Daily Average
 

I prepare a report containing the daily average for every month in the year.
How can I set the formula (prefer not VBA) which can automatically identify
number of days for every month, i.e. in August, get the average of dividing
by 31; in September, get the average by dividing of 30 and so on ?

Daily Average
 

Having year in A1, month No in B1:
=DAY(DATE(A1,B1+1,0))

Stefi

If A1 contains a date then =DAY(EOMONTH(A1,0)) will return the number of days
in that month.
Hope this helps

Thanks Ron & Stefi.

My MS office returns that the EMONTH function cannot be found. My MS office
is Office XP. Does the function not inclduding in this version.

The Date(year, month, day) formula is found worked. Pls be kind to explain
that :
- why the month value should add 1, i.e. B1+1
- does the value in B1 must be alphabet

Thanks a lot,

To get help on EOMONTH, type EOMONTH into Excel help.

DATE(A1,B1+1,1) is the first day of the month after B1; DATE(A1,B1+1,0) is
1 day before that, and is therefore the last day of month B1.

Stefi said "month No in B1" so, no, the month number should *not* be
alphabet; it should be 10, not "ten".

If you have Jan,Feb, etc. in column B, then you can use (in UK date system)
=DAY(DATE($A$1,MONTH(DATEVALUE("1/"&B1&"/"&$A$1))+1,0))
or (in US date system)

=DAY(DATE($A$1,MONTH(DATEVALUE(B1&"/1/"&$A$1))+1,0))

For EOMONTH you have to enable Analisys Toolpak.

DATE(year,month+1,0) is a workaround: 0th day of a month equals last day of
the previous month by Excel calculation method.

Hi, David,

When I enter the formula EOMONTH, it returns #NAME?

And what did it say when you typed EOMONTH into Excel help, as I suggested?
