Hours until tomorrow begins — midnight tonight in your time zone. The counter above shows the exact hours until it begins, at midnight (00:00) in your time zone.
How this is calculated
hours until tomorrow = (start of tomorrow in the chosen zone − now) ÷ 3,600 s
The countdown targets midnight (00:00) at the start of tomorrow in the selected time zone —midnight at the start of the next day. 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 tomorrow passes, the counter moves to the next one.
