Pokemon Go: Everything You Need to Know About December's Community Day Event Pokemon Go's final Community Day of the year takes place this weekend. Unlike normal Community Day events, which last for a few hours on one day and focus on one Pokemon species, this weekend's Community Day event is a two-day mega-event that brings back every Pokemon species that got a Community Day over the last two years. Over 20 species will be featured in December's Community Day event, which starts December 12th at 6 AM and runs through December 13th at 10 PM, and all of those Pokemon can learn their exclusive Community Day moves. This weekend's event is a great chance to grab some Shiny Pokemon, add a few powerful Pokemon to your collection, and take advantage of some extra bonuses to build up your Stardust reserves.
