CS2 Premier mode has run through four full seasons since launch, and the pattern is now clear: after one unusually long inaugural season, Valve settled into a consistent ~six-month cadence tied to the CS Major calendar. Here’s every season in one place.

How long are CS2 Premier seasons?
Why Season 1 lasted 488 days
CS2 launched in September 2023 without a published season schedule. Valve treated the first season as the game’s competitive bedding-in period — they were still tuning the rating algorithm, adjusting the map pool, and monitoring player distribution. The result was a season that ran for over a year before Valve felt comfortable resetting ratings and committing to a regular cadence.
The six-month pattern (Season 2 onwards)
Starting with Season 2, the pattern snapped into focus:
- Season 2: 167 days (Jan 28 – Jul 14, 2025)
- Season 3: 188 days (Jul 15, 2025 – Jan 19, 2026)
- Season 4: ~180 days (Jan 21 – Jul 20, 2026)
That’s consistently five to six months per season. The slight variation comes from the Majors calendar — seasons don’t end on a fixed calendar date but rather shortly after the conclusion of each CS Major.
Why seasons end after CS Majors
CS2 Majors are the biggest events in the competitive calendar. Valve times the Premier season reset to land just after a Major concludes, which serves two purposes: the leaderboard standings going into the season-end push reflect peak competitive activity, and the new season’s fresh map pool aligns with whatever map changes Valve makes for the post-Major era. Season 2 ended shortly after the Austin Major; Season 3 ended after the Bucharest Major; Season 4 ends after IEM Cologne 2026.
CS2 Premier Season 4: current season
Season 4 began on January 21, 2026 and ends on July 20, 2026 — confirmed by Valve. The map pool change for Season 4 brought Anubis back in, replacing Train.
With about two months left in the season, now is the window where ratings matter most — the leaderboard positions you hold in late June are effectively your final standing. Check the CS2 Season 4 countdown timer to see exactly how much time is left and plan your ranked sessions accordingly.
When does CS2 Season 5 start?
Valve has not announced a start date for Season 5. Based on the existing pattern, Season 5 should begin within a day or two of Season 4 ending — Valve has not run an off-season between Premier seasons since Season 1. If the cadence holds, expect Season 5 to launch around late July 2026 and run through early January 2027, likely ending after the next CS Major.
There is no confirmed name, map pool change, or rating reset amount for Season 5 yet.
FAQ
Does CS2 Premier have an off-season? No. Valve resets the rating within days of the previous season ending and immediately opens the new season. There is no gap period where Premier is unavailable.
How many days until the next CS2 season? Season 4 ends July 20, 2026. The live CS2 countdown shows the exact time remaining down to the second.
What changes at the start of each new CS2 season? Every season brings a CS Rating reset (all players start fresh), a map pool update (one map rotated in, one out), and usually minor rating system tweaks announced in a Valve blog post. Season 4 added Anubis and removed Train.
How long is a CS2 Premier season? Since Season 2, each season has lasted between 167 and 188 days — roughly five to six months. Season 1 was an outlier at 488 days.
Why was CS2 Season 1 so long? Valve used Season 1 as an extended calibration period while the game and its rating system were still maturing. No schedule was ever published for it. From Season 2 onwards, Valve shifted to a predictable semi-annual reset.
