This astronomy calendar of celestial events contains dates for notable celestial events including moon phases, meteor showers, eclipses, occultations, oppositions, conjunctions, and other interesting events. Most of the astronomical events on this calendar can be seen with unaided eye, although some may require a good pair of binoculars for best viewing. Many of these events and dates used here were obtained from the U.S. Naval Observatory, the NASA/Goddard Space Flight Center, and The Old Farmer's Almanac.
