Director of the International Astronomical Center, Engineer Mohammed Shoukat Ouda, in a statement said that most Islamic countries will be searching for the crescent moon on the month of Dhu al-Qa’ada, 1444 AH, Addustour reported.

He noted that that the moon will be difficult to observe using a telescope from the central and western parts of the Islamic world. Therefore, it is expected that Monday, June 19, will be the first day of the month of Dhu al-Hijjah in many countries, and Tuesday, June 27, will be the day of Arafah, and Wednesday, June 28, will be the first day of Eid al-Adha.

Visibility of the moon around the world
Regarding the visibility of the crescent moon on Sunday, June 18th, in some Arab and Islamic cities, the surface calculations for the moon's disappearance after sunset are as follows:

In Jakarta, the moon will set 7 minutes after sunset, with an age of 6.5 hours.

 In Abu Dhabi, the moon will set 29 minutes after sunset, with an age of 12.4 hours. Visibility in Jakarta and Abu Dhabi is not possible even with a telescope.

In Riyadh, the moon will set 31 minutes after sunset, with an age of 13 hours.

In Amman and Jerusalem, the moon will set 37 minutes after sunset, with an age of 13.8 hours.

In Cairo, the moon will set 36 minutes after sunset, with an age of 14 hours.

In Rabat, the moon will set 44 minutes after sunset, with an age of 16.2 hours.

Visibility in Riyadh, Amman, Jerusalem, Cairo, and Rabat is possible only with a telescope and is challenging in the eastern and central regions. It requires a very clear sky for observation.

To understand the meanings of these numbers, it should be noted that the shortest time for the crescent to be visible to the naked eye is 29 minutes, while the youngest age for the crescent to be visible to the naked eye is 15 hours and 33 minutes. It is not enough for the moon to exceed these values in age and visibility.

The visibility of the crescent is related to other factors, such as its angular distance from the sun and its distance from the horizon at the time of observation.
