SkyAlmanac is a simple astronomy application. Rise and set times of sun and moon, the so-called "golden Hours", "blue Hours", moon phases and equinoxes are calculated and displayed.

Place and calculation time can be freely selected.

The underlying calculations are based on well-known models, for example VSOP87 for the positions of the sun or ILE (Improved Lunar Ephemerides) for the moon.
