The five daily prayers
Allah made five prayers a duty at set times. The Quran says: 'Indeed, prayer has been decreed upon the believers a decree of specified times' (Surah an-Nisa 4:103). Their times follow the sun: Fajr at true dawn, Dhuhr just after the sun passes its peak, Asr in the late afternoon, Maghrib at sunset, and Isha once twilight is gone. Sunrise is shown too - it marks the end of Fajr's time, and you do not pray then.
Why methods give slightly different times
Dhuhr, Asr, and Maghrib follow the visible position of the sun, so they vary little between methods. Fajr and Isha depend on how far the sun is below the horizon - the twilight angle - which trustworthy bodies have measured a little differently (the Muslim World League, Umm al-Qura in Makkah, ISNA in North America, Karachi, and others). Choose the method your local mosque follows; the differences are usually only a few minutes.
The two views on Asr
For Asr there are two well-known opinions. The majority (Maliki, Shafi'i, Hanbali) hold that it begins when an object's shadow - beyond its shadow at midday - equals the object's own length; the Hanafi school holds that it begins when that shadow is twice the length, which makes Asr a little later. Both are valid; pick the one you follow.
Why praying on time matters
When the Prophet (peace be upon him) was asked which deed is most beloved to Allah, he answered: 'Prayer at its proper time' (al-Bukhari 527). The Quran likewise commands: 'Guard the prayers, and the middle prayer, and stand before Allah devoutly' (Surah al-Baqarah 2:238). Praying within the window Allah appointed is itself an act of obedience - the day is shaped around the prayer, not the prayer squeezed around the day. Scholars teach that each prayer has a preferred earlier portion and remains valid until the next time begins, with Fajr ending at sunrise. Knowing today's exact times for your own city is what makes that guarding practical: you can plan work, travel, meals, and sleep around the five appointments rather than discovering them too late. That is the whole purpose of a prayer timetable - not information for its own sake, but praying each prayer inside its time, the way it was decreed.
Using this tool day to day
Set your location once - search any city in the world or use your device's location; either way the coordinates stay on your device and are never sent anywhere. Then choose the calculation method your mosque follows and your Asr view, and the tool shows all five prayer times for today in that city's own timezone, with sunrise, a live countdown to the next prayer, and a progress ring for the current interval. The monthly timetable lists the whole month at a glance and prints cleanly if you prefer paper on the fridge or the masjid noticeboard. One tap exports the month as a calendar (.ics) file for your phone or computer calendar, and you can opt in to a notification at each prayer time while the page is open. Travellers: because a searched city carries its own timezone, the times you see are always that city's local clock - check tomorrow's Fajr for the city you land in before you fly.
