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 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. For a date of your own, the deadline countdown takes any target and tracks progress against it.
