How to Calculate Working Hours Between 2 Dates [Solution]

This post builds on earlier discussion, How many hours did Johnny work? I recommend you to read that post too.

Lets say you have 2 dates (with time) in cells A1 and A2 indicating starting and ending timestamps of an activity. And you want to calculate how many workings hours the task took. Further, lets assume,

  • Start date is in A1 and End date is in A2
  • Work day starts at 9 AM and ends at 6PM
  • and weekends are holidays

Now, if you were to calculate total number of working hours between 2 given dates, the first step would be to understand the problem thru, lets say a diagram like this:

Working hours between 2 dates - how to write a formula

We would write a formula like this:

=(18/24-MOD(A1,1)+MOD(A2,1)-9/24)*24 + (NETWORKDAYS(A1,A2)-2)*9

See the above illustration to understand this formula.

Now, while this formula is not terribly long or ineffective, it does feel complicated.

May be we can solve the problem in a different way?!?

Michael left an interesting answer to my initial question, how many hours did Johnny work?

Pedro took the formula further with his comment.

The approach behind their formulas is simple and truly out of box.

Instead of calculating how many hours are worked, we try to calculate how many hours are not worked and then subtract this from the total working hours. Simple!

See this illustration:

Working hours between 2 dates - a better formula

So the formula becomes:

Total working hours between 2 dates – (hours not worked on starting day + hours not worked on ending day)

=NETWORKDAYS(A1,A2)*9 - (MOD(A1,1)-9/24 + 18/24 -MOD(A2,1))*24

After simplification, the formula becomes,

=NETWORKDAYS(A1,A2)*9 - (MOD(A1,1) -MOD(A2,1))*24 -9

=(NETWORKDAYS(A1,A2)-1)*9 +(MOD(A2,1)-MOD(A1,1))*24

Sixseven also posted an equally elegant formula that uses TIME function instead of MOD()

=(NETWORKDAYS(B3,C3)*9) - ((TIME(HOUR(B3),MINUTE(B3),SECOND(B3))-TIME(9,0,0))*24) - ((TIME(18,0,0)-TIME(HOUR(C3),MINUTE(C3),SECOND(C3)))*24)

If someone asks me what is the most valuable part of this site, I would proudly say, “the comments”. Every day, we get tens of insightful comments from around the world teaching us various important techniques, tricks and ideas.

Case in point: the comments by Michael, Pedro and Sixseven on the “how many hours…” post taught me how to think out of box to solve a tricky problem like this with an elegant, simple formula. Thank you very much Michael, Pedro, Sixseven and each and every one of you who comment. 🙂

Have a great weekend everyone.

PS: This weekend is my mom’s birthday, plus it is a minor festival in India. So I am going to eat sumptuously, party vigorously and relax carelessly. Next week is going to be big with launch of excel school 3.

    Would be considerably easier just to have a table with the variance shown.

  2. Jomili says:

    On Step 3, how do you "Add budget and actual values to the chart again"?

    • Chandoo says:

      There are a few ways to do it.

      Easy:
      1) Copy just the numbers from both columns (Select, CTRL+C)
      2) Select the chart and hit CTRL+V to paste. This adds them to chart.

      Traditional:
      1) Right click on chart and go to "select data..."
      2) From the dialog, click on "Add" button and add one series at a time.

      • Neeraj Agarwal says:

        One more way to accomplish it is just select the columns into chart. Press Ctrl+C and then press Ctrl+V

  3. TheQ47 says:

    Unfortunately, this doesn't seem to work for me in Excel 2010. The "Var 1" and "Var 2" columns cannot combine two fonts to display the symbol and the figure side-by-side.
    Secondly, there is no option to Click on “Value from cells” option when formatting the label options. The only options provided are Series Name, Category Name or Value.

    • Chandoo says:

      @TheQ47... the emoji font also has normal English letters, so if you use that font, then you should be ok. I am assuming your computer doesn't have that font or hasn't been upgraded for emoji support.
      Reg. Excel 2010, you can manually link each label to a cell value. Just select one label at a time (click on labels, wait a second, click on an individual label) and press = and link it to the label var 1 or var 2.

