What is Groundhog Day?
Groundhog Day is 2 February, when Punxsutawney Phil is brought out in Pennsylvania and a shadow is said to mean six more weeks of winter. The custom arrived with German settlers and attaches to Candlemas, an older marker of the midpoint between the winter solstice and the spring equinox. Its forecasting record is no better than chance. The date is fixed and it is not a public holiday, so this countdown rolls straight to next year once 2 February has passed.
The event itself is short and very early. The ceremony at Gobbler's Knob takes place around sunrise, which means visitors arrive in the middle of the night, and the town fills well beyond its usual size. Other towns run their own versions with their own animals, and the predictions frequently disagree with one another in the same year. The 1993 film attached the phrase to the idea of a day repeating, and that meaning is now more widely known than the custom, which is worth remembering before naming a recurring meeting after it. Because 2 February is also Candlemas and a marker of midwinter, several European weather sayings attach to the same date with no animal involved. Nothing closes, and in most of the world the date passes without comment.
Canada runs versions of its own, with Wiarton Willie in Ontario and Shubenacadie Sam in Nova Scotia, and their verdicts are announced within the same hour as Pennsylvania's. In Germany the older form of the custom watched a badger rather than a groundhog. France and Belgium keep the same date as Candlemas and mark it by eating crepes, with a coin held in one hand while the first is flipped. The arithmetic people get wrong is the six weeks: counted from 2 February they end in the middle of March, before the equinox rather than at it, so even a shadow does not stretch winter to the astronomical date.
The next one falls on Tuesday, 2 February 2027, and this page counts down to the midnight that starts it in whatever time zone your browser reports.
