Is there a scientific basis for dividing eggs in spring?

Yes, there is a scientific basis for dividing eggs in spring.

The vernal equinox is a solar term in the solar calendar, which generally occurs around March 20, and it is the moment when day and night are equally divided. At this time, the direct point of the sun on the equator of the earth is located on the equator, and the time of day and night is equal.

On the vernal equinox, the egg can stand upright because of the gravity and centrifugal force produced by the earth's rotation, because the gravity and centrifugal force of the earth are balanced with each other at this time.

This phenomenon will also occur in other solar terms, but the phenomenon of vernal equinox and autumnal equinox is the most obvious, because the direct point of the sun is located on the equator, and the centrifugal force is the smallest in these two solar terms.

Therefore, it is a scientific phenomenon to divide eggs in spring, but not all eggs can stand up, because the shape and center of gravity of eggs will also affect the stability of standing up.
