Today ends Daylight Savings in the US. How are you gonna explain it to your kids in the future?

I’m not sure how I’ll explain it to my kids, but I do remember how Daylight Savings worked when I was a kid. Basically, the government would change the clocks so that we would have an extra hour of daylight in the summer. In the winter, they would change the clocks back so that we would have an extra hour of darkness. I’m not sure how they decided when to change the clocks, but it always seemed like a pain.
