Why your app says 5:12 and the masjid says 5:29
Two correct prayer timetables can disagree, because Fajr and Isha depend on a chosen sun angle and Asr on a shadow rule that differs by school. This room explains the settings instead of telling you a time. We publish no timetable of our own — follow your local masjid.
Why the times differ

Read →If your Asr looks “early”, that is usually a setting, not a bug. Asr begins when an object’s shadow equals its own length in the Maliki, Shafi’i and Hanbali schools, and twice its length in the Hanafi school. Fajr and Isha depend on how far below the horizon the sun has to be — 18°, 15° and others are all in use by different bodies. Neither is a bug and neither is the “correct time”: they are different defensible choices, and your app almost certainly made one for you without saying so.

🌒Central Hilal CommitteeOne of the bodies that actually announces the month, rather than a blog guessing. US
Visit →Calculation against sighting is a live dispute between qualified bodies — and so is local against global sighting. They produce genuinely different dates for Ramadan and both Eids, which is why your family abroad may be a day out. Any Hijri date you see anywhere, including in a calendar app, is a calculated estimate until the month is announced. Follow your local masjid, which is what the announcing bodies themselves say.
