Have you ever asked your principal why your school starts on the day it does? Everyone starts on a different day. Why? What's the reason? No one seems to know. Do they just randomly choose a date ?

I think it would be great if all schools in Montana started and ended the same days, then let local school boards make their own schedules fit between those dates.

Stores, recreational facilities, traffic signs, day care centers, etc. would all have a single date with which to work. Just pick a date, like the first Tuesday after Labor day to start and the Friday before Memorial Day to end. What you do between is your choice. At least everyone then is on the same page.
