But that's the whole thing.
Why change the clocks when we could change the definition of school time, business hours, liquor/gambling licensing hours, construction noise hours, etc? Just use standard time and then base our society around the physics of the sun.
And if we do that, why can't we all just use unix time and let school can just atart whenever makes sense
The reason for daylight savings, as batshit insane as it sounds, is that it's easier to authoritatively tell people what time it is, with a one-hour jump twice a year, than to tell people to change business hours twice a year for a better experience around daylight.
It's absolutely fascinating from a psychology standpoint.
My one big hope for when countries now stop doing the stupid clock change thing, is that people become a lot more flexible around business hours and school hours, and adapt a schedule that fits people.
