The scheduled window opens September 9, 2026, at 02:00 UTC and closes December 2, 2026, at 01:59 UTC. This page converts both endpoints to your device's local time beside the UTC values, so there is no timezone arithmetic to do by hand.
Evidence: EV-MC-RULE-816
The eligible list was recounted from the official page itself: 262 form entries covering 231 distinct national Pokédex numbers. Twenty-five of those entries, including Salamence and Golisopod, are not yet present in this site's attribute dataset, so they cannot be selected in the builder until the data is updated. They remain eligible under the published rules.

The published clauses are simple and strict. A team may Mega Evolve once per battle, and the Pokémon must hold its Mega Stone. Two Pokémon on a team may not hold the same item. Match timers are 20 minutes total, 7 minutes per player, 45 seconds per turn, and 90 seconds of preview time. The announcement newly allows six Mega Evolutions: Mega Absol Z, Mega Salamence, Mega Garchomp Z, Mega Lucario Z, Mega Golisopod, and Mega Baxcalibur.

Known limits, stated plainly: the official page does not publish a level rule, a species clause, or per-move and per-item legality lists, so this site does not invent them. Form attributes come from PokéBase, an authorized third-party source, not from Nintendo or The Pokémon Company. No usage or popularity data exists for this regulation anywhere on this site.
