Is the moon in the same position every Mid-Autumn Festival?

Because the moon's orbit around the earth is not circular, but nearly elliptical, the distance the moon travels in orbit every day is not consistent.

The fifteenth day of the lunar calendar is usually a full moon, and the first day of the lunar calendar is the first day when the moon cannot be seen on the earth, and then it is counted. In this way, the new moon must be the first day, but the full moon may not be on the fifteenth day of the first lunar month, but between the fourteenth and seventeenth lunar months.

According to rough statistics, the full moon appears in the lunar calendar1May, 40% in the lunar calendar1June, 10% in the lunar calendar1April,1July.

As we all know, the same object looks bigger when it is near us and smaller when it is far away from us. So is the moon. Because its orbit around the earth is approximately elliptical, from the perspective of the earth, the moon is the largest at perigee and the smallest at apogee.

At the full moon, if the moon moves near perigee, it will look bigger than the full moons in other months. At this time, the full moon is called the "maximum full moon".
