The eight lunar phases describe how the Moon's appearance changes over roughly 29.5 days as it orbits Earth. The cycle begins with the New Moon, moves through Waxing Crescent, First Quarter, and Waxing Gibbous, reaches Full Moon, then continues through Waning Gibbous, Last Quarter, and Waning Crescent before returning to New Moon. These phases result from the shifting angles of sunlight reflecting off the Moon as seen from Earth. Below you will find each phase in order, key identifiers, and practical tips for observation and naming.
