I like that the yanks have an absolutely handicapped school scheme.
This year, I have this timetable:
March -> May: Term 1 (9 Weeks)
May: Holiday (1 Week)
May -> July: Term 2 (9 Weeks)
July: Holiday (2 Weeks)
July -> September: Term 3 (9 Weeks)
September -> October: Holiday (1 Week)
October -> November: Term 4 (9 Weeks)
There's 4 terms a year. Each is nine weeks long (Primary Schools and High Schools do 10 weeks). You start at the start of the year and you end at the end of the year. I dunno why America has its idiotic giant holidays and odd patterns. This one makes sense and is consistent.
