There are two rather significant "breaks" coming up.

Thanksgiving

25-Nov.-2021 to 26-Nov.-2021

4th Thursday in November (Thanksgiving & Day after)

Winter Break

Varies by School

Schools typically schedule a 1- to 2-week break during the final weeks of December and the first weeks of January.

The break typically begins the week before Christmas (Dec. 25) and ends shortly after New Years Day (Jan. 1)
