# Calculate Day Difference Between Dates Excluding Certain Days

Feb 2, 2008
I am attempting to get the formula in Column "E" (see attached excel file) to work based off the individual reps 'days off / holidays' (Columns K:P (or more as needed) that they might have. the formula I am using (which works fine) is:

=IF(C2=D2,0, SUMPRODUCT((WEEKDAY(ROW(INDIRECT(C2&":"&D2)),2)={2,3,4,5,6,7})*(COUNTIF($K$2:$S$2,ROW(INDIRECT(C2&":"&D2)))=0)))

My issue comes up when I am coping this formula for say 100+ rows. When I copy the formula to all of the rows, the (COUNTIF($K$2:$S$2) becomes static and does not realize that the row (ie. Row 26 Rep C) has different days off than Rep A. I can manually change the reference for the countif to specify the correct row to their own days but that becomes tedious very quickly. I was wondering if anyone has come across a way to make the countif work based off of that the name in Column B matches the name in Column G then looks 'to the right' and uses the 'days off' that are listed for the corresponding Rep. I have tried a few different ideas but nothing has worked so far.

I wanted to calculate the difference between dates, excluding the weekends. After much thought i used =NETWORKDAYS(A1,B1)+IF(NETWORKDAYS(A1,A1)+ NETWORKDAYS(B1,B1)=2,-SIGN(NETWORKDAYS(A1,B1)),0) that seemed to be working fine. However, I had a problem today with this formula when my start day was saturday (24/05/08) and the last day was monday (26/05/08). What i want is that when i take the difference between these two days, i should get zero as answer as we are not including the weekends in calculation so the start date should ideally be the first weekday which is Monday. However, the formula is giving me 1 as an answer.

This formula works fine if i select 27/05/08 as last date in which case i get 2 as an answer which is right. In gist, what i am looking for is a formula which will give me the difference between two dates and exclude the weekends from the calculation. The last date can't be a weekend, but the start date can. Hence, whenever the start date is a weekend, the formula should take monday as a start day.

how to find the number of days between 2 Dates excluding weekends and holidays using vba. I m using excel 2003. All I know is to figure out todays date using the keyword 'Date'.

Also, this is my second post and I have tried to comply with the rules regarding the title, but if it is still inappropriate and does not meet 'stating the problem' criteria,

I want to calculate the end date of my German courses. This is how it works:

A course consists of 60 LU*. The course can occur i. e. three times a week: Monday, Wednesday and Friday. In each day the course lasts 2 LU, which means 6 LU each week. There is no course on Tuesday, Thursday, Saturday, Sunday and on holidays. Therefore this type of course that begins on 18-Nov-2013 will end on 03-Feb-2014.

Another course which occurs Tuesday, Thursday and Saturday, and respectively has 2 LU on Tuesday, 2 LU on Thursday and 3 LU on Saturday and starts on 03-Dec-2013 will end on 06-Feb-2014.

Therefore I want to create a worksheet where I set the start date, choose the days and respectively the LU amount on those days. The end date shall be calculated according to these criteria.

The workday function on excel cannot do this and I do not have any programming skills to work with VBA.

Legend:

*LU = lesson units; 1 LU is 45 minutes

Holidays:

28-Nov-13

29-Nov-13

08-Dec-13

09-Dec-13

25-Dec-13

31-Dec-13

01-Jan-14

[Code] ...........

How should I calculate working hours between two dates? Say if start at 9/25/2009 7:26:13 PM and finish at 10/20/2009 9:46:13 AM, the function should return 245:20:00 because the working hours are from 8am to 11 PM (8 - 23), and there are weekends between the dates. Preferably the function should work like the NETWORKDAYS() function, but it should also include the time, not just the dates.

Cell A1 contains 02/29/2012

Cell B1 contains 12/01/2006

I am looking for a formula that will return the number of months (periods) between two dates, ignoring days and years. Using the above dates, which cannot be changed, the result needs to be 63. The formulas I have tried keep returning 64 because my later date is at the end of a period, and my earlier date is at the beginning.

