A calendar calculation predicts Eid al-Adha, or the Festival of Sacrifice, to occur on June 28, with the Day of Arafat occurring on June 27.
Especially for the Islamic lunar calendar, the sighting of the new moon determines the start of the Islamic months. New moons are predicted using astronomical calculations and telescopes, among other methods. After the conjunction, Sunday, June 18, will bring the new moon of Dhul-Hijjah, the Islamic month’s beginning.
Furthermore, the new moon is expected to appear between 7 and 44 minutes after sunset on Monday, June 19, 2023, marking the beginning of Dhu al-Hijjah 1444 Hijri. Muslims must make a pilgrimage to Mecca at least once during their lifetimes during the Hajj season.
Dhu al-Hijjah is also the month Eid al-Adha, also known as the Festival of Sacrifice, is celebrated. During this festive occasion, Muslims worldwide gather for communal prayers and perform acts of generosity, including sacrificing an animal, usually a sheep.
In addition to the Day of Arafat, which occurs on June 27, Eid al-Adha falls on June 28. The month of Dhu al-Hijjah holds great significance for Muslims, providing a time for spiritual reflection and renewal of faith.
