How to Use the Elapsed Time Calculator
Enter a start time and an end time and this tool instantly calculates the elapsed time between them in hours and minutes. Whether you're logging work hours, tracking a workout, or figuring out how long a task actually took, you get the answer immediately without doing the subtraction by hand — including handling the 60-minute carry that trips people up when subtracting clock times manually. The total elapsed minutes are also shown, which is handy for payroll or any calculation that needs a single minute-based number.
If the end time is earlier than the start time — say a shift that starts at 11 PM and ends at 7 AM the next morning — the calculator automatically treats it as crossing midnight and adds 24 hours before computing the difference. That makes it especially useful for overnight shifts, red-eye travel, or any time span that spans two calendar days.
You can recheck multiple time spans in the same day just by changing the start and end fields. See the FAQ below for more detail on exactly how the calculation works.
