Time Duration Calculator
The Time Duration Calculator works out the hours, minutes, and seconds between two times, including overnight shifts and deductions for breaks.
Time math without the headache
Enter a start and end time and it returns the elapsed duration in hours and minutes. It correctly handles times that cross midnight (a shift from 22:00 to 06:00 is 8 hours, not a negative number), which is exactly where manual calculation trips people up.
Great for timesheets
Subtract an unpaid break and it gives net working hours, making it handy for logging shifts, billing clients by the hour, or timing an activity. For durations measured in whole days rather than hours, use the Date Duration Calculator.
Frequently Asked Questions
Can it handle overnight time spans?
Yes. If the end time is earlier in the clock than the start, it treats it as crossing midnight and returns the correct positive duration.
Can I deduct a break?
Yes. Enter a break length and it subtracts it to give the net hours, ideal for timesheets.
Does it show seconds as well as minutes?
Yes. It can express the duration in hours, minutes, and seconds.
Is it good for billing by the hour?
Yes. The net-hours result makes it easy to log worked time and bill clients accurately.
