, the Mawlid (12 Rabi al-Awwal) and the night of mid-Shaban (15 Shaban) are also observed. The remaining dates are honoured and remembered historically rather than kept as festivals.

Why are some of these dates marked as “traditional”?

Because the sources differ over them. The births and passings of the later Imams — such as Imam Jafar al-Sadiq رضي الله عنه, Imam Musa al-Kazim رضي الله عنه, and Imam Ali al-Rida رضي الله عنه — and of Sayyida Zaynab رضي الله عنها are traditional dates that cannot be firmly established from the historical record. They are included for remembrance and clearly marked, because of their place in the story of the Prophet’s ﷺ family.

Is remembering these dates a Sunni or a Shia practice?

Honouring the memory of the Prophet’s ﷺ household is part of Sunni devotion, as the scholars affirmed. The events listed — Ghadir Khumm, Mubahala, and the days of the Karbala narrative — are all recognised in Sunni historical and exegetical literature. What the Sunni tradition avoids is turning these remembrances into fixed acts of worship without an established basis, or into occasions of sectarian dispute.
