Easter is a seasonal event in Cookie Clicker. It was added on May 18, 2014, with the 1.0464 update. Since the 1.0466 update, Easter starts automatically and lasts from 7 days before Easter (Palm Sunday) to Easter itself (Easter Sunday). Easter can also be activated by purchasing the Upgrade "Bunny biscuit", which will launch it for 24 hours. The Bunny Biscuit Upgrade becomes available after unlocking the "Season switcher", The upgrade is repeatable, but it gets more expensive each time it is bought. When activated, It cancels any other seasonal event.
