So called "Jersey Week" is the week in early Nov that coincides with the NJ teachers convention in Atlantic City. NJ public schools are closed for the convention which is always on a Thurs and Fri in Nov and that week many NJ-ers do take their kids out of school since they'd only miss 3 days. This year the convention is Nov 10th and 11th so, to answer your question, "Jersey Week" would be the week of Nov 7th.
