Multiple nations have officially declared Thursday, February 19, 2026 as the commencement date for Ramadan following sophisticated astronomical calculations that determined the crescent moon would be impossible to sight on the anticipated evening of February 17. Turkey and Singapore join Oman in coordinating the holy month’s start through scientific methodology rather than traditional visual observation.
The Turkish Presidency of Religious Affairs released a comprehensive analysis indicating that crescent moon visibility would be impossible on Tuesday, February 17 from any location throughout the Arab and Islamic world, including the American continents. This determination holds particular significance as Turkey’s calculations incorporate regions experiencing nighttime simultaneously with Turkish territories.
Concurrently, the Islamic Religious Council of Singapore, under the leadership of Singapore’s Mufti, issued an identical declaration based on their astronomical assessments. Both religious authorities concluded that the crescent moon would only become visible on Wednesday, February 18, thereby establishing Thursday, February 19 as the first day of Ramadan fasting.
This coordinated announcement reflects the growing trend among Muslim-majority nations to employ advanced astronomical science alongside traditional religious practices for determining Islamic calendar dates. The methodology represents a fusion of technological precision with religious observance, ensuring unified celebration across participating nations while maintaining astronomical accuracy.
The announcements come as Muslim communities worldwide prepare for the holy month, with several countries already implementing Ramadan-specific arrangements including adjusted work schedules and special religious preparations.
