Question 1

How are prayer times calculated?

Accepted Answer

Prayer times are determined by the sun's altitude angle at your location. The tool uses astronomical algorithms to calculate the times for Fajr (dawn), Sunrise, Dhuhr (noon), Asr (afternoon), Maghrib (sunset), and Isha (night) based on latitude, longitude, and date. Different Islamic institutions use slightly different sun angles for Fajr and Isha, so multiple calculation methods are provided.

Question 2

Which calculation method and school should I choose?

Accepted Answer

Calculation methods are typically chosen based on local authoritative institutions for your country or region (e.g., ISNA for North America, Umm al-Qura for Saudi Arabia). In Asr schools, the Hanafi school's Asr time is slightly later than that of Shafi'i and other schools. Please choose according to the madhhab you follow, and the results will be adjusted accordingly.

Question 3

Are the times accurate? Will my location be uploaded?

Accepted Answer

The calculation results are based on standard astronomical algorithms, highly consistent with mainstream prayer time tables, and can be used for daily reference. Location is provided by the browser after your authorization; latitude and longitude are only used locally in the calculation and are not uploaded to any server. You can also manually enter coordinates.
