What Is a Lunar Cycle
A lunar cycle is the time it takes for the Moon to complete all of its phases as seen from Earth. It begins with the New Moon and ends just before the next New Moon, as explained by NASA.
How Long Does a Lunar Cycle Last
A single lunar cycle lasts about 29.5 days, which is called a synodic month. This period is the basis for many traditional calendars and affects observable moonlight patterns.
Why the Lunar Cycle Matters
The lunar cycle influences ocean tides, cultural calendars, and agricultural timing. Understanding lunar phases helps explain predictable changes in nighttime brightness and tidal patterns.
