Below is the description for Pokemon Go Community Days.

Get out and play together in your local community parks on Pokémon GO Community Day. For just a few hours each month, you can encounter a special Pokémon in the wild. During these hours, there’s a chance to learn a previously unavailable move for that Pokémon or its Evolution, as well as earn some Community Day bonuses. Celebrate what it means to be a part of the Pokémon GO community and make new friends along the way!

Note: Fast TMs and Charged TMs will not grant exclusive moves during Community Day. To learn the exclusive move, you must catch or evolve the featured Pokémon during Community Day hours.
