The city-wide reference
Each city page uses a city-wide reference that combines the local time zone, the selected calculation method, and the core geographic coordinates for that city.
That reference is what drives Fajr, Dhuhr, Asr, Maghrib, Isha, and sunrise, which is why timings can vary from one city to another even inside the same country.
Why timings change every day
Prayer times change as the sun’s position changes throughout the year. Daily differences in Fajr, Maghrib, and Isha are therefore normal, and seasonal shifts are expected.
Small differences can also appear between timetables when a different local calculation method or reference is used.
Mosque details and iqama data
Mosque pages may include iqama timings and Friday khutbah or prayer timings. When a mosque has not provided confirmed data yet, the page may show a reference estimate based on the wider city context or previously available information.
That is why a mosque update submitted from the mosque page itself remains the best source when iqama or Friday timing precision matters.
