Number of days left in the Month?

[Guest]

Hello!

I need to write a formula that will calculate how many days are left in a
specific month and can't seem to get a working one. Seems like it should be
relatively easy.

Example:

Cell A1 contains date of 03/09/98.
I need cell B1 to contain the resulting number as 22 days remaining.

Cell A2 contains date of 04/03/98
Cell B2 should contain the resulting number as 27 days remaining.

I tried this:
=(DAY(DATE(YEAR(A2),MONTH(A2)+1,0))-(DAY(A2)))
Which actually works, but I was just wondering if there was a less
complicated way? Trying to explain this one to the person requesting the
spreadsheet may not be the easiest of jobs and I know I'll get questioned on
it.

Any help would be appreciated!
Cheers,
Elf

Hi Elf,

Slightly less complicated:

=DAY(EOMONTH(A1,0))-DAY(A1)

This needs Analysis Toolpak to be installed. If you get a #NAME error:

Tools>Add-ins, check Analysis Toolpak

Hi Elf,

=A1/24/60/60

Format Custom as d:hh:mm:ss

Elf,

You can use EOMONTH. You need to have the Analysis ToolPak. To
install go to Tools>Addins. Select the Analysis ToolPak check box.
Then you can apply this formula in A2.

=EOMONTH(A1,0)-A1

Format A2 as General. You can then copy this down as needed.

Of course, much simpler:

=EOMONTH(A1,0)-A1

Sorry about this one

If you don't want to deal with the Analysis Tool Pak, you could use the
formula:

=32-DAY(A1)-DAY(A1-DAY(A1)+32)

Format as General or Number

If you don't want if install the Analysis Toolpak then slightly shorter and
still using your formula:

=DATE(YEAR(A2),MONTH(A2)+1,0)-A2

if you format the cell as General there is no need for the DAY() functions.

=32-DAY(A1)-DAY(A1-DAY(A1)+32)

If Elf thought that he was going to have trouble explaining it
before............

Explanations? Hmmph.

Well, with any date:

A1-DAY(A1) will always give the last day of the preceding month.

Add 32 to get into the following month.

32+ A1-Day(A1)

Then subtract the DAY of that date to get the last date of the current month.

32+A1-DAY(A1) - DAY(32+A1-DAY(A1))

From that subtract the current date in A1:

-A1 + 32+A1-DAY(A1) - DAY(32+A1-DAY(A1))

Remove the values that cancel out (-A1+A1)

32-DAY(A1) - DAY(32+A1-DAY(A1))

Nice explanation Ron, I especially like the:

Remove the values that cancel out (-A1+A1)

part. Lets hope that it satisfies Elf's colleague
