This is an urban legend.
There is no special change in gravitation on December 21 (the winter solstice in the Northern Hemisphere, when the Earth is closest to the Sun). If an egg cannot be balanced at any other time, it will not be any more possible on December 21.
And, oddly enough, the original date suggested was the vernal equinox (March 21 in the Northern Hemisphere). Nothing special about balancing then either.
Noon typically ends at 12:00 p.m. (midday) and the afternoon begins.
An egg can stand up on its end at any time of the year with a bit of balance and patience. There is no special connection between the egg standing up and the spring equinox. It is a fun experiment that can be done with practice and the right egg.
The end correction of a meter bridge can be measured by comparing the balance point of a known standard wire to the balance point of an unknown wire on the meter bridge. The difference in lengths between the two balance points is equal to the end correction.
It is possible, but you must have very steady and strong fingers.
In a denser liquid.A raw egg will sink in fresh water, but float in salt water. It also depends on how fresh the egg is.Set an egg in cold water-If the egg stay at the bottom - it is fresh.If the egg is at an angle on the bottom - it is still fresh and good to eat.If the egg stands on its pointed end at the bottom - it is still safe to eat but best used for baking or boiled eggs.If the egg floats - it is best discarded.
i think it ends on December 3 at noon
With practice you can balance an egg on its end on any day of the year.It is an urban legend that you can only do so on the first day of spring and autumn because of the earth's tilt on those days.

High Noon Toons ended in 1995.
afternoon
Noon typically ends at 12:00 p.m. (midday) and the afternoon begins.
i did my science fair project on this!! the time of year does not affect whether they stand on end. it is the texture of the bumps on the eggshell. some eggs can stand on end, but some never will! the whole "equinox" thing is only an urban legend.
January 20 at Noon.
An egg can stand upright due to its shape, which is slightly asymmetrical. The wider end of the egg is more stable when placed on a flat surface, allowing it to balance. Additionally, the egg's contents, including the yolk and albumen, shift slightly when the egg is moved, helping to find the center of gravity that supports an upright position. The combination of shape and internal dynamics permits an egg to stand, albeit not very securely.
You can definitely have a noon wedding! Just be sure to indicate on your invitation what the meal will be - typically lunch since the ceremony will end after noon. If it is a Sunday wedding, you could also serve a large brunch.
