Are you struggling to calculate time in Excel? This article will show you how to utilize formulas to easily calculate time and make your workflow more efficient. You’ll soon be an Excel expert!
Understanding the Excel time format
Recognize that Excel stores dates, times and durations as numbers. It starts counting from January 1st, 1900. Each day has its own number. For example, “0.5” stands for noon or half of the day. Format cells correctly to make sure they recognize data as time values.
Be aware of some limitations, such as Excel won’t recognize negative durations. Plus, wrong formatting can lead to errors.
Nevertheless, understanding the Excel time format can improve managing schedules, project timelines, payroll hours, etc. A study found that companies who track employee working hours with Excel increase their efficiency by 33%.

Adding and subtracting time in Excel
Type your time values into the cells or use a formula.
Select the cell where you’d like the result to be.
Use either the SUM or SUBTRACT function followed by the cells containing your values. For example, if you want to add two times =SUM(cell1, cell2).
It’s important to use a specific format when entering time values into Excel. The standard format is hh:mm:ss. If your times exceed 24 hours, you may need to format the cells as [h]:mm:ss.
Remember that Excel stores dates and times as serial numbers. January 1st, 1900 has a serial number of 1. Every date and time since then has its own unique serial number. This allows for easy calculation of elapsed time between two points by subtracting one serial number from another.
Fun Fact: Excel can handle up to 10,000 days! That’s equal to around 4 million seconds!
Stay tuned for our next guide on calculating the difference between two times in Excel.
Calculating the difference between two times in Excel
To calculate the difference between two times in Excel, take these steps:
- Select the cell where you want your answer to appear.
- Type =end_time-start_time, replacing “end_time” with the later time value and “start_time” with the earlier time value.
- Format the cell as “Time”.
- Press “Enter” and the answer should appear!
- Make any customizations as needed.
When calculating the difference between times in Excel, keep these tips in mind:
- Consistent time format across all cells.
- Consider different dates when calculating differences between times.
Calculating the difference between two times in Excel is a useful skill. Practice this process until you find what works best for you. Finally, learn more about finding the total time between two dates in Excel!
Finding the total time between two dates in Excel
Open Excel and make two columns – one for the start date and one for the end date. Fill the dates in mm/dd/yyyy format. In the third column, subtract the start date from the end date using ‘=enddate-startdate’. The result will be a decimal number of days. However, you can convert it to hours, minutes, or seconds by multiplying by 24, 1440, or 86400 respectively. If the result is too complicated, use Excel’s formatting options to make it readable. Label the columns to remember the dates and units of your result.
Calculating time differences in Excel is a useful way to save time and avoid errors. Ensure the inputs are correct before running any formula. An example of an error is when someone swapped the start and end dates – that caused the employee to report negative hours!
Advanced time calculations in Excel include functions to calculate sums/averages of times, conditional formatting for dates, and creating Gantt charts for project schedules. With these techniques you can become even more efficient at working with time-related data.
