UCI Academic Calendar

The University of California, Irvine (UCI), located in Irvine, California, operates on a quarter system, which divides the academic year into three main terms: Fall, Winter, and Spring, with an optional Summer Session. This structure allows for a more intensive and focused curriculum, with each quarter typically lasting about 10 weeks. The academic year generally begins in late September for the Fall Quarter and concludes in mid-June with the Spring Quarter. UCI’s calendar includes standard breaks such as a winter recess in late December and a spring break in March, aligning with many other institutions in the region. This system offers students flexibility in course selection and opportunities for accelerated learning or internships during the summer.

• Fall Quarter Start: September 25, 2025 (estimated, based on typical late September start). Instruction begins, marking the official start of the academic year.

UCI’s quarter system aligns with other University of California campuses, offering a distinct rhythm compared to semester-based institutions. The shorter terms can be advantageous for international students, allowing quicker progression through coursework, though they may require adjustment to the fast-paced schedule. Breaks often coincide with national holidays like Thanksgiving and winter festivities, providing predictable downtime. Additionally, UCI’s Summer Session offers flexibility for students aiming to catch up on credits or explore specialized programs. While exact dates for the 2025–2026 academic year and admissions cycle are subject to confirmation, the estimated timelines reflect historical patterns and regional norms for public universities in California.
