Why a new calculator?

Ramadan this year falls into a period where true Fajr time can still be observed at high latitudes. However, many of the current prayer time tables, instead of giving this correct time, give manipulated times for Fajr during the entire period from March to September. In Scandinavia or northern Canada, the difference between the true and the manipulated time can be up to an hour or more.

If you want to make sure to begin your fast before the true dawn, you must use a prayer time table that gives the true times. These are provided in the Birka prayer time table.

Birka comes with ample documentation in English and Swedish, to support its method. Please take a tour and you will soon realize the advantages of using this new program.

  •   IslamicFinder
  •   Rabita (Islamiska Förbundet i Sverige) and all its sub-organisations
  •   Islamguiden
Unfortunately, prayer time tables in many mosques come from one of these sources.

If the prayer time table in your local mosque does not agree with any of the reliable time tables mentioned above, it would be in the interest of Muslims to have it changed.

Birka on your website

The Birka calculator gives tables for 1 day as well as for an entire month. It can be customized to suit any webpage, with the preferred location, defaults settings, colors and layout. If you drop a mail stating your requirements before the beginning of Ramadan 2009, you will inshaAllah receive a link to your own personalized calculator.
