When exactly IS Spring Break?

[HopperFan]

Spring Break has always been a 4-6 week window depending on where Easter lands on the calendar.

This. Spring break for colleges and high schools in Georgia are from first week of March through week before Easter. They want the colleges spread out and the school districts, particularly in Atlanta area are over the course of a few weeks, then many privates are either early with long Easter weekend or they hit the week before Easter. WDW is pretty busy the entire time. We were there last week, supposedly a slower spring break week, and it was busy but Sunday - the crowds swelled.
