Here’s the latest overview I can provide based on UC Berkeley’s official calendars and recent campus updates.
- When classes start: Fall 2025 began August 27, 2025; Spring 2026 began January 13, 2026. These are the primary anchors for UC Berkeley’s annual schedule [UC Berkeley Academic Calendar 2025-2026].[1]
- Key deadlines you might need:
- Fall 2025: last day to add classes without a fee was September 8, 2025; last day to drop without a fee was September 1, 2025 [UC Berkeley Academic Calendar 2025-2026].[1]
- Spring 2026: spring instruction began January 20, 2026; spring-quarter start for undergraduates was January 13, 2026; deadline to drop without a fee for undergrads was January 30, 2026 [PDF calendar excerpt].[2]
- Additional resources for course listings and enrollment:
- The official Class Search site is a reliable way to locate courses, times, and instructors for current and upcoming terms: Classes.berkeley.edu.[6]
- The Office of the Registrar publishes the official academic calendar and calendar resources for current and upcoming terms: Registrar calendars page.[5]
If you want, I can pull the precise dates for the current or next term (including add/drop windows, withdrawal deadlines, and reading/review weeks) from UC Berkeley’s calendars and present a clean, term-by-term summary. I can also map those dates to your planned term and help you plan your schedule accordingly.
