Astronomically the first day of Eid has been revealed.

:: Ramadan is calculated to end on Saturday, July 24 – the same weekday as it began.

Sunday will therefore be the first day of Eid al-Fitr, a member of the Arab Union For Astronomy and Space Sciences, Khaled Al Za’aq, told Al Arabiya.

Eid al-Fitr officially starts when the new moon is spotted in the sky, making the Eid holiday different around the world.

The celebrations begin when the fasting month of Ramadan ends and the following month of Shawwal begins.

Traditional greetings during the Islamic holiday begin with “Eid Mubarak,” which means “Have a blessed Eid.”

Families gather together to pray, share meals and mark an end to the holy fasting month of Ramadan.
