| - Business Day is a seasonal event in Cookie Clicker, added in version 1.0413. This season serves as an April Fools' Day prank, using the business theme as a practical joke. Since version 1.0466, Business Day starts automatically on the 31st of March, and lasts until the 2nd of April (30th of March to 1st of April on a leap year). Business Day can be activated at will by purchasing the season switch upgrade "Fool's biscuit", which enables the season for 24 hours. The upgrade will unlock after purchasing the Season switcher for 1,111 Heavenly chips, which lets the player trigger seasonal events at will. The upgrade is repeatable after expiring, though it doubles in cost each time a season switch upgrade is activated. Additionally, activating the season will end the current season, if one is in play. When the season is active, the cosmetic effects of the season activate immediately. This includes a new dollar bill-themed background, dollar bill particle effects replacing the cookies falling in the background and appearing when clicking the Big Cookie, new news ticker messages (which appear in place of all other ticker headlines), and Golden Cookies taking the appearance of contracts. By default, Business Day only features one major gameplay change, which is an exclusive Golden Cookie effect called "Everything must go", which reduces the cost of all buildings by 5% for 5 seconds of base time. If the heavenly upgrade Startrade has been purchased, Golden Cookies appear 5% more often during Business Day. If the Pantheon god Selebrak is slotted, Golden Cookies appear slightly more often during Business Day than in other seasons.
