소개

Countdown Calculator — Days, hours, minutes and seconds until any future date and time. Enter Target date/time, Count from (leave blank for now), Time zone of the date/times above to get an instant, accurate result.

공식

The target (and optional "count from") date/time you type is interpreted in the time zone you select (pre-selected from your device, changeable; an offset typed in the date itself overrides it). The result is the elapsed time between those instants, split into days/hours/minutes/seconds, plus total hours and total minutes. The result shows how your input was interpreted, including the equivalent UTC time.

What happens after the target date passes?
The countdown flips to show the elapsed time since the target, flagged as already past rather than upcoming.
Does it account for leap years, month lengths and daylight-saving changes?
