Pokemon GO has announced a brand-new limited time event set to run during the weekend of December 16 and 17, allowing players to catch up on past Community Days. The monthly Community Day events have become a staple of the schedule for the massively popular mobile game, featuring increased spawns of specific Pokemon. The events also feature an increased rate for finding Shiny Pokemon, as well as special bonuses when powering up the featured creatures. Now, Niantic is giving players a chance to catch up on this year's Community Day Pokemon.
