How SalahTimeNow calculates prayer times
There is no single calculation convention used by every Muslim community worldwide. SalahTimeNow therefore makes the location, timezone, fiqh, calculation method and high-latitude setting visible and configurable.
What goes into a calculation?
Daily prayer times are calculated from the selected location’s latitude and longitude, the local date and IANA timezone, the chosen calculation convention, the selected fiqh and—where relevant—the selected high-latitude rule. Optional minute adjustments can also be applied in Settings.

Frequently asked questions
Why can prayer times differ between websites or mosques?
Different recognised calculation methods use different parameters, and local mosques may apply their own adjustments. SalahTimeNow shows the selected method and lets you change it.
What does the Fiqh selector do?
Shafi and Hanafi keep your chosen Sunni calculation convention while changing the Asr juristic rule. Jafari switches to a Shia Ithna-Ashari calculation convention, where Fajr, Maghrib, Isha and midnight parameters can also differ.
What happens at high latitudes?
At locations where twilight behaves unusually, a high-latitude adjustment rule may be needed for Fajr and Isha. SalahTimeNow exposes this setting rather than hiding it.
Is the Hijri date universal?
Hijri dates can vary by calendar convention and local moon-sighting practice, so the displayed date should be treated as a calculated reference rather than a claim about every local authority.
Should I follow my local mosque?
If your mosque or local religious authority publishes prayer or congregational times that you follow, use those local times. SalahTimeNow is a calculation utility and does not replace local religious guidance.
