The next Pokemon Go Community Day will take place on April 13, 2019 and will feature the dragon-type Pokemon Bagon! The event will also feature three-hour lures and triple catch XP. The exclusive move is yet to be announced.
The event will take place from 3:00pm to 6:00pm based on your local time. You still have an extra hour to evolve Bagon or Shellgon into Salamence and get the exclusive move.
