Calculate workday exclude weekends

In this part, I introduce the formula to calculate workday between two date times excluding weekends.

1. Select two cells which you will input the start date time and end date time, and right click to select Format Cells form the context menu. See screenshot:
doc net work hours 1

2. In the Format Cells dialog, click Number tab, and select Custom form the Category list, and enter m/d/yyyy h:mm into the Type textbox in right section. See screenshot:
doc net work hours 2

3. Click OK. And enter the start date time and end date time into the two cells separately. See screenshot:
doc net work hours 3

4. In the cell next to these two cells, C13, for instance, enter this formula =NETWORKDAYS(A13,B13)-1-MOD(A13,1)+MOD(B13,1), and press Enter key, and you will get the result with custom format, select the result cell, and click Home tab, and go to the Number Format list to select General to format it as the correct format. See screenshot:

Calculate working hours exclude weekends/holidays

If you want to calculate the net working hours excluding weekends or holidays, you can do as bellow:

Calculate net working hours exclude weekends

1. Select two cells and format them as custom format m/d/yyyy h:mm, and enter the start date time and end date time. See screenshot:
doc net work hours 5

doc net work hours 6

2. And in the next to cell, C2 for instance, enter this formula,
=(NETWORKDAYS(A2,B2)-1)*("17:30"-"8:30")+IF(NETWORKDAYS(B2,B2),MEDIAN(MOD(B2,1),"17:30","8:30"),"17:30")-MEDIAN(NETWORKDAYS(A2,A2)*MOD(A2,1),"17:30","8:30"),
press Enter key, then you get a number string. See screenshot:
doc net work hours 7

3. Right click at the number string, and click Format Cells from context menu, and in Format Cells dialog, select Custom form Category list under Number tab, and enter this [h]:mm into Type textbox. See screenshot:
doc net work hours 8

4. Click OK. Now the net working hours between two dates excluding weekends are counted.
doc net work hours 9

Tip: In the formula, A2 is the start date time, B2 is the end date time, 8:30 and 17:30 are the general start time and end time in each day, you can change them as you need.

Calculate net working hours excluding weekend and holidays

1. As the same as above, select two cells and format them as custom format m/d/yyyy h:mm, and enter the start date time and end date time.
doc net work hours 10

2. Select a blank cell, and enter the holiday date into it, here I have 3 holidays and I type them separately in H1:H3. See screenshot:
doc net work hours 11

3. Select a blank cell which will place the counted result, C2 for instance,
=(NETWORKDAYS.INTL(A2,B2,11,H$1:H$3)-1)*("17:30"-"8:30")+IF(NETWORKDAYS.INTL(B2,B2,11,H$1:H$3),MEDIAN(MOD(B2,1),"8:30","17:30"),"17:30")-MEDIAN(NETWORKDAYS.INTL(A2,A2,11,H$1:H$3)*MOD(A2,1),"8:30","17:30"),
and press Enter key, you will get a number string, and format it as custom format [h]:mm. See screenshot:
doc net work hours 12

Tip: In the formula, A2 is the start date time, B2 is the end date time, 8:30 and 17:30 are the general start time and end time in each day, H1:H3 is the holiday cells, you can change them as you need.

can anyone help, i want to extract resolution time excluding night hours (e.g., 6PM to 6AM or 05PM to 8AM) including holidays (i.e., this industry works 24*7 hence does not want to exclude holidays/weekends).

Whenever I do both calculations, my "work hours excluding weekends and holidays" comes out a lot higher than my "work hours excluding weekends" calculation. Anyone know why this might be?

Start date: 1/9/2020 9:00
End date: 28/5/2021 17:00
*Work hours ex weekends:* 1552:00
Formula:

=(NETWORKDAYS(A4,B4)-1)*("17:00"-"9:00")+IF(NETWORKDAYS(B4,B4),MEDIAN(MOD(B4,1),"17:00","9:00"),"17:00")-MEDIAN(NETWORKDAYS(A4,A4)*MOD(A4,1),"17:00","9:00")

Start date: 1/9/2020 9:00
End date: 28/5/2021 17:00
*Work hours ex weekends and holidays:* 1808:00

Holidays:

25/12/2020
28/12/2020
01/01/2021
02/04/2021
05/04/2021
03/05/2021
31/05/2021

Formula:

=(NETWORKDAYS.INTL(A7,B7,11,B$13:B$19)-1)*("17:00"-"9:00")+IF(NETWORKDAYS.INTL(B7,B7,11,B$13:B$19),MEDIAN(MOD(B7,1),"9:00","17:00"),"17:00")-MEDIAN(NETWORKDAYS.INTL(A7,A7,11,B$13:B$19)*MOD(A7,1),"9:00","17:00")

Thoughts?

PLEASE NOTE that the work day and time formula does NOT WORK if the time of the start value (i.e. 11am) is greater than the time in the second value (i.e. 9am). It will give a negative value which will deduct these hours from the work time. To capture that properly, you need to add another condition to the formula. IF(IF(NETWORKDAYS.INTL(B2,B2,11,H$1:H$3),MEDIAN(MOD(B2,1),"8:30","17:30"),"17:30")-MEDIAN(NETWORKDAYS.INTL(A2,A2,11,H$1:H$3)*MOD(A2,1),"8:30","17:30") <0, TIME("17:30"-"8:30",0,0)+(IF(NETWORKDAYS.INTL(B2,B2,11,H$1:H$3),MEDIAN(MOD(B2,1),"8:30","17:30"),"17:30")-MEDIAN(NETWORKDAYS.INTL(A2,A2,11,H$1:H$3)*MOD(A2,1),"8:30","17:30"))),IF(NETWORKDAYS.INTL(B2,B2,11,H$1:H$3),MEDIAN(MOD(B2,1),"8:30","17:30"),"17:30")-(MEDIAN(NETWORKDAYS.INTL(A2,A2,11,H$1:H$3)*MOD(A2,1),"8:30","17:30"))))

I have edited your formula for work hours being 8am to 8pm. In my example, A2 is the start date time, B2 is the end date time, 8:00 and 20:00 are the start and end times each day, H$1:H$8 is the holiday cells.

