The moon's cycle, known as the lunar month, lasts about 29.5 days. When the moon is halfway through its cycle, it is at the full moon phase, which occurs approximately 14 to 15 days after the new moon. Therefore, about 14 to 15 days pass when the moon is halfway through its cycle.
The moon completes one full cycle, from new moon to new moon, in about 29.5 days. This is known as a synodic month.
Define "cycle". 29.5 days is the most common answer.
