Defining the Seasons

I never learned why the four seasons are dated the way they are. (If I did learn it, well, I don't remember. It's probably something like two weeks after the first day after the fourth night of something or other....)

I think it would be easier, as well as more elegant, to just define the seasons by complete months, like so:

Summer: June, July, August

Fall: September, October, November

Winter: December, January, February

Spring: March, April, May

Now I just need to convince the "powers that be" (whoever they are) to change centuries-old definitions.... How hard can it be? LOL!
