The following table gives the date and time of important astronomical events for May 2016. The time of each event is given in Greenwich Mean Time or GMT (a.k.a. Universal Time or UT). To convert GMT to Eastern Standard Time (EST) just subtract 5 hours. To convert GMT to other time zones, visit Time Zones. Some of the astronomical terms used in the calendar are explained in Definitions.
Of special note this month is a rare transit of Mercury across the Sun’s disk on May 9.
