They have to start earlier or else they’d be in school until June when it’s blazing hot & dry. In August, the weather is a tiny bit cooler. I agree though, it took a while for me to get used to it having grown up with school usually starting around Labor Day.
I’m not sure what AZ state you live in, but it’s definitely not cooler in August here. These kids get 3-2 week vacations throughout the year, fall, Xmas, and spring. When I was in school, we were done 2nd week of June, and back in just after Labor Day.
You’re really beginning to worry me, now with ALL the kids in school, you’re gonna have wayyyyy to much free time on your hands. I suspect there will be a few Fig Newton runs during the day!!