    I am using excel 2010, please explain how to apply Step 12

    Hi Chandoo,

    I just found your website, and really love it. It helps me a lot to be an Excel expert 😉

    Currently I am facing with a problem at step 11:
    Var1 Var2
    D30%
    A5%
    B0%
    B4%
    B7%
    C10%
    C13%
    D27%
    I42%

    Though at mapping table, I used windings, here formula uses calibra. How I can change it? I am able to change only the whole cell. In this case numbers will be Windings too.

    Thanks for your help!

    • Chandoo says:

      Hi Mariann... Welcome to Chandoo.org and thanks for your comment.

      If you wanted to use symbols from wingdings and combine them with % numbers, then you need to setup two labels. One with symbol, in wingdings font and another with value in normal font. Just add the same series again to the chart, make it invisible, add labels. You may need to adjust the alignment / position of label so everything is visible.

  6. […] firs article explains how you can enhance your charts with symbols. You can simply insert any supported symbol into your data and charts. To some extend you can […]

    You're a good person, thank you to share your knowledge with us, I will try to do in my work

  8. Ali says:

    Great visualization of variance. My question is that is this possible in powerbi?

    How would you go about it?

  9. NARUTO says:

    HELLO, WHY CANT I FIND VALUES FOR LABELS IN EXCEL 2013

  10. Amol says:

    Dear chanddo sir,

    What to do if we have dynamic range for Chart. How this will work. can you able to make the same thing works on dynamic range.

  11. Ricardo says:

    Sir Chandoo,

    Good Day!
    First, I'd like to say that I am very grateful for your work and for sharing all these things with us.

    I tried to do this chart but it seems that the symbols don't work with text (abs(var%),"0%") unless we keep the Windings font style.
    The problem is, it converts the text into symbol as well and you wont see the 0% anymore. I'm using Windows 7.

    Sir This is awesome chart, and very easy to made because of your way to explain is very simple , everyone can do. Thank you

    one problem i am facing, I hv made this chart , but when i am inserting data table to chart it is showing two times , how can i resolve this

  14. renuka says:

    in this chart when i am adding new month data for example first i made this chart jan to mar but when i add data for the apr month graphs updated automatically but labels are missing for that new month

    • Chandoo says:

      Hi Renuka,

      Please make sure the formulas for labels are also calculated for extra months. Just drag down the series and set label range to appropriate address.

  15. Justine says:

    So I am playing with the Actual chart here - but amounts are bigger than your - you have 600 as Budget - my budget is 104,000 - is there a way to shorten that I am unaware of

    thank you - I LOVE YOUR SITE

  16. Arvind says:

    Thanks for the tips and tricks on Excel. In the Planned versus Actual chart examples, you use multiple values (ex. multiple Categories in above). How can this be done when we have only 1 set of values? For example if I have only this:
    Planned Actual
    SOW Budget 417480 367551

    How can I create a single bar chart like the one above?

  17. JEREMIAH KOOL says:

    Thank you Chandoo.
    This one is just perfect for my Quarterly Review presentation on Operational Budget against Actual Performance for the Hospital I'm currently working with.

  18. Shawn says:

    Is there a way to make the table of data into a pivot table to be able to add a slicer for the graph due to many different categories and months?

  19. Mihail says:

    Hi, I tried to modify you template with something appropriate for me, and I found a problem. this template was modified by me started with excel 2010, then 2016 and finally 2019. Same thing - somehow appear an error - or didn't show the emoticons for positive percentage or doubled the emoticons for some rows. I suspect to be from excel. if is need it I can sand you my xlsx for study. Please help if you can.

  20. Saidatta Pati says:

    Hi Chandoo,
    Could you please check the Var Formula in Step1. You have mentioned budget-actual and when i did this i got different values but when reversed like actual-budget i got the actual value what you have demonstrated in step1.
    Please share your view.

  21. Dan says:

    This is a great chart (budget vs. actual). However, in trying recreate it, I cannot color in the UP Down bars individually, and they all become formatted with the same color. I'm using Office 365. Look forward to the feedback.

    Thanks.
    Dan

  22. sathik says:

    pls explain in detail step 7

  23. Arun says:

    While in the Excel sheet you have used following formula for Var
    Var = Actual - Budget
    But
    in the note, you have written
    Var = Budget - Actual
