carpet breeding?

[Apophis]

Can carpets only be bred at one time of the year? I know that other snakes can be bred multiple times. But is that stressful on the snake? I'm just curious because everyone here seems to be breeding now, but do you have to do it this early or can you wait till summer or another time?

Once per year. Doesn't have to be in the same month. Can be artificially manipulated.
