Calendar encounters

The game changes a land encounter slot in certain places on these annual dates, using the game’s calendar. These entries were verified in v4.0.3’s encounter-loading code; successful captures and interactions with every other encounter modifier have not been replayed.

They replace the final land slot, normally weighted 1% of land encounters, while keeping its existing level. That is not a 1% chance per step or a verified shiny/visible-spawn probability. They do not replace Surf or fishing slots. Reloading the map is the conservative way to let the encounter table refresh after a date change; changing the clock while staying on a map has not been tested.

Morning: 04:00–09:59. Day: 10:00–19:59. Night: 20:00–03:59. The month and day must still match: July 18’s night window does not extend into July 19.

Date	Pokémon	Place	Time / level	What is known
April 16	Volcanion	Lake of Rage	All day	Not an acquisition route. No usable land encounter from this entry: the location has a zero land encounter rate. It does not add a Surf encounter.
June 23	Keldeo	Fuchsia City — Koga's forest preserve	All day · Lv. 5	Configured encounter. The forest preserve only; not every part of Fuchsia City.
July 14	Meloetta	Ilex Forest	All day · Lv. 6	Configured encounter. Replaces the final land encounter slot.
July 18	Hoopa	Mt. Silver — exterior	Morning only · Lv. 50	Configured encounter. 04:00–09:59. Neither Hoopa entry applies during the daytime period.
July 18	Hoopa Unbound	Mt. Silver — exterior	Night only · Lv. 50	Configured encounter. 20:00–03:59, while the calendar date is July 18.
July 19	Diancie	Island Forest	All day · Lv. 17	Needs verification. The configured form is unresolved. This is not a confirmed capture route or a verified Mega Diancie encounter.
August 11	Genesect	Ruins of Alph — exterior	All day · Lv. 5	Configured encounter. The exterior only; not the puzzle chambers.
October 16	Floette (Eternal Flower)	National Park	All day · Lv. 14	Configured encounter. The normal park encounter table; not a verified Bug-Catching Contest encounter.

Entries that need care

Diancie: the encounter specifies a form that could not be resolved from the normal form table. Do not treat it as a confirmed way to catch Diancie or Mega Diancie.

Volcanion: the April 16 entry modifies a land slot at Lake of Rage, where the land encounter rate is zero. Both ordinary land encounters and fresh visible land spawns reject that source. It is listed so the configured entry is not mistaken for a usable catch location.

These entries are separate from the Wednesday Lake of Rage events and from visible encounters and shiny retention.
