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)

    I would like to see actual hash-tagged DM tweets go out to the specific information consumers. That would be an interesting way to communicate the key daily data to interested parties.

    A Twitter-like secure application like Yammer might be a good fit with this.

    For example, how about daily tweets to selected user groups (secure) that would display sales, bookings, cash receipts, cash disbursed and a second version that would show the same info for MTD, QTD or YTD figures.

  2. Aires says:

    @Dan, it would be great. I did not taught about implementing it on this dashboard because twitter is blocked to the whole intranet here. However, there's a discussion here about how can we send these tweets to blackberries (probably through e-mail) automatically. (I'd like to see this implemented on a jabber restricted network as well, but here it'll probably not happen)

    The wrap-up versions you mentioned doesn't apply to my particular scenario, but on a sales tweetboard it would be a great tool indeed - choosing who will receive which message according to hashtags. I'll think on something, thanks for the advice. 🙂

    (Ah, btw, I'm Fernando... 🙂 )

    @Dan: That is a fun idea. Instead of tightly integrating twitter functionality with a dashboard, i think it would be cool if we have a "tweet this" button that users can click after selecting a range of cells. We can easily show a dialog with the concatenated output of the selected cells and ask user to edit the text and eventually "send to twitter".

    For eg. you can select the annual sales figure cell and click on "tweet this" button upon which a dialog will show the value. Then you can pre-pend it something like "DM @boss look at our sales this year: "

    @Aires.. thanks once again.

  4. Wow it looks really good. Not sure though how much the tweet facility would help in real world project management, but certainly having a dashboard on a project should be a key deliverable when learning how to manage a project

    The other use of this is during the software development life cycle especially when you have parallel streams of development and testing going on. Using a dashboard is a quick way for everyone on the team to see where the project is at and how it all fits together.

    Hi Chandoo,
    I purchased the project management toolkit but the dashboard shown above with the imbedded scroll bars. Is it included in the project pack??
    Thanks

    The gantt chart section of this dashboard is similar to one I have recently created: http://xlcalibre.com/hr-dashboard-gantt-chart-traffic-light-reportIt has a similar approach with scroll bars, but has a couple of additional features. I've tried to incorporate a traffic light report element, and also allow the timescale to adjusted so that can view it by days, weeks or months.I really like the other tables that you've incorporated, I may well try to replicate them to improve my version!

  7. I am a monitoring and evaluation consultant in international development, and one of the services I offer is to help non-profits and foundations develop performance dashboards.  I often advise them to develop dashboards for ongoing programs, rather than for one-time or pilot projects, because of the time involved.  I am trying to find out from a few people how long it takes you to develop a project management dashboard, and to what extent the indicators vary from one project to the next.
