Time Between Times Calculator
Find the duration between two clock times.
The gap between two times
Working out how long is between two clock times is a constant need for timesheets and shifts, and the overnight case trips people up. This calculator handles both, midnight crossing included.
From 9:00 to 17:30 is 8 hours 30 minutes, or 8.5 decimal hours. If the end time is earlier than the start, it assumes an overnight span and adds a day automatically.
