When is the moon at its fullest?
The moon is not round at the same time every year, but the time difference between the circles is very small, so we approximately think that the moon is round on August 16th of the lunar calendar, the day after the Mid-Autumn Festival. Generally speaking, the Mid-Autumn Festival is round, but as the saying goes, "the moon on the 15th is round".
Special case of the moon circle:
Many mainstream astronomers don't agree with the terms "super moon" and "super super moon" because scientifically speaking, it is more accurate to call it a perigee full moon.
When the full moon rises from the horizon, it seems that the moon we see is bigger and brighter than when it rises to the zenith. At this time, the perigee month is about 14% brighter than the apogee month (depending on meteorological conditions). But this change in size and brightness is actually not easy for the naked eye to detect.
