they really dont have a set shed time, they shed because they get bigger. mine can shed twice in a month. and sometimes he can go a couple months without shedding.
i just got my lil guy a week ago and he has already shed my wife said it was pretty cool to see cuz with our 7 ball pythons they shed and it takes them forever to shed and she said that one minute he was really dark and was afraid he might be stressed out so she walked away came back and he was white and then couple minutes later he was all done shedding lol crazy stuff snakes take forever to shed
