The moon's 29.5 day synodic month was the basis of lunar calendars throughout the course of history. While a lunar calendar was convenient, it presented an immediate challenge: Compared to the solar year of 365 days, a lunar year lasts an average of 354 days. Some groups decided to ignore this discrepancy.
Best Answer: The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days.The Moon spends the extra 2.2 days catching up because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth. Re-worded it a little.ne solar day = 24 hours, and 29.53 solar days is the synodic month. You are correct in saying it takes 27.3 solar days for the moon to orbit the earth-that's the sidereal month. But in addition to the moon orbiting the earth, the earth-moon system is orbiting the sun. That's why the sidereal and synodic months differ.
