It really is all over the place. There's quite a bit of variation, even within the same region.
My college break is first week of March.
My kids have a long weekend over Easter and another in mid-April.
My friend who goes to a college about 20 miles from me has her spring break a week later than mine.
Her DD has the full week after Easter off.
And her sister's kids, just 5 miles down the road, have a long weekend at Easter and then the first full week of April off.
It all makes it pretty tough to plan anything for our families together over breaks! LOL
