With cool autumn nights quickly approaching in the Northern Hemisphere and sunny spring days arriving in the Southern Hemisphere, we thought it would be the perfect time to celebrate the coming equinox with an in-game event. New seasons mean new adventures!
From 1:00 P.M. PDT on September 22 to 1:00 P.M. PDT on October 2, 2017, you’ll have the opportunity to earn double Stardust for catching Pokémon and hatching Eggs as you walk around your neighborhood discovering new sights. While you’re out exploring, be sure to visit your local PokéStops and Gyms to collect special 2 km Eggs that have the opportunity to hatch Pokémon such as Chansey, Mareep, Larvitar, and more. You’ll also be able to get special boxes from the in-game shop that feature items like Lucky Eggs, Lure Modules, and all-new Super Incubators which hatch Eggs 1.5 times quicker!
