Counting Date Events
In a spreadsheet I have dates and times of events (example 10/2/2009 03:12)
in cells F2:S233. I need to count the events by month, ie January had 'x' number of events, February had 'x' number of events, and so on. For my need, the time is irrelevant. Your suggestion would be appreciated. Thanks. |

Counting Date Events
Hi
This will count number of events in January in range F2:S233 =COUNTIF(F2:S233;"=" &DATE(2009;1;1))-COUNTIF(F2:S233;"=" & DATE(2009;2;1)) The second parameter in the DATE function is the month, and has to be increased by 1 to count events for February. Hopes this helps. .... Per "wally" skrev i meddelelsen ... In a spreadsheet I have dates and times of events (example 10/2/2009 03:12) in cells F2:S233.

Another one:
=SUMPRODUCT(--(TEXT(F2:S233,"yyyymm")="200901")) This will calculate slower than Per's suggestion--especially if the range gets larger, but it's easier to type <vbg. wally wrote: In a spreadsheet I have dates and times of events (example 10/2/2009 03:12) in cells F2:S233.

Per;
I'm sorry, but I could not make your suggestion work. When pressing ENTER an error dialog box appears and the first S233 is highlighted. Can you tell me what I'm doing wrong? I would like to better understand your suggestion. Thanks.

Counting Date Events
Try replacing all the semi-colons with commas. Some international locations
use the semi-colon as the argument separator and some use the comma. Even if you get the formula straightened out and Excel will accept it I'm wondering if Excel will recognize your entries as true Excel dates/times: (example 10/2/2009 03:12) If I enter 10/2/2009 03:12 in a cell Excel treats it as a TEXT string. If I remove the leading 0 in the time portion *then* Excel treats it as a true Excel date/time. -- Biff Microsoft Excel MVP "wally" wrote in message ...

Biff: I really appreciate that you tried to work this out. It stilll
doesn't work. I feel you are right that Excel will not recognize the entries. You might look at the suggestion of Dave Peterson where he is treating this as a text string. That worked! It did what I was hoping to achieve. I would still like to understand the construction and use of the symbols used in the proposal you tried to fix. Can you recommend a resource that would help? I can't tell you how much I appreciate 'My People'... You are the best. "T. Valko" wrote: Try replacing all the semi-colons with commas.