I need to create a spreadsheet that will calculate the difference between two dates and show the result in days. The complicated part is that weekends (Sat and Sun) need to be ignored and any time after 4:30 pm needs to be treated as the next business day. I have been trying to look at similar questions in forum and use the WORKDAYS function with little success.

Example:

A1- 14/08/09 4:40 p.m.

B1- 17/08/09 9:10 a.m.

I need the answer (B1-A1) to show up as 0. But if the time in A1 was changed to 4:20 p.m. than the answer should be 1 day.

I am creating a problem report spreadsheet for work. In col C I have a date/time that the problem started, eg, 23-Jun-2006 15:20 and in col D I have a date/time for when the problem was resolved, eg, 26-Jun-2006 15:40. I need to calculate the amount of hours that we were not available for use (due to the problem). This is based on a list of available hours. Eg, on Mondays we are available 19.5 hrs, T-F 22.5 hrs, Sa 14.5 hrs, and Sun 0 hrs.

If I do a straight subtraction, it uses 24 hrs for each day - not taking into account our available hrs. If I do NETWORKDAYS it automatically doesn't consider Sat or Sun - and i need it to - and it does have a DayEnd and DayStart but it assumes they are constants. I found the day corresponding to the date and thought I could determine the series of days between it, e.g., if the start day was Friday & the end day Monday, the series in between is Sat & Sun. Then I could do a lookup on all 4 days in a table & add them all together. But I can't figure out how to do this!

I need to calculate the amount of time between two dates, and show it in the number of hours and minutes. My dates are formatted to show the time in Zulu time. So 1406 = 2:06PM.

Here is what I have:

A1 = 6/4/08 1406Z

B1 = 6/5/08 0402Z

For this example, the formula should return a result of 13 hours and 58 minutes. With the result, there is no need to desingate Zulu time with a 'Z'. But I need the result in a format that will allow me to calculate an average for all my data.

This is more of a query on date dif

I was trying to calculate the difference between two dates on excel

I had a look through the search message board and searched the web generally where I came across the datedif function

I had found that in order to get the number of years it was

=datedif(startdate,enddate,"Y")

for months same formula"YM" and for days use "MD" in place of "Y" in the original formula

My question is when using datedif to calculate the number of days between two days it initialy gave me the right answer

Number of days between 01/08/2008 - 22/08/2008 - Answer 21 days

Using date dif gave me 21 days but when i did

01/08/2008 - 01/09/2008 - this gave me 0

Am I entering the formula wrong or does datedif simply not pick the difference if the days havent changed even though the month has ?

I then found i could simply minus one from the other , which then had me asking what is the point of date dif

is anyone aware of a formula/macro that can calculate (in days, hours and minutes) how much time has elapsed between two date and time stamps?

For example [30/07/2008 00:30] and [01/08/2008 01:45], so in days hours and minutes it would look somewhat like this: 02:01:15

Example.xlsx

how to calculate the difference in value of an item between two dates on a pivot table. I have one table that feeds the Pivot Table and it has three fields:

Data as of Date

Item

Value

So each day, the Data as of Date is updated to the current day and the items are the same but the values are different. I need to calculate the difference in value between the most recent date and x days ago. I cannot figure out how to do this via Pivot Table.

I'm just trying to calculate the difference between dates in two columns and applying conditional formatting based on if it is a positive or negative number. But when there is a null value in either of the date columns I don't want anything returned.

So far I'm either getting a 0 or a FALSE.

Column A = Date 1 Column B = Date 2 Column C = Formula

=IF(NOT(ISBLANK(B2)), B2-A2, )

I have two Rows of data. Each row contains a unique Name column and separate columns for Date, Hour and Minute. I would like to calculate the Time difference in Days, Hours and Minutes between the two Dates. I’m not sure if the way I’ve set it up is the most practical. I’ll attach the spreadsheet to better explain.

