Pat, once they are used to being handled you can get them out whenever you like except if they are digesting or in shed. If you want to visit with George, by all means just get him out. At a year, unless he seems to be stressing for some reason, you can easily have him out for an hour with no ill effect.
P.S. Supervised of course. Never leave you eyes off of a corn snake unless it is secure in its enclosure or other snake proof container.
