- Sources
- Official publisher season announcements and battle-pass pages are preferred. Reporting and community reference archives support some older launches and are labelled in period details; they do not silently confirm reward expiry. Every period links to its sources and checked times. Popular games first is an editorial order informed by recent public Steam charts and the latest retained Xbox US chart, joined by exact product IDs. It is not a worldwide player-count ranking; platform ranks are not combined and missing coverage is unknown.
- Dates
- The shared axis uses a UK calendar. Explicit timestamps retain their source time zone in details. Date-only records never imply an exact expiry hour; where the source omits a zone, remaining calendar days use UK dates. End not confirmed means the bounded review did not verify an end date.
- Meaning
- Season, pass, purchase, earning and claiming dates are distinct. An announced next start does not prove the previous pass expires. Purchased persistent passes remain separate from temporary purchase windows. Shading represents elapsed calendar time, not player progress.
- History
- Named pass records can extend back to each game's earliest reviewed source; there is no rolling two-year cutoff. Coverage still varies by game and remains incomplete where named periods or dates have not been reconciled. The 30, 90, 180 and 365-day views show only the selected window. Reported season ends are distinguished from purchase, earning and claiming cutoffs; a next-launch handover is not a verified expiry. Call of Duty product eras and Overwatch's legacy and 2026 numbering remain separate. League event passes, Wild Passes, HoYoverse pass periods and Dota Compendiums are included only as progression records, not ranked seasons. Paid tiers are not duplicate passes. Server-local times are preserved without inventing a universal UTC hour. Conflicting and undated records remain gaps.
- Estimates
- Dashed estimates can cover current or announced upcoming periods with a known start. They use the median of at least two comparable completed intervals, preferably three to five, or an explicitly labelled expected handover at an announced next start. Details show sample size, observed range, method and sources. Changed pass formats are not blindly extrapolated. Estimates never confirm reward deadlines or expire owned persistent passes; official ends take precedence. Passed estimates remain passed, and unannounced seasons are not projected.
- Coverage
- Direct publisher dates and retention rules are source-backed facts; archive-only dates are reported history, and missing deadlines remain gaps. The checked snapshot is retained until the next source review; countdowns use your device clock. Existing exact-ID portrait covers are used where available; other official artwork is contained without cropping. Followed games are saved only in this browser, and shared URLs preserve games, range, historical position and selected period.
