When did you see the biggest moon? When did you see the biggest moon?

1. When did you see the biggest moon? The moon you saw on 16 is the largest.

2. There is a folk saying "15 moons 16 circles" because the moon revolves around the earth in an elliptical orbit, and it takes an average of 29 days 12 hours and 44 minutes from one full moon to the next. When you look at it, the moon, the earth and the sun are closest to a straight line, so the moon is the roundest and brightest.

3. However, due to the speed of the moon's rotation, the time to reach Wangwang is different every time, mostly in the early morning of the 16th or 17th day of the lunar calendar every year.
