Rainbow Six Siege Year 11 Season 2: Operation System Override ends on September 1, 2026 (verified June 26, 2026). Track the live countdown for Rainbow Six Siege Year 11 Season 2: Operation System Override. Synced with official developer announcements and updated every second in your browser.
How Long Does a Rainbow Six Siege Season Last?
Ubisoft has run Rainbow Six Siege on a strict 91-day seasonal cadence for years — every season from Year 9 Season 1 through Year 11 Season 1 has lasted exactly 91 days end-to-end. With Year 11 Season 2: Operation System Override launching on June 2, 2026, the expected end falls around September 1, 2026 when Year 11 Season 3 is scheduled to debut.
That ~91-day window is the planning horizon for any seasonal goal: completing the Battle Pass before rewards expire, climbing toward the Champion rank cutoff under Ranked 3.0, or finishing event challenges before the rotation closes. Operators rotate in at season launch — Dokkaebi received the Remaster at the start of Y11S2 — and balance patches typically ship mid-season.
Why Every R6 Season Is 91 Days
Ubisoft locks each Year into four equal 91-day quarterly seasons — Year 11 follows the same Y9 and Y10 cadence, with launches in March, June, September, and December. The schedule was tightened after the variable-length seasons of earlier years, and Ubisoft has not deviated since. That predictability lets players plan Battle Pass progression, ranked grind windows, and operator unlocks without surprise extensions or shortened seasons.
Expected End for Year 11 Season 2
Based on the 91-day pattern, Year 11 Season 2: Operation System Override is expected to wrap around September 1, 2026, when Year 11 Season 3 is targeted to launch. Ubisoft has not yet officially confirmed the Y11S3 launch date, and this page updates the countdown automatically when the Y11S3 reveal trailer drops — typically about two weeks before the season transition.
