I hate it. I am one of those crazies who doesn't like all the breaks. If I was able to stay at home with my kids, it might be different, but I can't. My youngest comes to work with me (which is a blessing) but we don't really get to enjoy that time.
Another complaint I have (which thankfully will soon no longer be a problem) is that this calendar is really hard when you have a blended family and share custody.
Just for example...we split the 2 weeks of Christmas break. Every other year we swap...one parent has the week before, and the other has the week after. We've never had good terms with my husband's ex, so we literally have to go by the papers to avoid conflict. When the break doesn't begin until the 20th, one parent will have a hard time making all the plans with respective family events, vacation, etc.
Certainly, you can't please everyone and I would never expect an entire school system to revolve around what I want/need, but with the changes, it makes it hard!
