Fall Semester Calendar
Fall 2026 hits the ground running on Monday, August 17. That’s when class work officially begins for the main 16-week stretch. Registration deadlines sneak up fast – get in early to snag those prime spots.
Don’t sleep on Labor Day (September 7) – it’s a university holiday. Fall break lands November 23-25, perfect for recharging before finals push. Exams run December 7-11, with commencement wrapping things up December 11-12. By December 16, grades are in. It’s a solid four months packed with learning and those classic OSU football weekends.
Pro tip: That pre-session from August 3-14 gives ambitious folks a head start.
Spring Semester Calendar
Spring 2027 fires up January 11. Classes begin right after the winter break hustle. Martin Luther King Jr. Day on January 18 means a nice early breather.
Spring break (March 15-19) comes at the perfect time to shake off winter blues. Watch for the W withdrawal deadline on April 9. Finals hit May 3-7, commencement May 7-8. The semester closes out strong, setting you up nicely for summer plans or that next big step.
Summer Semester Calendar
Summer 2027 offers breathing room with the main 8-week term starting June 7. You’ve got shorter 4-week blocks too – first from June 7-July 2, second July 6-30. Perfect for catching up on credits or exploring new topics without the full load.
Enrollment dates vary by session, so check specifics. Deadlines for adds, drops, and withdrawals adjust to the shorter formats. It’s flexible – whether you want one intensive class or a couple back-to-back.
Registration Deadlines
Early registration rewards the prepared. Priority goes to certain groups like honors students or athletes – smart move if you qualify. Late registration? It happens, but that late fee stings after the cutoff.
Schedule changes through add/drop keep things fluid at the start. Waitlists can be your friend if a section fills up quick. Stay on top of these to avoid that frantic last-minute scramble. Think of your roommate who waited until the final hour and ended up with a brutal Tuesday-Thursday schedule. Don’t be that person.
