Which Eid al-Adha-related Hajj day is also called Yawm an-Nahr?

The Hajj day called Yawm an-Nahr is 10 Dhu al-Hijjah, the day of Eid al-Adha.

Yawm an-Nahr means the Day of Sacrifice. It follows the Day of Arafah, when pilgrims gather on 9 Dhu al-Hijjah for the central vigil of Hajj. On the 10th, pilgrims leave Muzdalifah for Mina and perform the first major stoning at Jamrat al-Aqabah.

The day’s rites also include sacrifice for pilgrims whose Hajj type requires it, shaving or trimming hair, and entering a first stage of release from ihram. Pilgrims then perform Tawaf al-Ifadah in Mecca, an essential circumambulation of the Kaaba. The order and practical timing can vary within established rulings.

A common mistake is to identify Yawm an-Nahr with the 9th, which is Yawm Arafah, or with the later Days of Tashriq. Globally, Eid al-Adha begins on this 10th day, although the corresponding Gregorian date changes annually because the Islamic calendar is lunar.
