Saudi Arabia has announced that the annual Muslim feast of Eid al-Adha 2016 will begin on Monday, September 12, after religious authorities in the kingdom failed to sight the Moon on September 1.
Next Saturday marks the first day of the Dhu al-Hijjah lunar month and Eid al-Adha always falls on the 10th day of that month.
The Eid al-Adha is Islam’s holiest festival celebrated annually around the world and an official holiday in Muslim-majority countries.
In the Islamic calendar, Eid al-Adha occurs on the 10th day of the Dhu al-Hijjah and is also the third day of the Hajj pilgrimage in Mecca.
