MOON PHASES CHECKSKY
A lunar phase or phase of the moon is the appearance of the illuminated (lit-up)
portion of the Moon as seen by an observer, usually on Earth. The lunar phases
change cyclically as the Moon orbits the Earth, according to the changing
relative positions of the Earth, Moon, and Sun. One half of the lunar surface
is always illuminated by the Sun (except during lunar eclipses).
The progression of a given month can be estimated by the transition between one
lunar phase to the next:
New Moon (1 to 4) (4 days)
Waxing Crescent (5 to 9) (5 days)
First Quarter (10 to 13) (4 days)
Waxing Gibbous (14 to 17) (4 days)
Full Moon (18 to 22) (5 days)
Waning Gibbous (23 to 26) (4 days)
Last Quarter (27 to 30) (4 days)
Waning Crescent (31 to 35) (5 days)
To know what moon it is type: CHECKSKY.
This only works when being outdoors of course.
