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.

Peak and shoulder ratings are rough guidance, not a schedule. Weather, elevation and the year can shift any species by weeks.

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