The updated calendar says this:
Dec 23-Jan 1 Winter Recess (Schools closed)-Dates updated
We can take a little bit of credit for the change as pressure from parents and rank and file teachers, which we certainly helped to motivate, convinced the UFT to keep fighting for December 23. Our April 26 blog piece and our NY 1 appearance did something to bring this issue to the public sphere where we looked reasonable by using precedent. When December 23rd came on a Monday in the past, it was always a day off going back 33 years. It will be this year too. We didn't ask to give back a day like others did either. The rest of the calendar is unchanged.
Enjoy your full Winter Recess everyone!
