Niantic has announced Pokémon GO Community Day's. It is designed to be a day where players around the world meet up in a real-world location to play the game and meet new friends.

Introducing Pokémon GO Community Day!

Trainers, We’re incredibly excited to announce Pokémon GO Community Day–a monthly worldwide event dedicated to celebrate you, the Trainers in the Pokémon GO community.

What is Pokémon GO Community Day? Pokémon GO Community Day is an opportunity for Trainers around the world to meet up at their local parks to make new friends and experience what it means to be a part of this special community.

Once a month, we’ll host a Pokémon GO Community Day event starring a special Pokémon, which will appear frequently around the world for just a few hours. When caught during the event, this special Pokémon will know an exclusive move. Other bonuses will be in effect during the event, such as increased XP or Stardust, and Lure Modules activated during the event will last for three hours.

We’re constantly blown away by the passion of Pokémon GO players around the world, and we hope that each Pokémon GO Community Day will help add to the excitement of local events and meetups. Remember always to be alert and stay safe while playing and to be respectful of public spaces when exploring your community. Stay tuned to our social media channels and check out the Pokémon GO Community Day event page each month to learn about that month’s featured Pokémon, special bonuses, and event times.
