Rounding time to nearest minute or quarter hour etc. [formulas]

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.

round-time-in-excel

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)

    As far as I remember (checked, again, 2 minutes ago) in my "Excel 2013" in order to select various chart elements I need to use the Arrow keys and not the TAB key.
    Practically, the TAB key does nothing (within a Chart).

      Thanks for pointing this out. This is how I remember it too, but when I was recording the video yesterday, only TAB key worked. MS must have changed the keys in Excel 2016. I have edited the post to include both keys.

      • Andy Pope says:

        The key navigation on charts is different in 2016.

        TAB cycles through a layer of objects (SHIFT+TAB cycles backwards)
        ENTER move down a layer
        ESC moves up a layer

        So on a column chart with title/legend/data labels if you select the plotarea the TAB will go through Title > Legend > Plotarea.
        ENTER at plotarea will then select Vertical axis. Tab will take you through
        Horizontal axis > gridlines > Series > Horizontal Axis.
        ENTER with series selected will then allow you to TAB through individual data points and data labels.
        If you ENTER on datalabels you can TAB through each data label.

    ALT + F1 : to create default chart
    ALT+E S T = CTRL + ALT + V, T : I find that easier to remember

    I second what Michael already said about TAB and arrow keys. I can't help but think if this is related to the "," or ";" as separator. I prefer to use the chart tools - layout- drop down box, anyway.

  3. Mike W says:

    Got to be F11 for instant charting. Highlight your data , hit F11 and voila! ?

  4. Jon Peltier says:

    Ctrl+1 is the most important chart shortcut. In fact, it works for any Excel object: whatever is selected, Ctrl+1 opens the task pane or dialog to format that object.

    Somewhere along the line, maybe when Excel 2016 came out, the arrow keys stopped working to cycle through the elements of a chart. But what works is holding Ctrl while clicking the arrow keys. I haven't gotten used to the Tab and other keys, but as long as Ctrl+Arrow works, I'm good.

    And F4 used to be so helpful when formatting a lot of charts. But since Excel 2007 came out, it has been mostly useless. It used to remember a whole set of changes at once, so I get that the newer modeless dialogs make that impractical. But now it only seems to work with formatting of lines and borders, and maybe fills. I find myself writing a lot of VBA one-liners in the Immediate Window to handle these tedious formatting tasks.

  5. Shelia Hollis says:

    after clicking on a chart, is there a shortcut key to copy it?

  6. Thank you for the Alt E S T - tip. This is more than a time saver. Because of dynamic charts or de-activated external references to data when you make the charts, you often have empty charts that are otherwise impossible to format. So this shortcut helps adressing that. I will work with it more and see if there remain some obstacles.
