Pi Day is 14 March — 3/14 in month-day notation — celebrating the mathematical constant π. The next Pi Day is Saturday, March 14, 2026. The counter above shows the exact hours until it begins, at midnight (00:00) in your time zone.
How this is calculated
The countdown targets midnight (00:00) at the start of Pi Day in the selected time zone —always 14 March. That wall-clock time is resolved to an absolute instant, the current instant is subtracted, and the result is shown in hours. Working in absolute time means an interval that crosses a daylight saving change is an hour longer or shorter than the calendar suggests, and the number here reflects that.
The time zone is part of the link, so a countdown shared from one place shows the same hours everywhere. When Pi Day passes, the counter moves to the next one.
