Groundhog Day takes its name from the February 2 holiday in North America, when a groundhog is said to predict the end of winter, most famously in Punxsutawney, Pennsylvania. The phrase became a lasting pop culture shorthand after the 1993 comedy Groundhog Day, starring Bill Murray as a weatherman forced to relive the same day over and over. Online, that meaning stuck, so the shout is now used whenever work, school or a video edit feels stuck in an endless repeat.
