Local Islamic authorities in Senegal report that the crescent moon marking the start of Dhul Hijjah 1447 was not visible over the country on May 17, 2026, prompting adjustments to the religious calendar. The confirmation of Tabaski’s date follows rigorous observations conducted by the National Observatory for Islamic Crescents (CONACOC).

Consequently, Arafat Day will be observed on Wednesday, May 27, 2026, while Tabaski will take place on Thursday, May 28, 2026, for Senegalese Muslim communities. Each year, variations in Tabaski dates across different nations stem from differing lunar observation methods, with some countries prioritizing local sightings over global astronomical calculations.
