Dates: How many entries per week?
I have a spreadsheet with entries by date. I would like to know how many
entries per week there are. I have created a list of beginning dates for weeks, as in a1=8/17/05, a2=8/24/05 and was attempting to count for datea1 and <a2. Is there an easy way to do this? Alternative is there a way to count how many entries per month? thanks |

Dates: How many entries per week?
If your dates are in cells A5:A50, you can try this matrix formula:
=SUM(IF(AND(A5:A50A1;A5:A50<A2);1;0)) Remember that matrix formulas MUST be finished with a CTRL+SHIFT+ENTER -- Rogerio Takejame Americana - Sao Paulo - Brazil "Jill" wrote: I have a spreadsheet with entries by date.

Dates: How many entries per week?
This is not working for me. I get an error message about Logical1 that points
to a1. Should A1 not be a date? I have it as the 8/7/05 of the first date to check against.

Dates: How many entries per week?
OK, try this one that is simpler:
=SUM((A5:A50A1)*(A5:A50<A2)) Don't forget the CTRL+SHIFT+ENTER -- Rogerio Takejame Americana - Sao Paulo - Brazil "Jill" wrote: This is not working for me.

Rogerio, no error message now, but an answer of 0 which is clearly not true.
