The eight phases

A full cycle from new moon to new moon takes about 29.5 days. The moon grows (waxes) from new moon through crescent, first quarter and gibbous to full, then shrinks (wanes) back through gibbous, last quarter and crescent. The picture above shows the view from the Northern Hemisphere; south of the equator it's mirrored left to right.

Phases here are calculated from the average length of the lunar cycle, so dates can be off by up to a day from an astronomical almanac.
