About Jammap
From the Jammap team. Updated 4 Oct 2026.
What Jammap is
Jammap is a map of Friday prayer (Jumu’ah) times. Open it and it shows the mosques near you, when each one’s khutbah and prayer start, how far away they are, and whether the gathering meets the conditions of your school of thought. Today this site lists 3,897 mosques with a time read from their own page, in 42 countries.
How a time gets on the map
- Read from the mosque itself. We read each mosque’s Friday time from its own website or its own prayer-time board, and link to that page beside the time.
- The words are kept. We store the exact words the time was read from, so it can always be checked again.
- Checked against the sun. A Friday time must fall after the sun’s noon (Dhuhr) and well before Asr. A time that doesn’t is held back.
- Dated. Each mosque page says when its time was last checked, and every day a sample of times is read again against their pages.
The mosque pages on this site only show times read from the mosque’s own page. Times copied from directories, and times read from social media posts, are not on them. In the app, a time that came from a directory is marked as such.
If your mosque’s time is wrong
Times change: summer and winter, Ramadan, a new hall. If a time on Jammap is wrong, email us with the mosque’s name and a link to the page where you publish your Friday times, and we’ll put the right one on the map. In the app, you can also tap “This time is wrong” on the mosque.

You can use Jammap without an account. To find the mosques near you, the centre of the map is sent to us and isn’t stored; the privacy policy has the rest. You can also see how to delete your data.
