How This Works
This tool counts down live to the next occurrence of the time you enter — today if it hasn't happened yet, or tomorrow if it already has (or if it exactly matches the current moment).
Formula
Time Until = Target Time − Current Time (+ 24 hours if the target already passed today)
Example
If it's currently 2:15 PM and your target is 5:00 PM, the countdown shows 2 hours 45 minutes and ticks down from there.
