Average Number Of Days Between Array Of Dates?
May 6, 2014
I'm working on building a workbook to track sales progress, and I'd like to perform an analysis on some of the data with regards to sales efficiency.
To simplify:
Column A = Initial Contact Date (mm/dd/yyyy)
Column B = Close Date (mm/dd/yyyy)
As an example, I would like to calculate the average number of days between the Initial Contact Date and the Close Date to calculate the average number of days in the prospecting cycle. Basically, the formula should function as AVERAGE((B1-A1)+(B2-A2)+(B3-A3)...) and so on for the entire column.
I know one solution would be to insert a new column that performs the subtraction between the two dates, and then I could AVERAGE this new column. However, I want to perform similar calculations to analyze the time period between other key milestones in the prospecting cycle - rather than have a lot of extra columns in my sheet, I was wondering if there's some type of array formula that will calculate what I need.

My sheet looks like this - example:
ID Dates CombinedAverageDaysFromID
0001 2012-02-01 ?
0001 2013-08-10

I need to calculate the average days between the dates for each ID? How do I do this?

I have a workbook with two sheets. The first has a list of job positions open, columns designated to stages in the employment process and in these columns, my staff enter the dates that they completed a particular stage.
"Position | Date Opened | Stage 1 | Stage 2 | Stage 3 | Stage 4"
Pos 1 | 01/01/2014 |02/01/14|03/01/14|07/01/14|09/01/14
This has a great number of entries and they are increasing and decreasing every day depening on the amount of jobs available.
On the second sheet, I am trying to set up a table which shows the average working days it is taking to complete each stage, divided into the months in which the job position was opened (i.e. for positions opened in january, the average completion working days for stage 1 was X amount of days etc...)
I have tried using =IF(AND(Logical, Logical),TRUE,FALSE) but this doesn't return any info as the logicals will always be false. I tried the OR function, but that requires only one of the criteria to be true to return a value. What I need is for the formula to return a number of days between two dates, ONLY if the opened date falls in one month.

Here is my set up:
A2 to BF2 is a range of dates
A3 to BF3 are sales. Days without sales are 0.00
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 would like to find the average number of days events take from start to finish.
My data is in 3 columns:
EventName StartDate EndDate
I have a ton of EventNames, each of which have a StartDate. But I want to calculate the average days to complete only for those EventNames that have EndDates.
So, if a cell in the column EndDate is greater than zero, then take that cell, subtract it from the corresponding cell in the StartDate column; Add all of them together and divide by the count of those rows in the EndDate column that have a value.
How do I put this in excel terms? ....

I need a formula to determine the average number of days between sales transactions for each item in inventory. There are several hundred different item numbers with thousands of transactions.
I have attached an example of what I'm looking for. I've toyed around with Average and If functions but can't seem to get it right.

How to create a spreadsheet with what I think will be a very simple formula?
If date in B2 - date in A2 is 1 or less days, put a 1 in cell C2.
If date in B2 - date in A2 is 7 or less days but more than 1, put a 2 in cell C2.
If date in B2 - date in A2 is 30 or less days but more than 7, put a 3 in cell C2.
If date in B2 - date in A2 is 90 or less days but more than 30, put a 4 in cell C2.
If date in B2 - date in A2 is 91 days or more, put a 5 in cell C2.
OR
Another, maybe simpler, way of saying it is:
If date in B2 - date in A2 is 1 or less days, put a 1 in cell C2.
If date in B2 - date in A2 is 2-7 days, put a 2 in cell C2.
If date in B2 - date in A2 is 8-30 days, put a 3 in cell C2.
If date in B2 - date in A2 is 31-90 days, put a 4 in cell C2.
If date in B2 - date in A2 is 91 days or more, put a 5 in cell C2.

I have a start date (say 01/04/07) and I need to add a number of days to it to get the start of the next financial period. Unfortunately, I need to ignore a small list of dates (bank holidays, etc).

I am trying to set up a function to derive a number of days between 2 dates.
Within the table I have an on hire date, and off hire date, and an optional suspend hire date range in 2 other columns - ie. there are 4 columns with dates in.
On hire is in column B; offhire in C; suspend hire in G and recommence hire in H. The optional suspend hire date range will always fall within the main hire date range.
Column I calculates the number of days for the suspend hire period.
My key cut off date is in cell C4.
There are 3 different scenarios I need the function to cover.
1 - if the cut-off date (in C4) is later than recommence hire, calculate the number of days from hire start to cut-off date, less suspend hire period days.
2 - if the cut-off date (in C4) falls within the suspend hire period, calculate the number of days from the hire start to the begining of the suspend hire period.
3 - if the cut-off date (in C4) falls before the suspend hire period, calculate the number of days from the hire start to the cut-off date.
This is the fuction I have written:-
=IF($C$4>H10*($C$4-B10-I10),
IF(AND($C$4>G10,$C$4

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 currently working on a file that has employee holidays/sickness etc. What I want to do is be able to see is a DATE FROM and DATE TO and next to it the total amount of working days between and including those dates. On top of the since employee's sometimes like to take half days I need it so that it can determine half days as well.
So for example I have an employee going to be off work from 29/10/2007 until 09/11/2007 12pm which is 10.5 days in total, but that includes weekends when I don't want it to.
Also it comes out as 11 days at the moment because I can't figure out how to get it to determine is it is half a day.
What formula should I use or if someone could create an example that would be really usefull :D

Need a formula (E1) to determine the number of days that have passed between two given dates (C1 & D1) ONLY when the Status of a given report (B1) is "Late"
B1 = Status (Pending; On Hold; Late; Completed) (i.e "LATE")
C1 = Status Date (i.e. 28 Mar 14)
D1 = Deadline (date) (i.e. 25 Mar 14)
E1 = Total Days Late (= ?)

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

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 looking for the formula to calculate the number of winter days between two dates.
Say, that I'm having:
- Winter season start date (say Dec 1st)
- Winter season end date (say, March 1st)
=> All the days which are between these two are considered winter days for any given year.
- Two different dates defining the beginning and the end of my PERIOD. The total length of the period may be more than one year.
HOW do I calculate total number of winter days for the PERIOD?

I need to count the actual number of days between 2 dates but excluding Sunday...
For example,
Start Date-----End Date-------# of Days
01/Jan/14-----23/Jan/14-------20 days (excluding Sunday)
In some cases, Holiday also to be removed i.e. 01-Jan-2014 is holiday, then the # of days should be 19 days.
If I use Networkdays formula, then system results excluding both Saturday and Sunday. But I want to remove only Sunday.

I'm new here. I've searched these forums in the past for help, but never had to post, i've always been able to find something by searching. However, this time I couldn't find anything that addressed my specific need so I figured it'd be worth a shot.
Alright, I have two sets of dates, and i'm trying to set up a formular that calculates the numbers of days from the first date range that overlap/fall within the second date range.
For example:
In A3 type "1/1/2006"
In B3 type "1/1/2007"
In C1 type "6/30/2005"
In C2 type "6/30/2006"
Now, in C3 i'd like to insert a forumla that tells me how many days in the date range of 1/1/2006-1/1/2007 fall in the date range of 6/30/2005-6/30/2006. Basically for this is should be half the year, however many days that is.
Is this possible with a formula?

Worksheet '1234' has 10 invoices, 6 of which are more than 30 days old (invoice dates are in column B). Worksheet 'Summary' needs to display the total number of invoices and the number older than 30 days.
