The school is allowed to make an exemption for a maximum of 10 days, above that you need to contact the school attendance officer. This can only be provided if the reason falls under some specific types.
If you want to take your children on a holiday outside the national holidays, you have to provide proof that this only a possibility during term time.

So now you are not free to do whatever you wish or force schools to teach the way you would like to.
And this is great.
And I also pulled my kids from school once or twice to get a better price on skiing but I am ashamed of myself.
Law is not optional.
Sounds like a real day off, though. ;)
Like, can the tool be expanded to do:
1) Finding vacation time for a group of people (family? college friends?)
2) Can you include black-out days (school days for kids, whatever your specific job requires, etc)
I mean, as long as _I'm_ not responsible for making this thing I can make feature suggestions all day :)
