Hello,

I am trying to determine a formula that will calculate the the number of days that fall within a certain month.

Example: April
[TABLE="width: 435"]
<tbody>[TR]
[TD="align: left"]04/24/2010[/TD]
[TD]04/02/2011[/TD]
[TD]2[/TD]
[/TR]
[TR]
[TD="align: left"]03/02/2011[/TD]
[TD]04/03/2011[/TD]
[TD]3[/TD]
[/TR]
</tbody><colgroup><col><col><col></colgroup>[/TABLE]


I need to do this for the months of April to July so I can calculate a proration based on the days falling in a specific month.

Please assist :)

Hello,

When I use this formula it returns a value of how many days are in the specific month as opposed to the count of days between the period. In the three cases below it should show 1 for April and 0's for the other months. Also, I am running 2007 so the EOMONTH is available.

Please advise!

Excel Facts

Remove leading & trailing spaces
Save as CSV to remove all leading and trailing spaces. It is faster than using TRIM().

Note that I use the 1st of the month dates for the column headers.

Here's a small sample file that demonstrates this.

I got it! I had everything correct. What happened was the worksheet that I exported was not actually recognizing formatted dates as dates. By using the Text to columns feature and get the dates to 'actually' format as a date and was able to get the formula to calculate correctly.

This sent me for a whirlwind!

Thank you so much, I know I can always count on you guys!
