Prayer times
Same city. Different prayer times. Why?
A few minutes can have a reason. Understand calculation methods, Asr settings, and your local mosque’s timetable.
Start with the settings, not the clock
Two prayer apps can show different times while both are calculating for the same city. Before deciding which timetable to follow, compare the date, coordinates, timezone, calculation method and Asr setting. These are separate inputs, and changing any one of them can change the result.
Athan for All displays the selected location and timezone beside the timetable. Open Calculation settings to see the method and Asr convention. The website and mobile app use the same calculation code, so matching their settings is the first step when comparing them.
Fajr and Isha depend on twilight conventions
Prayer-time calculation libraries offer several named conventions for estimating dawn and night. Many use angles of the sun below the horizon; some use a fixed interval for Isha. A convention with a different angle or interval can produce a different result even when the coordinates are identical.
The regional suggestion in Athan for All is a starting point, not a declaration that a method is universally correct for everyone in a country. Choose the method used by your local community when you know it. In places with unusual summer twilight, high-latitude rules also affect calculated times.
Asr has its own setting
The Asr selector is independent of the named calculation method. The standard setting uses the convention commonly associated with the Shafi, Maliki and Hanbali schools; the Hanafi setting produces a later Asr time. Choosing a regional method does not settle that separate preference.
If only Asr differs between two timetables, compare this setting first. If Fajr and Isha differ, compare the twilight method and high-latitude handling as well.
City centres are an approximation
A city result uses approximate coordinates for that place. Device location, when permitted, calculates for your actual coordinates. A large metropolitan area can span enough distance for the distinction to matter. The displayed timezone handles daylight-saving changes; your browser’s own timezone does not replace the selected city’s timezone.
Mosques may publish adjustments or congregation times in addition to the start of each prayer. The website does not supply iqamah times. Compare like with like, and ask your mosque which timetable and settings they recommend.
When the calculation is unavailable
At some latitudes and dates, the required solar events cannot be calculated with the available settings. Athan for All shows an unavailable message instead of inventing a time. Consult a local mosque for the timetable appropriate to that situation.
The Hijri date shown beside the schedule is an approximate calendar display. Local observance may differ. It should not be used on its own to establish the beginning of Ramadan or Eid.
