The easter event was just announced by Niantic. Most notable thing is the Double XP and more variety of rare Pokemon on the 2KM eggs.
Lace up your walking shoes and get ready to put a spring in your step—the Pokémon GO Eggstravaganza is nearly here! From 1:00 P.M. PDT on April 13 to 1:00 P.M. PDT on April 20, 2017, a greater variety of Pokémon can now be found in 2 km Eggs, so get cracking and see what you find! Your Egg-venture doesn’t stop there, though—you’ll also earn more Candy for every Egg you hatch!
Throughout this Eggstravaganza, you’ll also level up even faster with double XP! Combine this Egg-cellent bonus with a Lucky Egg, and you’ll earn four times the XP you normally would. To make this Eggstravaganza even sweeter, Lucky Eggs will be 50% off in the in-game shop!
Get out there, hatch some Eggs, and share your stories with us using #PokemonGO on your favorite social media channels.
