CalSky

CalSky are programs for calculating astronomical events available online on the Internet ( www ) .

history

CalSky was founded in 1991 by the Swiss engineer Arnold Barmettler.

With the help of CalSky, the Swiss economist Hanspeter Götte succeeded in locating the long sought-after star of Bethlehem .

Features

CalSky is available in German and English and includes a variety of calculation options. It is a tool for calculating the rising and setting times of the stars, the transition calculations for the sun , moon, planets and other celestial bodies such as satellites and the international space station . The program also offers an astronomy calendar.
