All times and dates on this page are in Universal Time or UT. This astronomically derived time system is colloquially referred to as Greenwich Mean Time or GMT. To learn more about UT and how to convert UT to your own local time, see Time Zones and Universal Time.
The predictions below are drawn from the Five Millennium Canon of Solar Eclipses and the Five Millennium Canon of Lunar Eclipses (Espenak and Meeus). Unlike the pages for 1996 through 2014, this page is not an Observer's Handbook article: it carries the catalog predictions and links to the detailed eclipse resources, without the accompanying figures, data tables, and commentary.
