Understanding prayer times
Knowing the source and purpose of a time helps you plan a visit responsibly.
Start times versus congregation times
Aladhan provides calculated prayer start times for geographic coordinates. A masjid's iqamah schedule may be later, and Friday Jummah can have multiple sessions. Calculations should not be presented as that mosque's timetable.
Why calculation methods differ
Methods use different parameters, particularly for Fajr and Isha. masjid.si lets you choose the method. Confirm the appropriate local method with your mosque; we do not make religious recommendations.
Timezone and date
Times refer to the chosen location's local date and timezone, not necessarily your device's timezone.

Frequently asked questions
Are calculated prayer times the mosque's congregation times?
No. Calculations estimate prayer start times for a location. A mosque sets its own iqamah and Jummah arrangements, which you should confirm directly.
Why do prayer-time apps sometimes disagree?
Calculation method, coordinates, date, timezone and high-latitude adjustments can affect results. Ask your local mosque which timetable and method it follows.
Which timezone is shown on masjid.si?
Prayer times refer to the chosen location's local date and timezone, which may differ from your device's timezone. They are sourced from Aladhan.
