Synodic Month

Definition: A synodic month, also known as a lunar month, is the period of time it takes for the Moon to complete its cycle of phases, as observed from Earth. It is the time it takes for the Moon to return to the same position in the sky relative to the Sun.

Example sentences:

2. During a synodic month, the Moon transitions from being a thin crescent to a full moon and back to a crescent again.
