The next Pokemon Go Community Day will take place on September 15, 2019 and will feature the grass-type Pokemon Turtwig! The event will also feature three-hour lures and triple stardust on captures. The exclusive move is yet to be announced.
The event will take place from 11:00 am to 2:00 pm based on your local time. You still have an extra hour to evolve Turtwig or Grotle into Torterra and get the exclusive move.
