# How Many Days Are In A Lunar Cycle?

**A lunar cycle is 29.5 days long.**

A lunar cycle, also known as a moon cycle, is the length of time it takes for the Moon to complete one full orbit around Earth. This is the time it takes for the Moon to go from new moon, to first quarter, to full moon, and finally back to new moon again. A lunar cycle is 29.5 days long.

## How Many Days Does It Take For The Moon To Complete One Orbit Around Earth?

**One orbit of the moon around Earth takes 27.3 days.**

It takes the moon 27.3 days to orbit around Earth. This is the same amount of time it takes for the moon to rotate on its axis. This is why we always see the same side of the moon!

A lunar orbit is when the moon goes around Earth. The time it takes for the moon to go around Earth once is called a sidereal month. It takes the moon 27.3 days, on average, to orbit Earth. This is also the amount of time it takes for the moon to rotate on its axis. That’s why we always see the same side of the moon!

Here’s a fun fact: the moon is actually moving away from Earth at a rate of 3.8 centimeters per year!

## How Long Is One Sidereal Month?

**A sidereal month is the length of time it takes the moon to orbit the earth and return to its original position relative to the stars.**

A sidereal month is the time it takes for the Moon to complete one orbit of Earth with respect to the stars. It equals 27.321661 days (27 d 7 h 43 min 11.5 s).

This may be contrasted with the synodic month, which is the period of the Moon’s phases as seen from Earth. The Moon completes one orbit of Earth with respect to the Sun, resulting in the New Moon, first quarter, full moon, and last quarter phases being observed from Earth. The synodic month equals 29.530589 days (29 d 12 h 44 min 2.9 s).
