From the developer:
LunaCal was written to predict the visibility of the Moon as a tool for observational lunar calendars. The main purpose of the software is to aid in the observation of the crescent Moon but is equally applicable to the limits of observation of other bright heavenly bodies. In addition it provides information about the location phase and magnitude also regarding the Sun, planets and bright stars.
