In-depth explanation
Enter a start and end time to see the exact difference in hours, minutes, and seconds. Use “Ends next day” for overnight shifts that cross midnight. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
Enter the start and end times, then turn on “Ends next day” so a range like 22:00 to 06:00 is treated as 8 hours. Use the time inputs (with seconds where supported) for a precise duration.
For full calendar spans use Days Between Dates or Countdown To Date. This tool focuses on clock times within a day (or overnight). Tweak the inputs above to compare options, then copy or note the result you need.
