Keep Herp Calendar free
Hi, I'm Nick. I built Herp Calendar on my own and I keep it free, with no ads. If it has helped you find a herp this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.

Rare and protected species are left off on purpose. Look, don't take, and never handle a venomous snake.
