Spring=vernal equinox?

Question

On my calender it says Vernal Equinox. Does that mean the first day of spring?

Answer 1

Yes,

The year is broken into four major Solar Events:
1) Winter Solstice - shortest Day longest night
(Solstice means.... Sun(Sol) + stands still(stice))
(December 22)

2) Vernal Equinox - equal day equal night (Fist Day of Spring
March 21)

3) Summer Solstice - (June 21)

4) Autum Equinox - equal day equal night(First Day of Fall)
(Sep 23)

All of these events are related to the path of the Sun in the sky.
On the Summer Solstice, the Sun is very high in the sky. Such that on June 21, it tends to be very hot in the USA. This is due to the migration of the Sun all year long. Each day the Sun rises a little bit more north. This means that the Sun will rise up into the sky above my neighbor's house accross the street. The next day, the Sun will rise just a tiny little bit more north. Then it will eventually rise above the pine tree in my front yard. On that day(June 21) it will be steaming HOT in Arizona, where I live. Immediately after June 21, however, the Sun begins to rise a little tiny bit more south each day. Until Eventually it is December 22. On that Day, the Sun barely 'pops' up out of the sky for a short little visit into the sky. Then quickly sets causing North America and Europe and Asia to have night earlier then usual. The Sun continues to do this day after day, and it has been doing this North and South dance for billions of years.

Answer 2

I incredibly have consistently wanted to have fun the spring Equinox by potential of vacationing Chichén Itza. two times a year (Spring & Fall Equinox) the shadows from the nook stages of the Temple of Kukulcan run down the stairs to kind a serpent. i might desire to work out it in guy or woman!

Answer 3
