The other day, I was building a spreadsheet to calculate FTE (full time equivalent) for staff based on hours worked on various days in a fortnight. While building the spreadsheet, I came across an interesting problem. Rounding Time to nearest minute. We can’t use ROUND() or MROUND() to round time as these formulas aren’t designed to work with time values. Although time values are technically decimal, rounding time to nearest minute (or quarter hour etc.) can be tricky when usual round formulas. Let me share a few formulas to round time to nearest point.
Let’s say you have a time value (either user input or calculated) in cell A1.
Use below formulas to round time in A1.
Nearest second: =TIME(HOUR(A1), MINUTE(A1), SECOND(A1)).
- SECOND formula rounds up any fractions and returns full seconds.
Nearest 15 seconds: =TIME(HOUR(A1), MINUTE(A1), MROUND(SECOND(A1),15))
- Use MROUND() to round up seconds values to nearest multiple of 15 (or whatever else)
Nearest Minute: =TIME(HOUR(A1), MINUTE(A1)+(SECOND(A1)>30),0)
- The seconds value will always be zero. We just look at fractional minutes portion to see if they are more then 30 to round up to next minute. The trick is to add up Boolean check (SECOND(A1)>30) to minutes value.
Nearest 15 minutes: =TIME(HOUR(A1), MROUND(MINUTE(A1)+SECOND(A1)/60,15),0)
- This one uses MROUND to round total mins (including fraction) to nearest multiple of 15.
Nearest 37th minute: =TIME(HOUR(A1), MROUND(MINUTE(A1)+SECOND(A1)/60,37),0)
- Same logic. Just to show you how to round to an arbitrary minute.
Nearest hour: =TIME(HOUR(A1) +((MINUTE(A1)+SECOND(A1)/60)>30),0,0)
- Check if total minutes is greater than 30 and add the result to hours.
Time for some home work
Let’s test your timing skills. Assuming A1 has date & time value (like 26-Jun-2017 7:21:32 AM), round it up to nearest working hour.
- The working hours are 9AM to 6PM on weekdays (Monday – Friday)

Ciao Hui,
Collecting Excel tricks under the title “Notable Excel Websites (Non-MVP) Edition” is a brilliant idea…
Thank you in the name of all The FrankensTeam.
On our site there is a box with a picture and text highlighting:
This is a no-MVP site
we think ourselves “bad boys” a bit 🙂
For those who would like to know why our site is a no-MVP site, enough to click on the link:

Thank you again!
Thanks a lot
I really enjoyed this (newsletter). I must admit that I rarely read an Excel newsletter (and I subscribe to quite a few) all the way though, but this grabbed my attention and before I realized it, I was engrossed in it. I must also admit that most of this I don’t understand, yet. But, it excites me when I do learn something new in Excel. I can’t wait to see how much of this I can implement into my (constantly-evolving) ‘House Budget’ & ‘Family Medical’ worksheets that I have developed over the past few years! I sure hope to see more of these type of newsletters in the future! Thanks!
Thanks for doing this Hui! I appreciate being included.
I like Tom’s tip a lot. I posted about a tool I wrote to automate this at http://yoursumbuddy.com/tables-edit-query-dialog/
EXCELLENT !
Hui, This post is Superb! More over I have always been a fan of Roberto’s work and have learnt a lot from him.

I like the Excel Ninja Menus.
1. Select a cell or range then move till the 4-way cross appears. Right-Click and drag the selection to another place in the worksheet then, like a ninja, a menu full of skills and throwing stars pops up allowing me to do all kinds of awesomeness.
2. When you click the fill box on a Date and right click and drag it down, a lot of amazing Date options pop up.
I also brand my Excel to remind myself that I’m awesome. In my personal macro workbook I place the following code.
Private Sub Workbook_Open()
Application.Caption = “SuperKrishna’s Awesomeness”
End Sub
My favorite tip goes along with #17. If you try to copy subtotaled data (and in earlier Excel versions filtered data),when you paste it all the data displays instead of just the summarized data.
To get around this, select your summarized data, click on Find and Select tab and then select Go to Special. Click Visible cells Only and click OK. Now paste and you will see that only the summarized data has been copied.
You can also go CTRL+G and then click the Special icon at the bottom of the dialog box.
What a great idea, Chandoo! I’d love to be included in your next edition:) Perhaps a VBA exclusive version?
@Ryan
I will review this concept about 6 months out from the original post and be sure to keep your site in mind
Hui…
That sounds great, Hui:) I just realized I gave credit to Chandoo for the idea and I should have attributed it to you.
Sorry about that!
