I have a static date and military time in B6 (5/10/07 18:00) I have to write various formulas to reflect 1 month (whatever calendar month it ends up in, so not necessarily 30 days) minus 7 days and then the same formula plus 7 days. How is this written?

I'm trying to count the total days between to dates but minus the fed holidays. I have a list of holidays I can ref. I like how the NETWORKDAYS function works but I need to include the weekends.

I recently manage to create a spreadsheet. On the spreadsheet what I am looking to do is once I change the year in cell U1 from 2010 to 2011 to automatically change the days and the date number, and where Sat and Sun preferably to auto-fill in yellow the whole column within the table as you can see in the spreadsheet.if not then just do not display Sat/Sun columns at all..

I need a formula that will allow me to put a date in cell a2, and in cell a3 put the the number of days between 2 dates. Example.. For example (A2) shows 08/06/08, a3 to show the number of days from 08/06/08 to 08/14/2008--(a3 )14 and (a4) to shows the number of days from 08/06/08-10/05/2008 ---(a4) 60 days.

I am trying to calculate dates that will happen 16 days from date specified in column A (A23:A200), based off a certain entry in Column B (B23:B200), which is named in cell P5. I can get the date by doing the specified date + 16, e.g. =IF($B$23:$B$200=$P$5,$A23+16,"")

The trouble I am running into is not having the date populate until it has reached 16 days from the dates in column A, show blank if possible until 16 days from date in column A. The dates in column A will always be previous to todays date.

my spreadsheet is setup with two dates: A date for when someone joins our group A date for when they are released/leave

I want to be able to see exactly how many years/months/days transpired between these two dates. I have tried lots of different formulas with no success.

I have a spreadsheet where I have an intial date of issue of a warrant. Once this warrant has been executed, then a further column is populated with the date. The data I need to work out (Preferably without using macros if possible) is, if there is no execution date the length of time from issue to todays date, but if there is an execution date then length of time from issue to execution. I can do either on their own, but i would like to have only one column showing this info and if possible to update each time the sheet is opened

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 wanted to determine the number of days between two dates. Specifically, if the initial date is in one month, and the second is in a different month and an output would result a number of days in each month until the final date. BUT I have a large amount of data to do this for in a list view, way to put a formula in excel and just drag down the entire list to get the required information. see below for an example.

The result I'm looking for is the separate the months and only show the relevant months between the two dates in one cell or the adjacent. Something similar to the table outlined below.

Assuming the first date is in A1, and the second date is in B1, in standard dd/mm/yyyy form, my current formula is =B1-A1-1.The '-1' is due to the fact that if a patient stays for 10 days, they will only spend 9 nights in the hospital. (Bed Nights).The problem is, the formula is stretched in the total column from, say C1 to C50. Each one of these has, or will have, a number of days in it.However, due to having th '-1' in the formula, empty rows that are yet to have a patients details inputted have a -1 where I need a 0. The only reason I need to change this is because I need a running total of the bed nights of all the patients.I think the formula I'm after is something along the lines of; 'If cell B2 is empty, input 0. If B2 has a date, use formula 'B2-A2'

I attached an excel file for an example. Basically I am calculating on time shipping, but I want don't want Saturday and Sunday to coun't against us.I need G5 to equal 3 days. Right now when I subtract E2 from F2 I get 5 days. But we only work M-F, and Saturday and Sunday shouldn't count against us. How would I subract the days automattically, so it takes out Saturday and Sunday?

I now need to add in the variable of holidays and other days off. This is where I am loss. I do have a list of the weekdays that we did have class and a list of when we didn't

I have a spread sheet that is used to show the dates for the days in the week that my students are in class. I want it to be able to take the date from a cell that has the class start date and then show what the date will be for day 1, day 2, day 3, etc... I am not a beginner with excel but i can't figure out how to get it to skip calendar weekends.

I want to pick a range of dates and find the number of days without sales between those dates. So, a formula that will look to a start date in A1 and an end date in B2, and then count the number of days that did not have sales between. Index/Match/Countif/Dateif I can't seem to make anything work.

I was wondering if anyone knows how I could enter a date in one cell, then another date in a second cell and in a third cell have it have it so it minuses the first date from the second and calculates the difference outputted in number of days.

Today I am having a very annoying problem that really has me stumped – I need to work out the lag between a Due Date and Delivered Date

But as people sometimes manage to deliver on the Due Date it needs to show a zero (as in they got it in on time) but using the formula below the result is a 1 and I want a zero

Can anyone help me please? I have tried putting assorted -1s in to the formula and it looks like it might work until I copy down and find that if a person delivered one day early the result shows -3 for example!

What I would like to do is insert a formula into column E that would calculate the number of days from when the count is at 50 to when the next count is i.e. for part 6689841 the time between when the count was 50 and when it was at 20, so the difference between 21/01/2008 and 08/08/2008 in the above example. It does not matter what the count number is (it could be any number except 50), I'm only concerned with every time the count is at 50 how long it is until the next count and to show the result in days.

I have a spreadsheet where I record individual staff start time, end times and the length of their break. From this I caculate the hours they worked for the day.

E holds Start, F holds End and G holds Break length. Thus using the following forumula gives me the number of hours and minutes:

I am trying to calculate the number of days that items are were held in inventory as of a given date. See below for some sample data.

'As Of' - the date in question # Holdings - Using sumproduct to find items bought on or after the date AND sold after the date Held Days - ? Total number of days that the six items were sitting in inventory as of the date.

As Of #ItemsHeld Days 5/21/98 6

ItemBoughtSoldTotal Inventory Days 19/3/919/3/961827 21/2/921/2/971827 31/2/921/2/971827 43/2/928/21/951267 55/1/925/1/971826 65/1/925/1/971826

If I had two dates in two separate cells , so E2 is the 01/10/08 and F2 is 06/10/08 and I want to work out that their is a difference of five days what would the sum be? Also is there anyway I could factor into that sum what is pure working days as opposed to weekends?

I am trying to calculate the time elapsed. I have included a caption to show my formula. The problem I have is that some times are showing > 60 minutes instead of increasing the hour. When my day go over the midnight hour I get a negative number.

I need to create a formula that calculates the number of days a person has worked within a quarter, if they have also left the organisation within the same quarter.

For example, I have someone who left on 26/08/08. I need to establish how many working days this person actually worked within the quarter (01/07/08 - 30/09/08). I need to do this for a large number of staff, so would appreciate it if anybody can let me know whether there is a formula that would calculate this.

I have a file that's almost 3000 rows of data I have attached a test file for the purpose of this request. I am trying to figure out the average days overdue per department whose due dates have not already passed.test (1).xlsx

I'm using Excel 2003, and successfully working out start date (T2 in the formula below) plus duration in days (U2) minus any non-working days listed in a seperate worksheet. =WORKDAY(T2,U2,Holidays!C6:C17)

Each 'task' is on a seperate row, and the lead officer is named in Column E. How can I get the work day function to include the non-working days for each officer as well as the global non-working days in the seperate worksheet? I thought about using a vlookup, but that only matches the first non-working day for each officer rather than all of the non-working days.

I'm trying to calculate the length of a work order to develop an average and future proposal estimates.

For example: Job received = A1 In work = B1 Job completed = C1 Total days to complete = D1

I know I can enter in D1 C1-A1 and get the correct result but I want the field to calculate A1-TODAY() until a completion date is entered. This would display the number of days the job has been in work until completed. Once completed use the C1 for calculation.

Sorta like If(C1=">=0" then (A1-Today()) else C1-A1)

I will then use conditional formatting with block colors to indicate whether it is a completed job or in work job.
