When is Ramadan 2026, and how is the moon sighted?

Ramadan in 2026 is predicted to begin in Mecca, Saudi Arabia, on either February 18 or 19, depending on the sighting of the new moon. The start of Ramadan is determined by the Islamic lunar calendar, which relies on the sighting of the crescent moon. Muslim-majority countries, including Saudi Arabia, depend on testimonies of moon sighters, which are then reviewed by the Supreme Court to determine the start of the holy month. For the moon to be visible, it must set after the sun, and astronomers consider factors like elongation, altitude, and lag time. If the moon is sighted on the evening of February 17, fasting begins on February 18; otherwise, it starts on February 19. Other countries may follow their own moon sightings or use astronomical calculations.
