Saudi Arabia will observe Eid Al Adha on July 9, after sighting the crescent moon in Dhu Al Hijjah, the twelfth and final month in the Islamic calendar.
As reported by Arab News, Eid Al Adha will thus fall on July 9, the tenth day of Dhu Al Hijjah.
Saudi Arabia also announced July 8 to be the day of Arafat, the ninth day of Dhu Al Hijjah and one of the holiest days in the Islamic calendar.
On that day, Muslims performing Hajj to Mecca flock to the mount of Arafat. Muslims believe that Prophet Muhammad gave one of his sermons in the final days of his life on the holy site.
Pilgrims usually spend the entire day during Arafat saying their afternoon prayer (Asr) and reciting the Quran.
The International Astronomical Centre predicts that most countries will celebrate Eid Al Adha on Saturday, July 9.
Meanwhile, a handful of countries, including Morocco, are expected to celebrate Eid Al Adha on July 10.
