Moon in Third Quarter phase on August 6; next Full Moon August 28

On August 6, 2026, the Moon arrives at its Third Quarter — that ancient, reliable halfway point between fullness and darkness that human beings have marked since long before they had names for it. Half the lunar face catches the sun's light tonight, and the terminator line between brightness and shadow throws the Moon's craters and highlands into sharp, dramatic relief. This moment is one beat in a 29.5-day rhythm that governs tides, calendars, and the quiet habit of looking up — a cycle that will carry watchers forward to the next Full Moon on August 28.
