The sighting of the new moon defines the lunar months of the Islamic calendar, including Ramadan, Eid, and Muharram.
The Pakistan Space & Upper Atmosphere Research Commission (Suparco) uses scientific methods, astronomical calculations, and advanced technology to forecast the appearance of the Ramadan and Shawwal crescents.
Astronomically, the Shawwal moon is likely to be visible on March 30, suggesting that Eid ul Fitr will most certainly fall on March 31, 2025.
