Our colleges go back Mid-August usually through first week in december. Go back second week of january and get out 1st week of may. Grade schools go back first week of august, get labor day, week of fall break in october, an entire week for thanksgiving now, and 2? weeks for christmas/new year. MLK day, spring break, then out the weekend or two before memorial day depending how it falls.
They changed it when I was in middle school I think. We used to go back 2 week or so. When I was a little kid we went back mid august.
