Detailed explanation-1: -These eight phases are, in order, new Moon, waxing crescent, first quarter, waxing gibbous, full Moon, waning gibbous, third quarter and waning crescent. The cycle repeats once a month (every 29.5 days).
Detailed explanation-2: -The rotation of the moon around the Earth requires approximately 28 days (called the sidereal lunar month, which is 27.32 days in length). Another lunar cycle of about 14 days refers to the interval between the moon’s crossing of the equator.
Detailed explanation-3: -29 Days of the Moon New Moon to new Moon is a Moon synodic month which is 29.53059 days (29 days, 12 hours, 44 minutes, 2.8 seconds). The Moon is waxing from new Moon to full Moon and the Moon is waning from full Moon to new Moon.
Detailed explanation-4: -The Moon takes 27 days to orbit the Earth, and the lunar phase cycle lasts about 29.5 days. The lunar cycle takes a little longer because as the Moon is orbiting the Earth, the Earth is also orbiting the Sun, so the Moon needs to travel a bit further round in its orbit to complete a lunar cycle.
