A clear starting point

AL-Naqawa calculates prayer start times from the sun’s position, your city’s coordinates and a selected calculation method. The city dataset supplies location, elevation and a default method; the prayer_time_plus engine performs the calculation. These are calculated start times, rather than a mosque’s Iqamah or Jumuah schedule.

What changes between methods?

Methods may use different twilight angles for Fajr and Isha, a fixed interval for Isha or Maghrib, and small built-in minute adjustments. Asr also depends on the selected shadow rule. The method comparison tool keeps city, date, time zone and Asr settings the same, so you can see the effect of changing a method.

Time zones and daylight saving

A city’s current clock offset is not a reliable offset for every date. AL-Naqawa resolves the city’s IANA time zone for each calculation date, including daylight-saving changes. Times on this site refer to the selected city, even when your own device is in another time zone.

At high latitudes

In some seasons, the sun may not reach the twilight angle used by a method. The engine offers automatic, middle-of-the-night, seventh-of-the-night and twilight-angle fallbacks, or no fallback. A missing event is displayed as unavailable; it is not replaced with midnight. Ask a trusted local mosque which convention it follows.

Choosing settings that make sense for you

Start with the method you usually follow. Check the method name, Asr rule and any individual minute adjustments, especially if you are comparing another timetable. A difference alone does not show that one source is wrong. You can inspect and change all of these settings on the city page.
