Wake County is a fiasco... Different schools within the district are on different schedules. You have traditional Aug/Sept-June, and then you have year-round, which basically you go to school for 9 weeks, then get three weeks off. You have four cohorts of kids all staggered.. So, think of it as group A goes weeks 1-9, and are off for weeks 10-12, repeat. Group B is off for week 1-3, but go for 4-12, repeat. Group C is in school weeks 1-3, are off for 4-6, then go for six more weeks, repeat, and group D goes for weeks 1-6, off for 7-9, go for three weeks, repeat. My understanding is they use it in schools that are overcrowded, so at any given time 25% of the students enrolled at the school are on break, thus increasing capacity by 33% of the original capacity. Oh yeah, my understanding is there is no guarantee that multiple children from the same family will be on the same schedule either. And I have no idea what parents do with their kids for three random weeks , three times per year that aren't part of the traditional school calendar breaks.
