Full Moon

A Full Moon is the phase of the Moon when it is fully illuminated as a circle. Full Moons occur approximately every 28 days. Lunar eclipses may only occur during a Full Moon, while solar eclipses may occur only during a new moon.

Two full moons in a month - a fairly rare occurrence (every 32 months) - is called a "blue moon," leading to the phrase "once in a blue moon" to describe things that happen rarely.

The phases of the moon are:

• New Moon
• Waxing Crescent (looks quarter full)
• First Quarter (looks half full)
• Waxing Gibbous (looks three quarter full)
• Full
• Waning Gibbous (looks three quarters full)
• Third Quarter (looks half full)

• New Moon(again)
