A new season is upon us!

The sun is shining and the flowers are blooming.

(About.com) - It's March 20th, and springtime here.

The first day of spring is also called the vernal equinox. “Vernal” and “equinox” are Latin terms meaning “spring” and “equal night” respectively. The vernal equinox occurs on March 20 or 21 each year and signals the start of spring in the Northern Hemisphere.

The idea is that on the first day of spring there are exactly 12 hours of daylight and 12 hours of darkness, but it rarely works out that way.

There is always a time each spring, and again each fall, when the hours of light and darkness are equal, but it usually occurs before the vernal equinox and after the autumnal equinox.

Here are a few other interesting facts about the first day of spring:

If you were standing on the equator during either the vernal or autumnal equinox, you would see the sun pass directly overhead, the only two times in the year when that is true.

The two equinoxes are also the only times during the year when the sun rises due east and sets due west.

In spring, the Earth’s axis is tilted toward the sun, increasing the number of daylight hours and bringing warmer weather that causes plants to bring forth new growth.

There is a persistent myth that at the vernal equinox, and only at the vernal equinox, can you stand a raw egg on its end. There is an equally persistent rebuttal that says it’s not possible at any time to balance a raw egg on its end. Neither assertion is true. With a little patience (or sometimes a lot), you can balance a raw egg on its end at any time of year. The first day of spring has nothing to do with it.
