2015 Phases of the Moon
Pacific Standard Time
The following table gives the date and time of the Moon's phases for the year. The times listed are for Pacific Standard Time (Coordinated Universal Time − 8 hours) . This time zone may have different names in different countries. If Daylight Saving Time is in effect, add one hour to the times listed.

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.

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 |
