Academic Calendar

The academic year consists of two regular terms (fall and spring), a winter term and one summer term. Lehigh University defines a regular semester as 14 weeks and 70 individual days of instruction. When classes have ended, two (2) full days are scheduled as the reading-consultation and study period, to allow students time to prepare for final examinations. Final examinations are scheduled on nine (9) consecutive calendar days, and each day will have four (4) consecutive 3-hour exam periods per day.  The winter term is four (4) weeks and the summer term is twelve (12) weeks with measured sessions.

Please note the academic calendar is subject to change without notice. The most current calendar is available on the Office of the Registrar website.
