The Adamant Time event will take place in Pokémon GO from Monday, December 11th, 2023, at 10:00 a.m. to Friday, December 15th, 2023, at 8:00 p.m. local time and features Pokémon originally discovered in the Kanto region.

Catch up in time for the Adamant Time event, and party up in a Kanto comeback!

Trainers,
No need to take a trip back to where it all started in the Kanto region—it appears that the Kanto region has come to us across time and space! The year may not be 2016, but Pokémon originally discovered in the Kanto region are inexplicably roaming the wild in greater numbers than before.

Spend some time researching with Professor Willow, and shine a light on these latest developments! In the meantime, what better way to study these Pokémon than interacting with them in new ways? Party up, explore a Route, and enter your stars in a PokéStop Showcase!
