The CMU Academic Calendar 2025‑2026 schedule contains every key date you need from application and enrollment deadlines, tuition payment due dates, and course add/drop periods to university holidays and final exam schedules.

The Carnegie Mellon academic calendar allows students to stay ahead of CMU registration deadlines, plan their semester around the CMU exam schedule, track CMU term dates, and never miss the last day to withdraw without penalty.

• Fall Semester (late August to mid‑December; approximately 14 weeks of instruction + 1 week of finals)
• Spring Semester (late January to early May; 14 instructional weeks + 1 week of finals)

In addition to these, CMU offers a Summer Session split into Session I, Full Summer, and Session II—each providing accelerated course options for makeup work or early degree completion.
