For a collection of images showing the Moon's phases see: Phases of the Moon Photo Gallery.

The Phases of the Moon table also shows when an eclipse takes place. An eclipse of the Sun can only occur at New Moon (see: Solar Eclipses for Beginners), while an eclipse of the Moon can only occur at Full Moon (see: Lunar Eclipses for Beginners). In any calendar year there are a minimum of two solar and two lunar eclipses.

If an eclipse of the Sun or Moon takes place on a given date, it is noted by a character next to the date in the Phases of the Moon table. Solar eclipses are indicated as: T=Total, A=Annular, H=Hybrid and P=Partial. Lunar eclipses are indicated as: t=Total, p=Partial, and n=Penumbral.

Solar Eclipses

The following table contains links to a series of web pages covering the 21st Century. Each one summarizes ten years of solar eclipses. Every eclipse has links to a global visibility map, an interactive Google map, tables, and additional information.

        • ART = Argentina Time (= UTC - 3 hours)
        • AST = Atlantic Standard Time (= UTC - 4 hours)
        • EST = Eastern Standard Time (= UTC - 5 hours)
        • CST = Central Standard Time (= UTC - 6 hours)
        • MST = Mountain Standard Time (= UTC - 7 hours)
        • PST = Pacific Standard Time (= UTC - 8 hours)
        • AKST = Alaskan Standard Time (= UTC - 9 hours)
        • HST = Hawaiian Standard Time (= UTC - 10 hours)
          (where UTC = Coordinated Universal Time)

A time zone may have a different name in different countries. Note the difference in hours between a given time zone and Coordinated Universal Time to help in identification.

Accuracy of the Sky Event Almanacs

The goal of the Sky Event Almanacs is to present a wide range of solar system phenomena with reasonable accuracy. In general, events listed to the nearest hour are accurate to ± 30 minutes. Events listed with a precision in hours and minutes (i.e., hh:mm) are typically accurate to ± 5 minutes or less.

The following table gives a more detailed breakdown of the accuracy of times for various astronomical events.

Accuracy of the Sky Event Almanacs
Solstice/Equinox (Earth) ± 0.5 minute
Aphelion/Perihelion (Earth) ± 30 minutes; ± 0.00001 AU
Solar and Lunar Eclipses ± 0.5 minute
Phases of the Moon ± 0.5 minute
Moon at Nodes ± 2 minutes
Apogee/Perigee of Moon ± 5 minutes; ± 5 kilometers
Conjunctions of Moon with Star or Planet ± 10 minutes
Conjunctions of Planet with Planet ± 3 hours
Inferior/Superior Conjunctions (Mercury & Venus) ± 30 minutes
Greatest Elongation (Mercury & Venus) ± 30 minutes
Opposition/Conjunction (Outer Planets) ± 3 hours
Aphelion/Perihelion of Planets ± 30 minutes
