I have written a calendar programm in VB4.
Now I want to add the moonrise and moonset function for any date.
To do this for a certain date, one must know basically 3 figures:
Latitude, longitude and the Time zone of the place.
All theese are of course easily known.
Now, does anyone know the algorithms or the way to computate the moonrise/set times?
(Or at least the Right Ascension and Declination of the moon?)

This link seems to have the formulas you need:

It is not code, just formulas.
