It's the first day of Spring!

Today is the first day of spring.  This is the Vernal Equinox: this day was named after a man named Vern. 
KIDDING! 
Vernalis is Latin for spring. 
Equinox means "equal night"
Why?
This date is chosen for astronomical reasons. 
The Earth spins, and it is tilted, and it orbits the sun., and this date is the time of year when the sun crosses the plane of the earth's equator, making night and day of approximately equal length all over the earth.

March is also where we see flowers start to come back and bloom. HAPPY SPRING!
