Moon Phases

The Moon Phases schedules gives to the dates of the new, first quarter, full, and last quarter moons each month of the year.

A new moon is the first lunar phase that happens about once a month or, 29.53 days on average. The moon itself is not visible though you may be able to “see” it because it blocks the visibility of the stars behind it.

A full moon occurs when the Earth is directly between the Sun and Moon so that the moon looks completely illuminated when you look at it. It happens about once a month or, 29.53 days on average.

The first quarter moon occurs between the new moon and full moon. The last quarter moon occurs after the full moon and before the next new moon.
