Waxing Crescent – The Moon appears to be partly but less than one-half illuminated by direct sunlight. The fraction of the Moon’s disk that is illuminated is increasing.
First Quarter – One-half of the Moon appears to be illuminated by direct sunlight. The fraction of the Moon’s disk that is illuminated is increasing.
Waxing Gibbous – The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon’s disk that is illuminated is increasing.
Full Moon – The Moon’s illuminated side is facing the Earth. The Moon appears to be completely illuminated by direct sunlight.
Waning Gibbous – The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon’s disk that is illuminated is decreasing.
Last Quarter – One-half of the Moon appears to be illuminated by direct sunlight. The fraction of the Moon’s disk that is illuminated is decreasing.
Waning Crescent – The Moon appears to be partly but less than one-half illuminated by direct sunlight. The fraction of the Moon’s disk that is illuminated is decreasing.Following the waning crescent is the new moon as the cycle begins again.