I have a pivot table and I created a formula that says:

=jobCompletedDate-jobCreatedDate

and so for example, I have

3/31/2014 7:21AM - 3/31/2014 6:33AM

and that difference is giving me: .03367

I'm not sure what this value represents......the difference in dates, converted to ??

I need to calculate the date difference between two dates and get the result in the number of years and proportion of months ie;

20/09/99 to 01/02/02 is 2.33333333 years. I can use the DATEDIF function to get 2 years 4 months as the result but for the calc I'm doing I need it in the format of 2.33333333. Thinking I just need to tweak the DATEDIF a bit but just can't work it out!

I have a spreadsheet with Received Date/Time in C2 and Resolved Date/Tim in D2, Work Start Time in E2, Work End Time in F2. C2 and D2 are in dd/mm/yyyy hh:mm AM/PM format:04/03/2008 10:27 AM06/03/2008 1:06 PM9:00:00 AM5:00:00 PM

I need to be able to calculate the resolution time of each request in hours/mins excluding weekends and public holidays. I've tried using the NETWORKDAYS function but it doesn't seem to pick up multiple days between the Received and Resolved dates/times. I have put the Public Holidays in my spreadsheet ( attached) in AA2-AG2.

I'm trying to make a formula to calculate the difference in a date between two dates. For exaple, in my business we have a due day for something. So the due date could be Feb 10, we need to know if it was done on time, late, or early. So I've gotten it to display late by doing this: =IF(B2>A2, "Late", (A2-B2)) But then I can't figure out how to incorporate this: =IF(B2=A2, "On Time") or =IF(B2<A2, "Early").

I would like to displaly this all in one cell. So if the due date is Feb 10 and it's turned in Feb 8 it's early, turned in Feb 10 it says on time, turned in Feb 11 it's late. I also tried this but it didn't work: =OR(IF(B2>A2,"Late")*IF(B2=A2,"On Time")*IF(B2<A2,"Early"))

I need also to calculate difference between dates(dd-mm-aaaa hh:mm) in workhours ( hh:mm):

The work period is 9-18 with lunch interval 13-14 The startdate and end date could be out of the work hours and i can't include the extra hours. I can have several days (workdays) at the difference, but i should maintain the format hh:mm.

Ex1:

Startdate 05-03-2013 18:34 ( date to calculation should be 05-03-2013 18:00)

end date 06-03-2013 10:30

Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 )

will be equal to:

Startdate 06-03-2013 8:34 ( date to calculation sould be 06-03-2013 9:00 )

end date 06-03-2013 10:30

Time Difference 1:30 ( from 9 to 10:30 of 06-03-2013 )

Ex2:

Startdate 06-03-2013 12:01

End date 06-03-2013 14:28

Time Difference 01:29

I am trying to calculate the number of days between two dates where the arrival date is in b5 and the departure date is in c5 for each month. I have been using the following formula =IF($C5="","",MAX(0,MIN(L$1,$C5)-MAX(K$1,$B5))) but when the stay is a full year it is giving me 365 in a single column. I think maybe I need to add in the number of days in the month but not sure how to do it.

I have a start date formatted as dd/mm/yyyy in cell A5

I have an end date formatted as dd/mm/yyyy in cell E5

In cell F5 I would like the result of the number of days between E5-A5 (Excluding weekends)

In cell G5 I would like the total number of days in the range F5:F25

In cell H5 I would like the total number of working days from A5 to Today

I am using the following formula to get the result in F5 etc

=SUM(INT((WEEKDAY(A5-{2,3,4,5,6})+E5-A5)/7))

I have copied this down and in the blank cells I get #NUM!

In cell F? were there is no date entered in cell E? I get a minus number (which I can hide using conditional formatting), but the minus number obviously has an affect on the result in G5, as cell G5 gives me #NUM! instead of the result for the current numbers in row F
