The IUB academic calendar 2026-2027 is the official administrative schedule for undergraduate students, graduate researchers, faculty, and university staff at Indiana University Bloomington.

Governed by the Office of the Registrar, this master directory outlines every critical date across the entire academic year—including course registration access windows, fee payment deadlines, official campus holidays, midterm evaluations, final exam periods, and commencement ceremonies.

Operating on a traditional semester-based structure, the IU Bloomington academic calendar 26-27 splits the academic year into two standard 15-week terms—Fall and Spring—alongside accelerated summer sessions and intensive 3-week winter/intersession blocks.

Under the overall IU academic calendar 26-27, each regular semester comprises 15 full weeks of active instruction followed by one designated week for final examinations.

To maintain full-time undergraduate status for financial aid, campus housing, and scholarship eligibility, students must register for at least 12 credit hours per term.

However, an average load of 15 credit hours per semester (30 units per academic year) is recommended to complete a standard 120-credit bachelor’s degree within four years. Graduate students are typically classified as full-time at 8 credit hours per semester.
