How eid al adha date is calculated?

Answer 1

Eid al-Adha is calculated based on the Islamic lunar calendar, specifically occurring on the 10th day of Dhu al-Hijjah, the final month of the calendar. The exact date varies each year in the Gregorian calendar due to the lunar year being about 10 to 12 days shorter. The sighting of the moon plays a crucial role in determining the start of Dhu al-Hijjah, and thus the date of Eid al-Adha. Different countries may announce the date based on local moon sightings or astronomical calculations.
