The semester-based academic calendar provides students, faculty and staff with important dates and deadlines.

  • Semester start and end dates
  • registration
  • course add/drop/withdraw deadlines
  • reading days and final exams
  • breaks and holidays
  • future academic calendars

Every reasonable attempt is made to ensure the accuracy and completeness of this calendar. Dates can change without notice when circumstances warrant, and the calendar is updated accordingly. Individual schools may also have their own specific dates and deadlines, as it is not uncommon for the graduate and professional programs to follow different deadlines.
