I am in favor of a year-round school calendar, with three-week breaks in between ten-week sessions. I don't see that happening though, so don't panic, I'm not pushing for it.
Today though, as I was walking my dogs in bright sunshine and pleasant temps at 6:30AM, it occurred to me that this is a lousy time for a long vacation from school. It's easy to get up early and get the day going when the sun rises long before school starts. It's easier to wait for the bus when it's 70 degrees than 30 degrees. Summertime commuting is rarely interrupted by snow storms.
Contrast this with the dark and cold month of January... the perfect time of year to sleep in late and avoid shivering in the dark at a bus stop. The perfect time of year to head for warmer, sunnier places.
If we're going to have a 10-week vacation between academic years, let's have it in the winter time, taking off from just before Christmas until the end of February. Think of how many snow days we'll avoid.
No? Oh well. It was just a thought while I was walking my dogs.