When the date range does not include a weekend, the formula works perfectly, but when the date range includes a weekend day, the result is always 12:00 greater than it should be

The formula I'm using is =(NETWORKDAYS.INTL(A2,B2,11,H$1:H$8)-1)*("20:00"-"8:00")+IF(NETWORKDAYS.INTL(B2,B2,11,H$1:H$8),MEDIAN(MOD(B2,1),"8:00","20:00"),"20:00")-MEDIAN(NETWORKDAYS.INTL(A2,A2,11,H$1:H$8)*MOD(A2,1),"8:00","20:00")

Here are 2 examples (there aren't any holidays (H$1:H$8) in these date ranges)
Example 1
Start - 2/6/2019 8:46
End - 2/11/2019 8:40
Value Using Formula - 47:54:00
Correct Value - 35:54:00
Difference - 12:00
note date range has weekend date in it

Example 2
Start - 2/6/2019 19:26
End - 2/8/2019 16:15
Value Using Formula - 20:49
Correct Value - 20:49
Difference - 00:00
note date range has no weekend dates in it

Thanks for any help you can give!

=(NETWORKDAYS.INTL(A2,B2,11,H$1:H$3)-1)*("17:30"-"8:30")+IF(NETWORKDAYS.INTL(B2,B2,11,H$1:H$3),MEDIAN(MOD(B2,1),"8:30","17:30"),"17:30")-MEDIAN(NETWORKDAYS.INTL(A2,A2,11,H$1:H$3)*MOD(A2,1),"8:30","17:30"),

Hello

I used your formula "=(NETWORKDAYS(A2,B2)-1)*("17:30"-"8:30")+IF(NETWORKDAYS(B2,B2),MEDIAN(MOD(B2,1),"17:30","8:30"),"17:30")-MEDIAN(NETWORKDAYS(A2,A2)*MOD(A2,1),"17:30","8:30")" works great

But i get with this data negative Errors even using "1904 date system".

The sample data is: 01.10.2018 15:10 / 03.10.2018 11:15 (date format t.m.jjjj hh:mm)

The error is: data and times that are negative or too large show as #######

Do you have an idea.

Juan

Hi everyone,

There is an error on this formula:

=(NETWORKDAYS.INTL(A2,B2,11,H$1:H$3)-1)*("17:30"-"8:30")+IF(NETWORKDAYS.INTL(B2,B2,11,H$1:H$3),MEDIAN(MOD(B2,1),"8:30","17:30"),"17:30")-MEDIAN(NETWORKDAYS.INTL(A2,A2,11,H$1:H$3)*MOD(A2,1),"8:30","17:30"),

If the end time is greater than the start time, the formula give us the wrong value. We have to pay attention to that.

But the formula was very helpful! Thanks

Morning,

I4 = Date Start MFG (9/14/18 8:00)
J4:M4 = Estimated Hours of Work (28)
N4 = Sum(J4:M4)/8 with the 8 representing the hours of work to calculate the # of days required
O4 = MFG Lead-Time.. this is where I'm having an issue..

What I want the spreadsheet to do is to tell me when the job is going to finish; more specifically, the time. However, I'm not sure how to write the formula so it only counts 7:00-17:00 and excludes 17:00-7:00.

Right now, I have a 3.5 day LT beginning at 9/14/18 8:00 and the output is giving me 09/17/18 20:00. But I can't have a 20:00 because it's outside the standard hours of work. The desired result should be 09/17/18 12:00.

Start Date: 09/14/18 8:00AM - 17:00PM is 1, 9/15/18 8:00AM - 17:00PM is 2, 9/16/18 8:00AM - 17:00PM is 3, 9/17/18 8:00AM - 12:00PM is 3.5.. any ideas?

This formula works to return the net working hours and minutes. How can I convert hours to days, based on an eight hour work day? For example, the result "0 day, 18 hours, 45 minutes" should be "2 days, 2 hours, 45 minutes"

  divide the hours by 8 instead of 24 as working hours is 8hrs for your team. so 18 hrs 45 mins/ 8 hrs= 2 days 2 hrs 45 mins (2 days = 2*8 = 16hrs)

Thanks, in general this formula is working great for me thank you but how do I do it for time periods which exceed a month?

My formula is this:

=(NETWORKDAYS(L22,M22,BankHols17to21)-1)*("18:00"-"8:00")+IF(NETWORKDAYS(M22,M22,BankHols17to21),MEDIAN(MOD(M22,1),"18:00","8:00"),"18:00")-MEDIAN(NETWORKDAYS(L22,L22)*MOD(L22,1),"18:00","8:00")

So these two dates show correctly as 11 working hours:

18/05/2017 08:00 AM 19/05/17 09:00 AM

But this one which is over a year difference between the dates shows ups 17 days 8 hours:

18/05/17 00:00 28/05/18 09:00

Thank you.
