If you mean after the blue phase around 5 days, give or take. If you mean since the last shed, it would depend on the snake. And even then it would not be easy to predict. I've had some sheds that were really close together (a few weeks) and others that were really far apart (to the point I was thinking where the heck is it?). I couldn't say if others have had the same experience though.
Hope this helps!
