High precision prayer time library

Adhan is a well tested and well documented library for calculating Islamic prayer times. All astronomical calculations are high precision equations directly from the book “Astronomical Algorithms” by Jean Meeus.

Adhan is made publicly available to provide a well tested and well documented library for Islamic prayer times to all developers. We accept feature contributions provided that they are properly documented and include the appropriate unit tests. We are also looking for contributions in the form of unit tests of of prayer times for different locations, we do ask that the source of the comparison values be properly documented.
