Aired Date (Original Air Date)

21 Groups, 1272 Episodes

I tried my best to add the episodes to their season groupings as they are listed on TVDB. Things are a bit wrong in here.

Absolute Order (Absolute)

1 Group, 1279 Episodes

Every episode in order without the division of seasons.

Pokémon TV (US) (Digital)

25 Groups, 1220 Episodes

In this order, the episodes are organized based on the current listing on the official Pokémon Episode Encyclopedia website. It does not include episodes that have been dubbed and aired but have been removed from rotation ("Beauty and the Beach", "Holiday Hi-Jynx", "Stage Fight", "The Mandarin Island Miss Match"). The official count is one episode short due to the "Pokémon Ranger - Deoxys' Crisis" being listed on the official Japanese website as a single, double-length episode instead of the two-part episode that appears on the Pokémon Episode Encyclopedia.

Chronological Order of Official Counting (Story Arc)

7 Groups, 1245 Episodes

This listing is built around the Japanese series division, episodes in chronological order of events, and the inclusion of major specials that aired in the show’s regular time slots (the end-of-series specials focusing on Ash’s friends and the Mega Evolution Specials aired during the XY series). Basically, it has everything that's included in the official counting announced by TV Tokyo, but with the correction of the chronology of the episodes that were aired out-of-order. Doesn't include episodes that were never aired. Also, even though the "Pokémon Ranger - Deoxys' Crisis!" episode is a two-parter, it's listed as a single special here on TMDB, so if for some reason you notice there's an episode missing in the AG series, that's why. Other than that, the only things missing at the moment for this list to be 100% are the two end-of-series specials of the Diamond & Pearl series, which are neither currently listed as regular episodes or specials.
