How do I know what Fruits and Veggies are in season?

Hello!

How do I know what Fruits and Veggies are in season?

I know some obvious stuff like apples and squash in fall, and watermelon in summer. But there are lots of produce that I'm not sure.... People say look at the prices, but I haven't been shopping for myself much - and when I wanted strawberries in the dead of winter - I'd buy them. Now I want to be a financially sound consumer...

P.S. I live in the Northern Hemisphere - PA - USA....
