The International Astronomy Center announced that "for the countries that will look for the crescent moon on Monday, April 8, its visibility that day is impossible due to the moon setting before the sun and the conjunction occurring after sunset, and thus these countries will complete the month of Ramadan with thirty days, making Wednesday, April 10, the day of Eid Al-Fitr in those countries." The statement continued: "As for the countries that will look for the crescent on Tuesday, April 9, the sighting of the crescent that day is possible using a telescope from the eastern part of the world and from South Africa, and it is challenging to see with the naked eye from Central Asia and Central Africa, while the crescent can be seen easily with the naked eye from Western Asia, North Africa, most of Europe, and most of the Americas. Therefore, it is expected that most of these countries will announce the sighting of the crescent on that day, making Wednesday, April 10, Eid Al-Fitr for them as well. It is not excluded that both India and Bangladesh might announce no confirmation of the crescent sighting on Tuesday, leading to Thursday, April 11, being their Eid Al-Fitr."
He added: "Regarding the crescent's position on Tuesday, April 9, in some Arab and Islamic cities, the surface calculations for the crescent at sunset are as follows: In Jakarta, the moon sets 29 minutes after sunset, with an age of 16 hours and 58 minutes, and visibility is possible using a telescope. In Abu Dhabi, the moon sets 51 minutes after sunset, with an age of 19 hours and 35 minutes. In Riyadh, it sets 53 minutes after sunset, with an age of 20 hours. In Amman and Jerusalem, it sets 60 minutes after sunset, with an age of 20 hours and 38 minutes. In Cairo, it sets 59 minutes after sunset, with an age of 20 hours and 47 minutes. In Rabat, the moon sets 69 minutes after sunset, with an age of 22 hours and 57 minutes. The crescent can be sighted with the naked eye in Abu Dhabi, Riyadh, Amman, Jerusalem, Cairo, and Rabat, assuming clear atmospheric conditions."
The International Astronomy Center published two maps showing the path of the moon and the regions where it can be seen, stating in its report: "Viewing the crescent is impossible from the areas colored in red due to the moon setting before sunset and/or due to the surface conjunction occurring after sunset. Viewing the crescent is possible only using telescopes from the areas colored in blue. Viewing the crescent is possible using a telescope from the areas colored in pink, and it may be seen with the naked eye under completely clear atmospheric conditions and with experienced observers. Viewing the crescent is possible with the naked eye from areas colored in green. Crescent sighting is not possible with the naked eye or with telescopes from uncolored areas, despite the moon setting after sunset and the occurrence of surface conjunction before sunset, due to the low illumination of the crescent and/or its proximity to the horizon. It should be noted that the shapes indicate the possibility of seeing the crescent in regions between latitudes 60° North and 60° South."
