What this calculator is useful for

Find elapsed hours and minutes between two clock times, including overnight intervals. The result is intended for quick estimates, checking arithmetic and comparing scenarios. When a result affects a contract, tax filing, medical decision, building-code requirement or other high-stakes situation, verify the result with the appropriate professional or authoritative source.

9:00 AM to 5:15 PM: 8 hours 15 minutes

The elapsed interval is 8 hours 15 minutes, which is 8.25 decimal hours. This example does not subtract a lunch break.

How to interpret the result

Use elapsed time for appointments or shifts with no unpaid break, then switch to Work Hours for break deductions.

Important limitation

An end time earlier than the start is treated as the next day; the tool does not calculate spans longer than one day or time-zone changes.
