Calculate Workdays Between Dates
Nov 2, 2006
I am trying to map the total networkdays across the months of the year for a list of contracts with variable start and end dates.
Example of the results I'm after:
Contract StartDate EndDate January February March etc.
Contract1 15 Jan 07 13 Jul 07 13 20 20
Contract2 5 Feb 07 2 Mar 07 0 18 2
I assume that the add-in NETWORKDAYS function is involved (and I'm ordinarily comfortable with using this function with only two dates and my named range of holiday dates), but I can't seem to figure out how to use it in this more complicated way. My own extensive struggles with it have led to ridiculously long and nested formulas that even I didn't understand after a few days away from them. I've searched the posts and seen questions similar to mine, but not close enough to give me a solution.

I need a way to calculate the number of workdays, Saturdays and Sundays in a month.
In my model, the client can choose to work on Saturdays and/or Sundays.I need someway to show that a given month (e.g. June 2014) has some # of workdays, and some # of Saturdays and some # of Sundays.I can do this on three separate rows.
eg.
Row 1: Month
Row 2: Wordays
Row 3: Saturdays
Row 4: Sundays
Still i need some way of determining that a given month (June 2014) has 22 work days, 4 Saturdays and 5 Sundays,... et cetera

I have the following function:
=IF(G13="",IF(H13>1,1,IF(G13>1,workdays(H13,G13,Holidays))))
The intent is to calculate the completion date against the assigned date as follows:
G13 - Typically the assign date but sometimes can be blank because someone forgets or doesn't bother to insert
For this example, let's say: 12/17/12
H13 - Completion date
For this example, let's say: 12/20/12
I'm expecting a result of '3' for 3 days
The first half of the function is intended to calculate 1 day if G13 is blank or not defined. However, when I have dates in both cells, I'm getting a "false" answer instead of a numerical value that I'm expecting.
In our workplace, we do work weekends & sometimes 7 days a week.

I need to calculate the difference between two work days to understand how many days late we missed a due date. The NETWORKDAYS formula gives me the COUNT of the workdays, but I need the difference.
Example 1:
Expected Due date: 3/3/08
Actual Due date: 3/3/08
NETWORKDAYS for the dates above gives me the value of 1, but for my needs I need the resulting value to be zero.
Example 2:
Expected Due date: 3/3/08
Actual Due date: 3/5/08
NETWORKDAYS for example 2 provides a value of -3 (days late), but in reality it's only -2 (days late)

Get the number of workdays between two dates in a VBA function. I tried simply using the Advanced Toolpak function NETWORKDAYS, but I get the error message "Sub or function not defined". I did reference to atpvbaen.xls in the Tools > References menu, so I don't know why Excel is not recognizing the function.
I used the following function to test it:
Function CalcNetDays(dInitial As Date, dEnd As Date)
CalcNetDays = NetworkDays(dInitial, dEnd)
End Function
Any reason the function is not working?
Also, I need to add the holidays to the function. The holidays are listed on a worksheet column. Do I simply add the range to the function, like below?
CalcNetDays = NetworkDays(dInitial, dEnd, Range("Holidays"))

I can calculate the networkdays between two dates but how do I project a finishing date if I know the starting date, the holidays, and the duration of the task in working days? (Sample sheet attached, working in Excel 2003).

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.

In my excel I want to use a calender date such as 05/21/09 and automatically add or subtract a specific number of days. For example: 10 days before 05/21/09....
I dont want to have to count back 10 days and manually enter it. Is there a way to have excel calculate and give me the date in my spreadsheet? i.e. automatically calculate (05/12/09)-(10 days)= 5/11/09. its not too hard when its 10 days, but when its -97 days, it can be very annoying.

Calculate dates as The Number Of Days, Months Or Years Between Two Dates
The two formulas I tried below show the wrong output when trying to figure the days between 12/8/2011 to 1/2/2012. It should show 0 years, 0 months, 24 days, not 138 days.
I did notice when the day of the month on the start date is before the day of the month of the end date, the formula seems to work. Ref. the second dates on the first example.
Example 1
Start End
12/8/2011 1/2/2012 = 0 years, 0 months, 138 days
Wrong display. should show 0 years, 0 months, 24 days
Start End
12/1/2011 1/2/2012 = 0 years, 1 months, 1 days
Note that when the start date "day", (1), is before the end date "day", (2) the formula seems to work.
First formula used above:
=DATEDIF(B3,C3-(MOD(B3,1)>MOD(C3,1)),"y")&" years, "&DATEDIF(B3,C3-(MOD(B3,1)>MOD(C3,1)),"ym")&" months, "&DATEDIF(B3,C3-(MOD(B3,1)>MOD(C3,1)),"md")&" days"
Example 2
Start End
12/8/2011 1/2/2012 = 0 years, 0 months, 138 days
Should show 0 years, 0 months, 24 days
Second formula tried above:
=DATEDIF(B10,C10,"y") & " years, " & DATEDIF(B10,C10,"ym") & " months, " & DATEDIF(B10,C10,"md") & " days"

I seem to have the worst luck when it comes to getting dates and times to calculate together. My logic just seems to go straight out the window.
What I am trying to do, the end result, is get a Time Worked (duration) that I have spent on a ticket, and a Total Time, the time a ticket was opened, to the time it was closed.
I guess we can try to do this one step at a time.
The first thing that I would like to know is if there is a way to calculate Date/Time in a MM/DD/YYYY, H:MM format?
IE:
Ticket Opened ...................Ticket Closed
5/16/2008 2:54 PM..............5/19/2008 10:47 AM
Total Time in Days / Hours / Minutes
Right now I have the Date and Time split into separate cells, simply because I couldnt figure out a way to subtract the combined date and time.

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

I thought this would be simple but I can't figure it out. I need to subtract the time between two cells. For example:
Cell A1: 6/6/2007 3:00:00 PM
Cell A2: 6/7/2007 2:00:00 PM
Result would be either 0:23 or 23 as in hours.

I have a countif formula that calculates the number of entries between 2 dates. However i now need to also count how many of these match a 3rd value.
So i will need to work out how many "are greater than or equal to B2" "less than or equal to C2" and "equalling D2"
what i have already
=(-COUNT('Current Work'!AE8:AE2000)+COUNTIF('Current Work'!AE8:AE2000,">="&B2)+COUNTIF('Current Work'!AE8:AE2000,"<="&C2))

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

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 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'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 a spreadsheet that lists items in column A with a start date in column B. What I need to do is in in column C list the next review date in increments of 5 days, but I only want the next day to show from the current date, not the inputted start date.
For example:
Column A Column B Column C
Item Start Date Next Review Date
Item A 12-Sept-09 27-Sep-09
Can I get a formula to calculate the increments and only show the next calendar date for the review, and then to change to the next date once the previous date has passed.
Alternatively, I have another sheet in my workbook that calculates the dates, is there some way I can display the next future date in a line of dates?

I'm not too hot with Excel formulas but I'll explain as best I can. I have 3 columns with dates and times
A - 01/08/2008 08:17:08
B - 01/08/2008 12:17:08
C - 01/08/2008 17:00:11
This is what I want to do...
If A > B then Calculate the time difference between A and C
If A <= B then Calculate time difference from B to C
I'd like to get this formula in 1 cell if possible?
