School daze

New Schools Chancellor Richard Carranza has spent much of his nine weeks on the job touring classrooms in the city’s 1,800 schools. He won’t on Thursday; kids are home. It’s Anniversary Day, which means nothing to no one. It used to be called Brooklyn-Queens Day, which meant nothing to no one.

Yet thanks to the idiotic calendar the city negotiated with the teachers union, the vast system will nonetheless be shuttered, leaving parents scrambling for childcare. Teachers work, though on what pressing tasks, this late in the year, we can’t imagine.

Then it’s back to class for everyone on Friday, before a three-day weekend — since Monday is June Clerical Day, another day off for kids that means nothing to no one.

Dumb gets dumber. The last two days of the year are June 25 and June 26, a Monday and Tuesday. That final day is a half day.

While the citywide attendance hovers around 90%, it will fall through the floor by expecting kids to trudge back to class after a weekend with barely a week before the Fourth of July. That’s exactly what happened last year.

It’s a school system: learn something. Cancel the nonsense holidays and end on a Friday.
