Labor Day (Sep 7) gives a breather. Fall break hits Nov 23-25, followed by Thanksgiving. Finals wrap December 7-11, with commencement December 11-12. Class work ends December 4. Don’t sleep on that pre-finals week for last-minute prep.
Think about the student who partied too hard during welcome week and scrambled to drop a killer class before the restrictive deadline. Learn from that mistake.

Spring 2027 starts January 11. Martin Luther King Jr. Day (Jan 18) is a holiday. Add/drop moves quick—100% refund by Jan 19. Spring break March 15-19 feels like a lifesaver mid-semester. Withdrawal deadline April 9. Classes end April 30, finals May 3-7, and commencement May 7-8. Winter intersession (Dec 14-Jan 8) offers a head start for eager beavers.
Summer Semester Calendar
