- The "spring begins on March 20th" definition is based on the date of the vernal equinox, an ASTRONOMICAL definition based on the earth's position in relation to the sun.
- The "spring begins on March 1st" definition is based on a METEOROLOGICAL definition, which is based on temperatures.
There are even more interpretations out there, but these are the two most common. Bottom line is that there has been no official decree or law setting the date, so you get to decide.
For me, with all the changes going on in nature already, especially with the birds, I say "it's already spring!"
Now watch another snowstorm happen.....Sources: Old Farmers Almanac, Accuweather.com
