Think of the OAU academic calendar as the heartbeat of the campus. It is the master plan that tells you when to study, when to rest, and when to head home. At the university, the academic year is split into two halves: the first semester and the second semester.
The academic calendar covers all the dates of events and activities in the university for the merged 2024/2025 and 2025/2026 sessions.
To all fresh and returning students, see the academic calendar as your personal compass that keeps you from getting lost in the beautiful chaos of Great Ife. It isn’t just a list of dates; it is your roadmap to success, helping you balance the high energy lecture weeks with those much needed periods of rest and recovery.
