How to average timestamps of day in Excel?

For example, you have recorded the login timestamps of every time a specific user accessed a website in Excel as following screen shot show, and now you want to average these timestamps for predicting the most possible time this users will access the website in future, how could you get it done? Here I will introduce two ways to average timestamps of days in Excel.

Average timestamps of days with a help column in Excel
Average timestamps of day with an array formula in Excel

Average timestamps of days with a help column in Excel

We can calculate the time of every day in a help column, and then average the time in the help column easily in Excel. You can do as follows:

1. Besides original Timestamps column, type the word “Time” into the Cell B1, enter =A2-INT(A2) into Cell B2, and then drag its Fill Handle to the Range B2:B6. See screen shot:

Note: In the formula of =A2-INT(A2), A2 is the first timestamp in Timestamps column, and you can change it based on your needs.

2. Keep selecting the time cells in the help column, and then format them as time with clicking the arrow  in Number Format box > Time on Home tab. See screen shot:

3. Select the blank cell below help column, in our case select Cell B7, enter the formula =AVERAGE(B2:B6) into it and press the Enter key.

Now you will get the average time of these timestamps of days at once.

One click to batch convert multiple time to hours/minutes/seconds without multiplying 24/1440/86400

For example you have a time of 2:23:42, you can convert this time to hours by multiplying 24 (or multiplying 1440 to minutes, multiplying 86400 to seconds; in other words, we can apply the formula =F2*24 for converting the time to hours,  =F2*1440 to minutes, =F2*86400 to seconds), and then change the formula cell to Number format. But, with Kutools for Excel ’s Convert Time utility, you can one click to batch convert multiple time data to hours/minutes/seconds only in Excel. Full Feature Free Trial 30-day!

Average timestamps of day with an array formula in Excel

Actually, we can apply an array formula to average timestamps of days directly in Excel. You can do as follow:

1. Select any blank cell, says Cell B4, enter the formula =AVERAGE(--TEXT(A2:A6-INT(A2:A6),"h:mm")), and then press the Ctrl + Shift + Enter keys simultaneously.

I have used =INT(B5-A5)&" Days "&HOUR(MOD(B5-A5,1))&" Hour "&MINUTE(MOD(B5-A5,1))&" Minutes" to find the days, hours and minutes between 2 dates. Now I need to find the average of all the days, hours and minutes. I'm having a hard time coming up with an AVERAGE formula that will work with my previous formula. Please help!
