MIT Academic Calendar 2025‑2026: Important Dates & Deadlines

The MIT Academic Calendar 2025‑2026 provides every important date and deadlines from MIT application and enrollment dates, tuition payment due dates, and course add/drop windows to university holidays and final exam schedules.

Reading the Massachusetts Institute of Technology academic calendar helps you stay ahead of MIT registration deadlines, plan around the MIT exam schedule, and never miss milestones such as the last day to withdraw without a “W” or the start of the MIT Summer Session.

MIT operates on a semester system enhanced by its unique Independent Activities Period (IAP):

• Fall Semester: mid‑September to mid‑December (14 instructional weeks + 1 exam week)
• Independent Activities Period (IAP): first four weeks of January (intensive short courses, workshops, and research)
• Spring Semester: late January to early May (14 instructional weeks + 1 exam week)
• Summer Session: May through August, offering a range of accelerated and intersession courses

Whether you’re planning your 14‑week semester workload, exploring creative projects during IAP, or leveraging Summer Session for makeup credits, the MIT Academic Calendar 2025‑2026 is your guide to a successful year at MIT.
