How This Works
This tool measures elapsed time from a clock time earlier today up to right now, updating live every second. If the time you enter hasn't happened yet today, it will say so rather than showing a negative duration.
Formula
Elapsed Time = Current Time − Past Time
Example
If it's currently 3:45 PM and you entered 9:00 AM, the elapsed time shown is 6 hours 45 minutes and counting.
