What follows is a simple explanation of the phases of the moon and how to know them by sight:
The Waxing Crescent Moon
rises after sunrise and sets after sunset --
it is only seen in the night sky for a short
time after the sun goes down.
The dark side is to your left, more or less,
and the bright Crescent is to your right
The Waxing First Quarter Moon
rises about at noon
and sets about at midnight.
It is dark on the left and bright on the right
The Waxing Gibbous Moon
rises in the middle of the afternoon
and sets before well before sunrise.
It is perfectly round on the right side,
but bulged out past half-way on the left.
The Full Moon
rises almost exactly at sunset
and sets almost exactly at the next sunrise.
When completely full, it is a perfect circular disk.
The Waning Gibbous Moon
rises in the early evening
and sets some time after sunrise.
It looks perfectly round on the left side,
but bulged out past half-way on the right.
The Waning Last Quarter Moon,
also called the Third Quarter Moon,
rises about at midnight
and sets about at noon.
It is dark on the right and bright on the left.
The Waning Crescent Moon
rises between midnight and dawn,
but fades out when the Sun comes up.
The dark side is to your right, more or less,
and the bright Crescent is to your left.
The New Moon is the Dark Moon,
you will see no Moon at all.
It rises at sunrise
and sets at sunset.
