Earth Day is 22 April, an annual event in support of environmental protection first held in 1970. The next Earth Day is Wednesday, April 22, 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 Earth Day in the selected time zone —always 22 April. 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 Earth Day passes, the counter moves to the next one.
