# Formula To Count Number Of Days In Date Range - Split Per Month

Jan 23, 2012
I have a large spreadsheet which holds lots of data with date ranges that i need to performs different actions to. Any way to identify the number of days, per calender month, that falls in a date range.

sample data...

Start Date

End Date

Old Value

New Value

08/03/2010

18/06/2010

16758.2

16758.1

[Code] .......

I need to break down the total number of days per month

Jan

Feb

Mar

Apr

May

Jun

Jul

Aug

Sep

Oct

Nov

Dec

24

30

31

18

[Code] ......

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).

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.

Stard Date End Date Oct-09 Nov-09 Jan-10 Feb-10

10/15/2009 01/13/2009

I'm using Excel 2007.

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

=DATEDIF(N31,$D$1,"d")

B1-End Date Mar/31/2014

C1-No Of Days 22

D1-Days between two dates 21

E1 To E10-Holidays

2-Count number of days between two dates where working days are (Sat to Thursday). So required to exclude (Friday + Holidays)

My problem is , I have a date range 21-Feb-2013 till 07-Mar-2013 (Col C2, Col D2 respectively) which is holiday list for a person.

I am trying to pull out the number of working days for that person in the month of Feb which should exclude weekends.

To get the total no. of working days for the month of Feb, I have used the below formula.

=NETWORKDAYS(DATE(YEAR(C2),MONTH(C2),1),EOMONTH(C2,0))

This gives me a value of 20 which is correct.

Now I need to find no. of days which fall under the month of FEB from the date range 21-Feb-2013 till 07-Mar-2013 (Col C2, Col D2) which are working days. so that I can subtract that from no. of working days for that month (FEB) to get the no. of working days which the person has actually worked.

I have three companies in column A, In Column B I have a date of when an item was sent to them, in Column C I have the amount of days this item has been out with that company. Is there a formula that will count the number of days an item has been out with one of the companies per month, and find an average if more than 1 item has been sent per month. Two items have been sent to company A in Sep 09, one item has been there 10 days the other 20 days, the answer I would be looking for is 15.

I have two columns of dates, leave start and end dates (when people start leave i.e. annual leave). Would need to introduce column(s) to calculate how many days fell within the month including the end date and excludes weekends.

For example, if the staff on leave from 31st March to 6 April, i need to show that the number of leave taken as 1 day in March and 4 days in April.

I have checked searching the forums for this but nothing that really matches what I am looking for. I am trying to, from a date, deduce how many days there are in that month. I have tried a solution where I look at EOMONTH adding and subtracting but this is quite cumbersome. Is there some code out there where someone has solved this?

At the end of each month, my agency collects data about clients served in our programs. One of the many pieces of information they want is the number of "bed days" a client was residing within our programs for the given month.

For example:

Jon Doe entered the program on 7/16/13 and discharged on 8/15/13. I would like to know how to calculate the number of days in July that Mr. Doe was residing in the program. (The date of discharge is not included.)

I recently took over the responsibility of completing reports such as this one at my office. The previous person who completed the monthly reports would count the days by hand for each client, but I know there must be a better way.

I am assessing the impact of product price increases on volume (qty) and sales (Â£/$).

The prices are changed sporadically and at no set intervals. For example pries were changed on the 15th Jan and 13th Feb this year.

We have set reporting dates (calender months) so i am hoping to be able to divide the report which shows sales & qty's during the 15th Jan - 13th Feb segment and apportion them to the correct months.

I have the start & end dates of the calender months in cells A4:B18 and each time a new report is run (ie 15th Jan or 13th Feb, these dates go across the top i.e. cell C3 = 15th jan & D3 = 13th Feb.

I would like to return a % in cell C4 which relates to the amount of total days in the segment that relate to Jan (ie. 29 days in the segment, 16 relate to Jan so 55.2%).

Cell C5 would then return a % which relates to the amount of total days in the segment that relate to Feb (29 days in the segment, 13 relate to Feb so 44.8%).

Cells D4&D5 would return the next reporting segment and how many days in Jan/Feb respectively (the answer will be 0 but a constant formula acrosss all would be perfect. tried to give as much info as poss.

I have log data in two columns:

Column A: Date/time (at 30 minute intervals)

Column B: Numeric data

On the last row of each month, I’m trying to perform a SumProduct on the two columns and display that result in column C.

The end of the range is determined by the month in the current row.

I’m having difficulty finding the beginning of the range, though. I need to account for both the normal dynamic calendar days & the fact that I may get data starting mid-day and mid-month.

I have this formula, but I’m not sure how to make the first array dynamic or if this is even correct approach.

Manual

=IF(OR(MONTH(A1009)=A4)*(A$4:A$65536

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.

Example: 04/31/08 - 04/01/08 = 30 (days)

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.

Legend:

*LU = lesson units; 1 LU is 45 minutes

Holidays:

28-Nov-13

29-Nov-13

08-Dec-13

09-Dec-13

25-Dec-13

31-Dec-13

01-Jan-14

I need to count how many in a month per day X number is =. I originally used Countif -

=COUNTIF(B3,">25252525=36")+COUNTIF(V3,">=36")+COUNTIF(X3,">=36")+COUNTIF(Z3,">=36")

The formula above works, but i end up with several long strings of Countif. I'd like to know if there is a way wherein i can use a shorter formula.

I am using the following array to determine the total dollar of contracts reviewed in one month.

=SUMPRODUCT(($C$5:$C$3002>$H18)*($C$5:$C$3002<$I18)*(D$5:D$3002))

Column C has the actual Date

Column H the beginning of the month

Column I the end of the month and

Column D the dollar amount

Now I would like to count the number of contracts that fall in the following categories in a given month. The minimum number is in Column N and the maximum in Column O.

1-499,999

500,000-2,499,999

2,500,000-4,999,999

5,000,000-12,499,999

12,500,000-24,999,999

25,000,000-64,999,999

65,000,000+

I can get the count for each category but am having difficulty with the count in the specific month. Does any one have any suggestions - other than a pivot table?

I am attaching a small sample.

For example Employee A starts on March 16. Probation time is 90 days. Probation Ends is 6/14/09. The Benefits start date is 7/1/09, however I want this column to just say July.

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..

The formula I've used is thus :

Code:

=IF(EOMONTH(A13,0)EOMONTH($I$9,0),0,IF(EOMONTH(A13,0)>$I$9,$I$9-(EOMONTH($I$9,-1)),EOMONTH(A13,0)-(EOMONTH(A13,-1))))))

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

Jan-11

31

Feb-11

28

[Code].....

is there a formula that will say how many days there are in a month ?

B9 contains the a refrence to the first day of the month eg 1/7/2008 I want the cell above it (B8) to return 31. If the date reference is 1/6/2008 I want (B8) to return 30.

I'm using it to pro rata by the number of days in a month.
