As a student in the Chicago Public Schools, I grew up with holiday vacations labeled, “Clean up week” or “Winter break.”
“Winter break” always fell around Christmas. “Clean up week” was in April; sometimes it hit around Easter.
But this fall, an increasing number of school calendars will remove all references to religious holidays for 2015-2016.
Students will still be off for the same days as in previous years, but the religious holidays of “Easter, Christmas, Passover, etc.” will not be named. In many districts, those dates will simply be noted as “No school for students or staff.”
