How to Round to the Nearest Quarter Hour in Excel

Time is a crucial element in our daily lives, and it is essential to keep track of it accurately. Excel is a powerful tool that can help you manage your time effectively. One of the most common tasks in Excel is rounding time to the nearest quarter hour. In this article, we will show you how to do this in Excel.

Step 1: Convert Time to Decimal

The first step is to convert the time to decimal format. Excel stores time as a fraction of a day, where 1 represents 24 hours. To convert time to decimal, you need to multiply the number of hours by 24 and the number of minutes by 1440. For example, if you have a time value of 2:30 PM, you would multiply 2 by 24 and add 0.5 (30 minutes divided by 60 minutes) to get 2.5.

Step 2: Round to the Nearest Quarter Hour

Once you have converted the time to decimal format, you can use the ROUND function to round it to the nearest quarter hour. The ROUND function takes two arguments: the number you want to round and the number of decimal places to round to. To round to the nearest quarter hour, you need to round to two decimal places.



For example, if you have a time value of 2:30 PM, which is 2.5 in decimal format, you would use the following formula:


This formula will round the time to the nearest quarter hour, which is 2:30 PM.

Step 3: Format the Cell

Finally, you need to format the cell to display the time in the correct format. To do this, select the cell and go to the Home tab. Click on the Number Format dropdown and select Time. Choose the format that displays the time in the way you want it to be displayed.


Rounding time to the nearest quarter hour is a common task in Excel, and it can be done easily using the ROUND function. By following the steps outlined in this article, you can ensure that your time is always accurate and rounded to the nearest quarter hour.
