Update: Thank you to the commenter who pointed out that Thanksgiving was wrong on my calendar. Who knew it was on Thursday this year!? The files have been fixed and should be correct now.
For the last couple years our school calendar has been mostly six weeks on, then one week off. We've found this to be a good fit for our family.
I've also found it useful to have a printed calendar showing our school terms so that my kids can see at a glance when the next break is.
This year we're having to adjust our terms a little from our usual six-and-one rotation because the kids are taking some classes through Potter's School. But it's still six weeks on and one week off for the most part.
Now I say that, but if you look at the calendar below, you'll notice that we do have an extra-long second term planned. But I have a feeling during that 10-week term we'll take a few days off, except that the kids will still be doing their Potter's School classes during that time. Thankfully our planned school year is 38 weeks, so we do have some leeway for taking days off as needed.
