Yep, I Googled it. Oh, I know what the Vernal Equinox is, but I like to see what comes up when I hit the search button.
I found this website: http://earthsky.org/astronomy-essentials/everything-you-need-to-know-vernal-or-spring-equinox
Maybe it will work for you one day . . . maybe it won't . . . things come and go. But here's an excerpt:
What is an equinox? Each equinox and solstice is an astronomical event, caused by Earth’s tilt on its axis and ceaseless motion in orbit. The equinox is also an event you can think about as happening on the imaginary dome of our sky.
The Earth-centered view is that the celestial equator
is a great circle dividing Earth’s sky into Northern and Southern
Hemispheres. The celestial equator wraps the sky directly above Earth’s
equator. At the equinox, the sun crosses the celestial equator, to enter
the sky’s Northern Hemisphere.
The Earth-in-space view is that,
because Earth doesn’t orbit upright, but is instead tilted on its axis
by 23-and-a-half degrees, Earth’s Northern and Southern hemispheres
trade places in receiving the sun’s light and warmth most directly, as
Earth orbits the sun. We have an equinox twice a year – spring and fall –
when the tilt of the Earth’s axis and Earth’s orbit around the sun
combine in such a way that the axis is inclined neither away from nor
toward the sun.
At the equinox, Earth’s two hemispheres are
receiving the sun’s rays equally. Night and day are approximately
equal in length. The word equinox comes from the Latin aequus (equal) and nox (night).
But, since Earth never stops moving around the sun, these days of equal sunlight and night will change quickly.
I like when the sun crosses over into the Northern Hemisphere . . . it means MORE sunlight! My whole outlook changes when there's more sunlight!!
