Eclipse Almanac 2021 to 2030 is a concise reference for every eclipse of the Sun and the Moon over a 10-year period. This compendium identifies when and where each of these events will be seen. Particular details about each eclipse are included, as well as a 25-year table looking further into the future.

Section 1 presents solar eclipses including an explanation of why they occur, types of solar eclipses (partial, annular, and total), and the visual appearance of each. Global maps depict the geographic regions of visibility of each of the 22 solar eclipses.

Section 2 covers lunar eclipses with an explanation on why they occur, types of lunar eclipses (penumbral, partial, and total), and the visual appearance of each. Detailed figures illustrate each of the 22 lunar eclipses including the Moon's path through Earth's shadows, and a map identifying the geographic regions of visibility of every eclipse.

Section 3 lists the date and time of the Moon’s phases over the decade. New Moon and Full Moon phases coinciding with solar and lunar eclipses are identified.
