Counting Dates

[Mark Solesbury]

I have a column with lots of dates in.

I want a formula to count the number of dates, ie jan 2006 = 12

Any ideas,
Ive tried CountIf, and 2006 but i think the date formatting is messing
with it.

Try this:

=SUMPRODUCT(--(TEXT(A1:A100,"mmm yyyy")="Jan 2006"))

Try:

=SUMPRODUCT((MONTH(A1:A100)=1)*(YEAR(A1:A100)=2008))

Change the month number, year and range to suit.

Hi Mark.

Here are couple of alternatives:

=SUMPRODUCT((MONTH(A2:A37)=5)*(YEAR(A2:A37)=2008))

=SUM((A2:A37>=D3)*(A2:A37<=E3))
here you enter the first and last day of a month in the cells D3 and E3.
This formula is an array formula so you press Shift+Ctrl+Enter to enter it.

=SUMPRODUCT(--((TEXT(A2:A37,"M YY")="5 08")))
or its equivalent array version
=SUM(N((TEXT(A2:A37,"M YY")="5 08")))

All of these approaches assume the date in the range are entered as dates
not text.
