Subtracting Time Intervals

There are many situations in life when subtraction of time intervals is required. Whether it’s calculating the duration of flights, estimating travel times between destinations, or planning activities during a trip, the ability to subtract time intervals ensures that travelers make the most of their time and experience a well-organized itinerary.

Event management greatly benefits from the ability to subtract time intervals. Event planners can accurately allocate time slots for various sessions, speakers and breaks by calculating the duration between the start and end times of the event.

In data analysis, subtracting time intervals is a powerful tool for extracting insights from time-based datasets. Analysts can calculate the time between events, such as customer interactions, website visits, or product cycles, to identify patterns, trends, and correlations.

How to Subtract Times

To subtract times or time intervals, the following simple algorithm can be used.

1) First, we must convert all the times to a single unit of measurement. In our online calculator, this unit is the second.

2) Next, we subtract the times expressed in seconds.

3) Now, to represent the difference in the standard format HH:MM:SS, we divide the result by 60 (the number of seconds in a minute) and take the remainder of this division as the number of seconds of the desired difference.

4) The quotient of this division we will again divide by 60 (the number of minutes in an hour). We take the remainder of this last division as the number of minutes of the desired difference.

5) And finally, the quotient of this last division will be the number of hours of the desired difference.

Manual calculations using the above algorithm are not a big problem. However, such calculations can be time-consuming and prone to errors. Therefore, it is much easier to use our Subtract Time Calculator instead.
