Saudi media announced that Friday is the first day of the month of Dhu al-Hijjah for the Hijri year 1440, and therefore the day will stand at Arafah on Saturday, 10 August.
Saudi media quoted the Observatory of the University of Majmaa Al-Falahi in Hawat Sudair (one of the most important observatories in Saudi Arabia) as saying that Hilal was the month of Dhu'l-Hijja on Thursday evening, and that Eid al-Adha would be on August 11.
The Qatari calendar said that Friday is the month of Dhu al-Hijjah.
A statement issued by the Dar said that Hilal of Dhu al-Hijjah will be born on the morning of the vision day of August 1, at 06:13 Doha time, meaning that there is a chance for the crescent of 12 hours and seven minutes before the next sunset, and this allows the crescent to move Enough distance away from the sun so that it lasts about half an hour after sunset.
The countries of the Arab world will differ in the period of survival of the crescent after sunset, but they will all revolve around 30 minutes, increasing as we travel westward to the Maghreb.
This slight difference means that visibility will be achieved for almost all Arab countries, indicating that the Arab states will agree together in the middle of this year.
According to a statement issued by the Center for International Astronomy, the dawn of the month of Dhu al-Hijjah after the sunset of the first of August easily through telescopes in the Arab world, and the people of the Americas North and South, will be able to see the naked eye.
