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. The calendar can be printed so that you can stick it on your notice board at home or in your observatory or it can be saved as a graphics file for inclusion in newsletters or for publishing on the web.
