Schools, and my district is among the, seem to have dumped too many winter holidays in recent years, and I know in our case that is directly the result of bad weather ( Floyd, Sandy, snow, heavy flooding rains, various sleet and ice events, even a derecho in 98 here, which caused enough damage to close schools the first week IIRC ). But I remember in the 80's when I was training to be a teacher that some of my colleagues were in districts that had a week off in Feb.
