How do you calculate time duration between two times?

Time duration is calculated by subtracting the start time from the end time. If the end time is earlier on the clock than the start time (e.g., 10 PM to 2 AM), the calculation assumes the end time is on the next day. The result can be expressed in hours and minutes, total hours (decimal), or total minutes.

Can I calculate duration across multiple days?

Yes, time duration calculators can handle periods spanning multiple days. Simply specify both the date and time for the start and end points. The calculator will account for all intervening days, including overnight periods, to give you the total elapsed time in days, hours, and minutes.

How do I add or subtract time durations?

To add time durations, sum the hours and minutes separately, then convert any excess minutes (60+) into hours. To subtract, convert everything to minutes, perform the subtraction, then convert back to hours and minutes. Advanced calculators can handle multiple time duration operations in sequence.

What's the difference between duration and elapsed time?

These terms are often used interchangeably. Both refer to the amount of time that passes between two points. 'Elapsed time' emphasizes the continuous passage of time, while 'duration' may refer to the length of an event. Practically, they mean the same thing for calculation purposes.

How do I calculate work hours excluding breaks?

First calculate the total time duration from clock-in to clock-out, then subtract the length of any breaks or lunch periods. For example, working from 9 AM to 5 PM (8 hours) with a 30-minute lunch equals 7.5 hours of actual work time. Multiple breaks should be summed before subtracting.
