Pokémon's official August 2026 events notice confirms Ranked Battles Season M-5 and its Battle Pass from August 5 at 02:00 UTC through September 9 at 01:59 UTC. The official M-B notice was updated the same day to extend Regulation M-B through that deadline.
Editorial record
Pokémon Champions Timing History and Source Log
Current record: Season M-6 runs September 9, 2026 at 02:00 UTC through October 7, 2026 at 01:59 UTC under Regulation Set M-C. M-C remains active through December 2, 2026 at 01:59 UTC. Pokémon's September 2 preview confirms 24 newly available Pokémon and six added Mega Evolutions, Pokémon HOME's Regular Roster M-C notice lists all 29 roster forms, and the September 9 update added M-C Pokémon/items and battle features.
Why this history exists
Pokémon Champions schedules move quickly. A launch date, a maintenance window, and a ranked deadline can all be true at different times without being useful forever. This log makes that distinction visible. It records the source-backed change that affected the current timer rather than republishing a past event as a new answer.

Source and correction log
Pokémon's official M-C preview confirms that the September 9 update will make 24 Pokémon newly available and add six Mega Evolutions, naming Mega Salamence, Mega Golisopod and Mega Baxcalibur alongside the three Z Mega Evolutions. The full 24-name roster and ranked-season/Battle Pass mapping remain unconfirmed.
The official Ranked Battles Season M-6 notice confirms September 9–October 7 under M-C, and the M-6 Battle Pass notice confirms the matching pass window and rewards. The September Monthly Challenge uses M-C in Single Battles, while Global Challenge I uses M-C in Double Battles. Version 1.2.0 added M-C Pokémon/items and battle features.
Regulation Set M-C replaced M-B at 02:00 UTC. Pokémon HOME's Regular Roster M-C notice lists the complete roster forms (including regional and gender/plumage variants), and its lineup refreshes every 22 hours.
Reconfirmed that Season M-4 (ends August 5 at 01:59 UTC) and Regulation M-B (through September 2 at 01:59 UTC) remain current, no scheduled maintenance is listed in official news, and no official Season M-5 notice has been published. The M-5 window remains projected for August 5–September 2, and the Raichu gift deadline is unchanged at September 2 at 01:49 UTC.
Confirmed that Season M-4 and Regulation M-B remain current, no scheduled maintenance is listed, and no official Season M-5 notice has been published. Corrected the Raichu gift deadline to September 2 at 01:49 UTC and added Pokémon's July 24 M-B doubles overview as current strategy context.
Updated the live timer, Season M-4, Battle Pass, ranked reset, maintenance, and server-status pages to use the active ranked deadline rather than the June launch timeline. Source priority: official Pokémon July ranked and Battle Pass notice, with the official Champions news feed used for current service notices.
Season M-3 ended and the M-4 ranked window began. The timer now treats M-4 as confirmed. Earlier M-3 launch guides remain available as archives, but are not part of the current indexed guide set.
Regulation Set M-B started, and Pokémon Champions became available on iOS and Android. This was a launch milestone, not a perpetual current-status answer; its historical context is kept separate from the current maintenance and mobile-download guides.
Season M-1 began alongside the Nintendo Switch release. Later season end times are tracked separately because rank, Battle Pass progress, and regulations can change on different schedules.
How to read a projected date
A projected date is a planning estimate based on the last known season cadence. It is never used as an official claim. Pokémon's August 2026 events notice replaced the M-5 projection with its confirmed ranked-season window; this page records that source and the affected deadlines.
What this page does not do
This is not an official change log and it does not replace in-game notices, tournament rules, or Pokémon support. It is an editorial audit trail for this fan-made timer. Readers should use the cited official notice when a decision depends on an account, purchase, tournament entry, or live service incident.
