The first day of Hijri month Dhul-Hijja 1438H will be on August 23, so Eid al-Adha this year will be on September 1, according to QCH.
“According to accurate calculations the new crescent of Dhul- Hijja 1438H will born on 29 Dhul-Qa’da (August 21) at 9.31pm,” QCH director Dr Mohamed al-Ansari and astronomer expert Dr Beshir Marzouk said in a statement yesterday.
The time set of the moon will be before sunset time over Doha sky by 10 minutes on 29 Dhul-Qa’da (August 21), while the time set of the moon will be before sunset time over the sky of two holy mosques Makkah and Medina and over all Gulf countries by (8 – 11 minutes).
The new crescent will be impossible to view by astronomical telescopes or naked eye over Doha sky and all Arabic countries sky on this night, because it will bear after sunset time over Doha sky and most of Arabic and Islamic countries sky.
Therefore, the Hijric month “Dhul-Qa’da 1438 H” will be end on August 22, and the first of “Dhul- Hijja 1438H” will be on August 23.
The Arafat day will be on August 31, Dr Marzouk added.
Eid Al-Adha is always on the same day of the Hijric calendar (10th of Dhul- Hijja), while the date on the Gregorian calendar varies from year to year.
The Gregorian calendar is a solar calendar while the Hijric calendar is a lunar calendar. This difference means Eid Al-Adha moves in the Gregorian calendar approximately 11 days every year.
