Islamic nations across the globe are preparing to look for the crescent moon on Monday, June 15, to mark the start of the Hijri New Year 1448 and the holy month of Muharram. Experts from the UAE’s Astronomy Centre suggest that while visibility varies by location, most Islamic countries will likely observe the new month beginning on Tuesday, June 16. While those in parts of the Americas and western Africa may spot the crescent with the naked eye, observers in central and western Asia, as well as much of Europe and Africa, will likely require a telescope to catch the slim lunar sliver.

The ability to sight the moon depends on precise scientific criteria, including the moon's age and the timing of its setting relative to the sun. The Astronomy Centre notes that for the crescent to be visible, it must typically be at least 15 hours and 33 minutes old and remain in the sky for at least 29 minutes after sunset. Cities like Abu Dhabi and Makkah fall within the telescope-only visibility range, while locations like Rabat, Cairo, and Amman might see it with the naked eye if weather conditions are perfect. Conversely, regions like Jakarta are expected to miss the sighting entirely due to the moon's insufficient age and lag time.

In the UAE, the government has already announced that Monday, June 15, will be an official public holiday for both private and federal sectors. This decision ensures a long weekend for residents, with some employees in Sharjah benefiting from a four-day break due to their extended weekend schedule. Whether the new year officially begins on Tuesday or Wednesday, this holiday provides a significant opportunity for residents to observe the start of the Hijri calendar.
