# Formula To Return Average Days Between Two Dates In A Given Month?

Jan 13, 2014

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.

## Days Between Two Dates Separated Into Days Per Month For Multiple Dates - Excel

Feb 13, 2013

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.

## Count Working Days Between 2 Dates, But Return A Zero If The 2 Dates Are The Same Day

Jan 15, 2009

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!

## 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.

## Using COUNTIF To Return The Sum Of Dates That Fall Within A Month/Year Range..

Jan 20, 2010

I want to use a COUNTIF to return the sum of all the dates that fall within a given month/year. For example: E1 Contains the date July-2009

Column A has date entries such as July 3, 2009, July 18, 2009, August 4 2009. In F1 I want to return the sum of all dates that fall within the month of E1.

## Formula To Calculate How Many Days In A Month And Create Column For Each Day

May 18, 2012

Formula which can calculate how many days in a month and create a column for each day. Columns for day 28, 29, 30 or 31 also need the formulas in columns 1 to 27 copied over automatically. [sheet name "LARSheet1 to 1" ]

I'm trying to build "Leave, Attendance Management" system using Excel. I am about 40% there so far.

The basic structure of the workbook is as follows:

12x main monthly "Leave Attendance Record" worksheets (i.emonths April 2012 through to March 2013). [I will refer to these sheets asLARSheet1 to LARSheet12 ].
1 x worksheet which holds "data validation" list andvlook up info. ["FormulaListSheet"]
1 x worksheet acting as a database of staff details andpay numbers. ["StaffdBaseSheet"]
1 x summary page which shows staff reaming leaveallocation. ["SummaryLeaveSheet"]

What I'm having problems with at the moment is as follows:

A formula or a macro which works out how many days are present in a given month [starting date of month located in CELL B10].

Days 1-27 will be already set up on the sheet. Based upon the monthly value I would like a solution which can calculate how many days are in a month and create a column for days 28, 29, 30 or 31 (depending on the month).

I would like it to work like this:

When the user opens a new worksheet, they first entre the month start date in CELL B10. Hopefully this will trigger columns E13:AH22 to update with the relevant week day & date.

I also need the formulas and formatting in cells AH13:AH100 (column for day 27) to copied over automatically.

## Formula For Rolling 12 Month Average?

Mar 16, 2010

See Attached.

The YTD 10 column is fine that will change everytime you update each month. I was wondering if there was a formula I could use for the Rolling 12 month Column.

At the moment it is averging from Mar 09-Feb10 which is correct but when it comes to putting in data for Mar 10, the Rolling 12 month column will obviously not change.

Is there a way of moving the formula along one each time you input data into a new month. So when Mar 10 has been entered the rolling 12 month column will pick up Apr-09-Mar-10 then when Apr 10 has been entered the formula will change again to May-09-APr-10?

As you can see this also laps into a new year, which poses my next problem, ill probably just add more columns on to the end of the table for that though...

I will later apply different calculations to these cells but in short need to get a calculation for the number of days per month first.

(in short spreading the new value out accross the year then multiplying it by the days... i also need to apply a further daily volume cal to it).

## Formula That Will Determine The Number Of Days That Fall In A Specific Month Based On A Date Range

Jul 31, 2009

I'm needing a formula that will determine the number of days that fall in a specific month based on a date range. For example, if I have a date range of 10/15/2009 to 01/13/2009, I need the formula to determine the number of days in each month within the range (October has 15 days in the date range; November has 30, December has 31, and January has 13.) I have a large spreadsheet that would be so much easier to manage with such a formula. Currently, my spreadsheet is setup as follows. I need the forumla automatically fill in the number of days under each month.

## Formula / Calculate Number Of Days Between 2 Dates That Equal A Given Value

Mar 19, 2014

I have two date columns, a start date and end date. Another columns tells me the number of days between these two columns. It may return 45 days which actually straddle 3 different months.

So on the spreadsheet Id have 12 columns for each month of the year. in Apr 14 for each row between the given date range I want it to tell me how many days are actually in April. Id then copy that formula into the May 14 column.

## Date Formula- To Count The Number Of Days Between 2 Dates

Aug 4, 2008

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.

The formula i am using to compare the dates is

## How To Ignore Blank Cells In Formula Counting Days Between Two Dates

Jul 22, 2014

I have the following formula which counts number of days between dates in two adjacent cells excluding holidays

=NETWORKDAYS(U311,V311,\$AA\$4:\$AA\$14)-1

The \$AA\$4:\$AA\$14 refers tote range where the excluded holiday dates are stored.

I have included the -1 at the end as it over counts by one day every time. i.e. if the same date is in both cells it counts 1

However if no date is in both fields it count -1 (minus one)

If a date is just in one field it counts a very high number, example below.

-1

16/07/2014

-29879

20/06/2014
08/07/2014
12

[code].....

is there a better formula to use for this? How do I get the result to show ZERO when both cells are empty? can I get the result to show number of days to present date where there is only a date in first column?

## Formula To Return The AVERAGE By Calendar Quarter

Nov 6, 2005

I'm trying to write a formula to return the AVERAGE by calendar quarter, IF
the quarter has ended.
For instance, IF Jan = 5, Feb = 20, Mar 5, Average would be 10.
But, if Mar was 0 (only meaning no activity) I still need it to calculate.

The formula I started with is -
=IF(A1=0,0,AVERAGE(A1:A3)

This works only if cells A1:A3 have a value greater than 0. How can I write
the formula so that as long as A3 is not blank that it will return the
AVERAGE?
