Moonset -- from Eric Weisstein's World of Astronomy

The time at which the Moon first sets below the horizon. The rising and setting times are dependent on latitude, but occur later each day by an average of 1/29.531 of a day (about 49 minutes). However, the actual time difference between risings/settings on consecutive days can be

minutes greater of less over the course of the year. The time of moonset closest to a given date can be determined using MoonSet[neardate] in the Mathematica application package Scientific Astronomer.
