From the developer:
NightCal is a simple, practical tool for basic observation session planning. It is designed to produce a monthly calendar telling you when it gets dark, when the Moon rises and sets and what the Moon should look like when it does make an appearance. It also provides data on the elongation of the inferior planets and a quick aide mémoire for planetary conjunctions.
