Overview
- After its Nuit du doute combining lunar observation with astronomical data, the Grande Mosquée de Paris announced Ramadan would begin on Wednesday, February 18, joined by federations including Musulmans de France, Foi et Pratique and FFAIACA.
- The CFCM, relying solely on astronomical calculation, fixed the first day to Thursday, February 19, and reiterated its decision, with mosques such as Metz and Strasbourg following Thursday and Lyon opting for Wednesday.
- Different national authorities reached different start dates as well, with Saudi Arabia, Qatar and the UAE beginning Wednesday, while Algeria, Egypt, India and Belgium marked Thursday.
- Supporters of calculation say Aïd el‑Fitr would fall on Friday, March 20, whereas observation-based bodies will confirm the festival date after a final moon check.
- Practical effects are immediate, with calls for authorities to ensure security at Muslim places of worship and fasting timetables varying by location, generally running slightly longer in northern and northeastern cities.
