Eid ul Azha – one of the two major Islamic festivals that Muslims celebrate every year – is likely to fall on June 29 in the middle eastern region and a day later in Pakistan, according to experts.

Egypt’s National Research Institute of Astronomy and Geophysics has given a possible date for much of the Arab world, especially the mid-eastern countries.

The Islamic month of Dhu al-Qadah year 1444 AH will begin Sunday, May 21, Dr. Jad Jean El Kazzi, head of the Institute of Astronomy and Geophysical Research said.

This month can be 29 days, according to astronomical calculations, in that case, there is a possibility that Eid ul Azha will be celebrated on June 29.

Dhu al-Qadah’s crescent is likely to be seen at 5:54 pm on Friday, 29 Shawwal (May 19) according to Cairo local time.

However, in some Arab and Islamic countries, a new crescent may not have been born after sunset. Because the moon will set 3 minutes before the sunset in Makkah, while the new moon in Cairo will remain on the horizon one minute after sunset.

If the calculations are correct, then Pakistan would observe the first day of Eid al Azha on June 30.
