'Pokémon Go' Kanto Raid Day: Start Time, Counters and Everything You Need to Know On 2/27/21 at 7:00 AM EST Pokémon is celebrating the Kanto region for the franchise's 25th anniversary and it will cap off the festivities with a special Raid Day featuring Moltres, Articuno and Zapdos. The Kanto Raid Day event begins this Sunday and trainers will see all three Legendary Birds from Gen 1 in every Raid during the event-window. While the three Legendary Pokémon have been in the game for quite some time, trainers will get a chance to catch the Shiny versions of them as well as Shadow versions.
