Pokemon GO's December 2021 Community Day really promises to be something special. While tons of Community Days throughout the game's history have put all kinds of precious Pokemon in the spotlight, in December 2021, Niantic will crank up encounter rates for a large list of Pokemon previously featured in 2020 and 2021's previous Community Days and spread the event across two days instead of one. The result is a delightfully diverse Community Day and a valuable opportunity to catch a plethora of uncommon and rare Pokemon in Pokemon GO. Fans will be greatly encouraged to gather all the Candy they can and hunt for Shiny variants.
