Rumor has it that it's possible to balance an egg on the day of the spring equinox, but this myth simply isn't true.

However, it is true that spring is on its way.

This year the spring equinox, also known as the vernal equinox, officially started on Saturday, March 20 at 1:32 p.m. EDT.

The legend of standing a raw egg on its end on the first day of spring can be attributed to the Chinese.

They believed that due to the sun's equidistant position between the poles of the Earth at the time of the equinox, special gravitational forces apply.

While you may be able to balance an egg with patience on the day of the spring equinox, this can also be done on every other day of the year with the same results.

Winter ends and spring begins when the sun is directly overhead on the equator.

Day and night are of approximately equal length at 12 hours each on the day of the vernal equinox.

The apparent south-north migration of the sun's direct rays occurs because the tilt of the Earth's axis and the movement of the Earth around the sun.
