Time Until Calculator

It counts down from the current moment to any clock time you choose, showing exactly how many hours and minutes remain. Pick an hour, a minute and AM or PM, and it displays the time left until that moment.

The countdown goes to the next real moment your clock shows that time: later today if it is still ahead — on the night clocks go back, the repeated hour counts too — otherwise the next day that has it; if the clocks skip that time tomorrow, the day after.

The countdown runs in your own time zone: the page reads it from your browser, and you can pick a different one right under the answer. With JavaScript turned off the page falls back to Coordinated Universal Time (UTC) and says so next to the result.
