Ramadan 2026 in Saudi Arabia, UAE, Qatar and many Islamic countries is expected to begin on Thursday, February 19. The month starts based on the sighting of the new crescent moon at the end of Sha’ban. Experts from the International Astronomy Centre and Emirates Astronomy Society predict the moon will be very hard to see on Tuesday, February 17. In the UAE, the moon is expected to set one minute before the sun on that day, making crescent sighting nearly impossible. Because of this, February 18 will likely be the last day of Sha’ban, and fasting will start the next day. This view is based on scientific calculations of moon age and positioning, aligned with international crescent visibility rules. However, some Muslim communities in South Asia and North Africa may start Ramadan on Wednesday, February 18 if local sightings differ. Religious and moon-sighting committees in the UAE will confirm the start date following the crescent sighting. Then, mosques, schools, and government bodies will announce fasting schedules and prayer times. Ramadan fasting will last about 30 days, with Eid al-Fitr expected around March 20, 2026, but final date depends on the next moon sighting. This year’s Ramadan attracts attention as it falls earlier in the Gregorian calendar and the crescent moon’s close position to the sun reduces visibility. Scientists suggest relying on astronomy when moon sightings are very unlikely. The mix of traditional practices and modern science guides decisions. Most Muslims in the UAE and much of the Arab world will likely start fasting on February 19. Some regional variations remain possible. Ramadan 2026 promises to be a solemn and spiritual month, uniting faith and science under the night sky.
