Anyone who's tried to plan family vacations around the school calendar knows it's a total gouge fest, prices double on flights & hotels when they know NYC school kids are off. So I'd like to get ahead of the curve for 2019.

Does anyone know how the dept. decides which week in February and April will be "the one"? April is always the week before OR after Easter - how do they pick? What about February? Is it always the week that includes President's day?

This year for 2018, why did they decide to include the Friday (2/16)
