The event begins Tuesday, November 16 at 10 am local time, and ends Sunday, November 21 at 8 pm. The event is divided into two halves, with each half focusing on each game. The first half runs from Tuesday to Thursday, and features more Pokémon from Diamond appearing in the wild, including Seel, Murkrow, and Poochyena.
The Pearl event begins directly afterward, ending on Sunday, and includes Pinsir, Misdreavus, and Hondour. Both event halves include hat-wearing versions of the starter Pokémon, Turtwig, Chimchar, and Piplup.
The event will feature its own raids, special 7km eggs, and field research encounters, including a chance to grab Burmy in different iterations. Throughout the event, you can also enjoy quicker incubators. Regular incubators will require half the distance, while super incubators only one third of the normal distance.
Finally, you can dress up you avatar in Sinnoh gear for free, including hat, pants, shoes, and backpack, or pay for full-body costumes inspired by the three Sinnoh starters.
