moon phases

Waxing and waning

Moon phases are the cycle of appearances the moon presents as it orbits Earth, from new moon through waxing crescent, first quarter, waxing gibbous, full moon, then waning gibbous, third quarter, and waning crescent before returning to new.

The complete cycle takes about 29.5 days.

The app tracks moon phases for planning night photography.
