Prayer Time Accuracy and Limits
A clear explanation of why timetables can differ and when local confirmation matters.
Prayer times depend on the city location, timezone, calculation method, and Asr setting. A small difference can appear between large metro areas or between calculation methods.
Iqama, Jumuah, and Ramadan announcements remain connected to the local mosque or authority.
When to Check Locally
Check the mosque timetable for iqama, congregation, and Friday khutbah, and follow the local authority for Ramadan and Eid announcements.
City or timezone corrections should be handled as data updates supported by a clear source.
