Adjustments to the University of Nebraska–Lincoln’s academic calendars for 2023-24 and 2024-25 were accepted by the Board of Regents on Sept. 30, 2022.

They include 15-week fall and spring semesters with a spring pre-session preceding the regular spring semester. These pre-sessions ("J-terms" or January terms) are part of academic calendar explorations at the recommendation of Ted Carter, NU system president.

Fall and spring semesters are synchronized with the University of Nebraska at Omaha and University of Nebraska at Kearney calendars. However, summer sessions differ on the undergraduate campuses. Key dates for 2023-24 and 2024-25, including NU summer session dates, are listed on the Office of the Registrar's website.

The academic year calendar adjustments have extended both calendars by two weeks. In 2023-2024, faculty with academic year contracts will not be required to return from the holiday closedown until Jan. 15 (effectively Jan. 16 due to Martin Luther King, Jr. Day). They will be expected to continue their work through May 24. For 2024-2025, faculty with academic year contracts will not be required to return until Jan. 13 and will be expected to continue their work through May 23. A complete list of contract dates and working days is available on the Office of the Executive Vice Chancellor's website.

The Office of the Executive Vice Chancellor will issue a call to fund spring pre-session courses for 2024 and 2025.
