Calculating time differences and durations in Google Sheets is a straightforward process that can significantly enhance your productivity and time management skills.
In this blog, I’ll guide you through the steps and formulas needed to perform these calculations efficiently. Learn to effortlessly track hours worked, project timelines, and event durations within the versatile environment of Google Sheets.
Calculating Time Differences
To find the differences between two times, you can simply subtract one from the other. Google Sheets stores times as serial numbers, making subtraction straightforward.
Here’s a basic formula: =End Time-Start Time
Suppose your start time is in cell A2, and your end time is in cell B2.
You want the difference in cell C1: =B2 – A2
For formatting for Hours:Minutes, select the cell with the formula, then go to Format>Number>More Formats>Custom number format.
Enter “hh:mm” to display the result in hours and minutes.
If you want to see the difference in hours only, you can use a different format: =INT((End Time – Start Time) * 24)
Calculating Durations
If you want to calculate the duration of a single time entry, such as how many hours are in a given time value– essentially converting time to a number– you can use =HOUR, =MINUTE, and =SECOND functions.
Suppose you have a spreadsheet where you want to calculate the duration of a single time entry in decimal hours.
You can use the following formula to calculate the duration in decimal hours: =HOUR(A2) + MINUTE(A2)/60 + SECOND(A2)/3600
If you have multiple time entries and you want the total duration in hours: =SUM(HourRange) + SUM(MinuteRange)/60 + SUM(SecondRange)/3600
Replace HourRange, MinuteRange, and SecondRange with the ranges where your hour, minute, and second values are stored.

In conclusion
With an understanding of time formats, the right formulas, and functions, you can effortlessly compute time differences and durations, format results, and manage time zones effectively.
So, the next time you’re faced with time-related data, rest assured that Google Sheets has the tools you need to tackle it with confidence.
Frequently Asked Questions
How do I track duration in Google Sheets?
You can use a simple subtraction formula to track duration in Google Sheets, where the earlier time is subtracted from the later time.
Ensure that your time values are correctly formatted (e.g., “HH:MM:SS”) and simply use the formula =End Time – Start Time.
How do I add and subtract duration in Google Sheets?
Adding and subtracting durations in Google Sheets can be accomplished using the “+” or “-” operators with time values.
To get accurate results, remember to format the cells correctly as either time duration or custom (in HH:MM:SS format).
How do I calculate productive hours in Google Sheets?
By deducting non-productive hours (like break times) from the total number of working hours, one can calculate productive hours in Google Sheets.
Input your starting time, ending time, and break duration, then subtract the break duration from the difference between the ending and starting times.
