Snake reproduction. ?

So how long is the window open for snakes to reproduce? Do they have a couple of weeks, months or can they other reproduce? Help is appreciated, can't find this anywhere on the internet. :)
Answers:    Most snakes mate in the spring after hibernation. I can actually get mine to lay 2 clutches sometimes. They will lay one within the spring and then late summer or fall.
Why give up your job the window open?
Fresh air doesn't influence them
