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.

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 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?

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've managed to sort the first half of this issue, in that I can calculate the number of days within a given month which fall inside specified to and from date parameters..

This examines a date value (A13 in this case) and assess whether any days within that month are between the two date parameters specified in H9 and I9.

H9 = 01/01/2011 I9 = 15/05/2011 Jan-11 31

[Code]....

What I need to do now is specify a second set of date parameters in H10 and I10 and add those into the assessment. The dates will NOT overlap.

So, for example, if I were to set H10 as 01/07/2011 and I10 as 15/07/2011, the results would appear as below

I really can't wrap my head around the idea of calculating overlap (in network days) between six date ranges and was wondering if any of you would have a solution to this problem.

I am having difficulty calculating the number of total overlapping days between several date ranges for each item in another sheet which has unique items

I am using Excel 2003 and my data looks like this:

Sheet-1 Sheet-2 Item - Sent Out (A) - Received (B) Unique Item Number of days excluding overlap days 1234 01/06/2010 - 30/06/2010 1234 - 4321 02/06/2010 - 16/06/2010 4321 - 1234 09/06/2010 - 10/06/2010 4321 21/06/2010 - 25/06/2010 1234 23/06/2010 - 25/06/2010 4321 23/06/2010 - 29/06/2010

I have used the below formula found from the earlier post but need to add a condition calculating the days for each item.

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.

I'm attempting to write a formula that will allow me to determine the number of days between two dates but to leave the cell with a zero in it if either of the first two date cells are blank or have N/A in them. Here's what I have so far:

=IF(AND(K5="N/A",L5="N/A"),0,L5-K5)

This will give me a zero in the cell if both date cells are blank or will give me the days between if not. How do I get it to also put a zero in the cell if only one of the date cells is blank?

I have been using a formula to count the number of days between 2 dates and if the date was older than 12 months it would work fine.

The data that i was using has been changed and they have decided to change the format of the dates and dropped the year reference no all i have to work with is dates like 27-07 this represents 27th July i can format this date to work fine unless the date falls before 1 jan this year all i get is lots of numbers and it stuffs up the whole calculation.

I am putting together a simple table to display current week's data vs previous weeks. The current week's data is drawn from a status chart which changes frequently. The constant change is fine for 'Current' as I only want the current data displayed.

The problem I am having is calculating the number of late jobs that existed during the previous week.

The status log has a due date which is compared to the current date to determine 'on time' status for the current week. Due dates are reissued regularly so I can't use

=COUNTIF(RANGE,WEEKNUM(NOW()-1)) to return data about last week from my status chart.

I have available a 'Movement Log' (in the workbook but a separate worksheet) which tracks the changes in the due date field, but I'm not sure how to integrate that data to calculate the # of jobs that were running late from the last week.

My thought is that I need to perform a count of the # of late based on a comparison of 'due date' to 'date of the last day of last week' with a way to insert the "old due date" from the movement log to replace what is shown in the status log if necessary.

I have spent too many hours Googling and trial with mostly error in attempting this. I formatted the very first cell A1 for today's date =TODAY(); this is also dirrectly above the column with all the dates in it. I just want an entire row's contents to turn red if it is 15 days old or older. This =$A1<TODAY()-15 somewhat works, but it only turns the date cell red, not the whole row. It also makes blank cells turns red, which I would like to remain blank (another formula is needed I imagine).

Within a user entered range of two dates, I would like to identify the individual calendar date(s) and count the number of Mondays which fall within the specified date range.I will eventually be using the same "Monday" code to find the same data for every day of the week within the dates ranges, but I figured I'd start with Mondays and build from there.

For Example: Date range 1/1/2013 - 1/15/2013 (date ranges could potentially encompass a full business quarter) Within the range, list each of the dates as dates. (used for comparative counting purposes elsewhere in the document)Count the number of Mons, Tues, Weds, Thurs, Fris, and Sats within the date range.Based on the example date ranges above; Mons = 2, Tues through Sats = 3 each.

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.

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.

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?

There are dates in column C and I need to count how many days are coming due within 90 days of each date based on the today() function but do not exceed the 90 days.

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.
