Answer for screen readers
The Moon takes 27.3 days to complete both its rotation on its axis and its revolution around the Earth.
More Information
The Moon is tidally locked with Earth, meaning it takes the same amount of time to rotate on its axis as it does to orbit Earth, resulting in the same side always facing our planet.
Tips
A common mistake is confusing the sidereal month (27.3 days) with the synodic month (29.5 days), which includes the Moon's phases.
