If the three-month recess, currently held from mid-June to mid-September was moved to a period from mid-November to mid-February, schools would save significantly on heating costs and would have lower chances of weather-related cancelations, while students would have the option of enjoying what niter, as many do, or avoiding the requirement to venture outside during the winter months.
Alternately, the week could be reduced to six days (eliminating Tuesday) and a thirteenth month, Tuesmonth, added between January and February. In this case, Winter Vacation would run from the beginning of December to the beginning of February
