Search frequently asked questions for latitude

Prayer times are determined by the position of the sun and are calculated using astronomically measurable values.

For countries above 48 degrees latitude, including Britain, Fajr and Isha times may require estimation during certain months of the year.

This is because twilight can continue between sunset and sunrise, meaning the sun may not go far enough below the horizon for true night to occur.

In these situations, Salah Times uses the 1/7 rule method by default for the UK to calculate Fajr and Isha times. You can also change this to another high latitude method if needed.

Prayer times are calculated using established formulas that take into account factors such as the latitude and longitude of a location.

Because different organisations, websites, and mosques may use different calculation methods or settings, prayer times can vary slightly between sources.

In high latitude locations, these differences can become more noticeable, especially during the summer months when Fajr and Isha times are harder to calculate precisely.

For this reason, high latitude methods are used to provide a practical approximation for these prayer times.

Fajr and Isha times can vary depending on the calculation settings used.

Please check whether changing the prayer calculation method or high latitude method gives results closer to the timetable you are comparing against. These settings usually have the biggest effect on Fajr and Isha times.

Different websites, apps, and local mosque timetables may use different formulas, angles, and calculation settings. Because of this, prayer times from Salah Times may not always match another source exactly.

Prayer times can differ because different mosques, websites, and organisations may use different calculation methods and settings.

The biggest differences are usually seen in Fajr, Isha, and Asar times. Fajr and Isha are affected by the twilight angle and high latitude method, while Asar is affected by whether the Shafi or Hanafi method is used.

Your local mosque may also use its own timetable, local observation, or fixed Jamaat times, which may not exactly match calculated prayer times.

If you want Salah Times to match another timetable more closely, try changing the prayer calculation method, high latitude method, or Asar method for your location.

High latitude methods are used in places where Fajr and Isha can be difficult to calculate accurately during certain times of the year.

This usually affects countries that are far north or far south, where twilight may last for a long time during the summer months.

For the UK, Salah Times can use the 1/7 rule method by default. However, you can change this to another high latitude method if needed.

If you are unsure which method to use, compare the results with a trusted local mosque timetable and choose the setting that gives the closest match.

Yes, you can change the prayer time settings for your selected location.

These settings may include the prayer calculation method, high latitude method, and Asar method.

Changing these settings can affect the calculated prayer times, especially Fajr, Isha, and Asar.

If your prayer times do not match a local mosque or another trusted timetable, adjusting these settings may help you get a closer match.
