Pokémon Go's April Fool's event returns again 1 April 2021 · News Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Niantic (Pocket-lint) - April Fool's might be a time-honoured tradition, but it's also generally a bit of a risky area for brands - only a carefully planned joke can avoid any ill-will if it's aimed wrong. Pokémon Go has taken a different route in recent times, eschewing jokes entirely. Instead, it has an annual April Fool's event that comes around for a day each year, and it's back for 2021. It runs all day on your local time, and means that your routine might be a little different to normal.
