Why do kids have to go to school on Veterans day but not on other important dates?

I think the real question is:

Why do they go to school on veterans day, which is remembering the sacrifices made by those in the past, and serving in the present, and they get to stay home for columbus day... which is in honor of a dude who discovered and already discovered place, and enslaved and killed untold numbers of these "savage" peoples?

I know not all places do it, but most have columbus day off...and I don't know anywhere that has veterans day off

I find if disrespectful that kids are deprived the chance to learn about veterans

It depends on the state or school district. In AZ my kids have the day off; however, I have a friends in FL and their kids go to school. I used to think every school should take the day off until I heard what they were doing in some districts. The educate the kids on the importance of our Vets and service to your country, then they host parents to an assembly and the Vets are honored at the school. Great teaching moment.
