hi,
i am trying to count the number of times a date repeats. eg: 4/1/07 4/1/07 4/2/07 4/2/07 4/3/07 .. .. .. 4/30/07 4/30/07 ect... for the whole month data corralates with number of visits per day. i have created a helper colum B with number 1-31, and used the following =SUMPRODUCT(--$A$2:$A$1000=$B2),--($A$2:$A$1000<$B$3)) where A is data, B is helper returns 0 in all. formated to gen number. have tried several diff formats. have also tried =COUNT(A2:A1000)-SUMPRODUCT((B2:B2000<")/COUNTIF(B2:B1000,B2:B1000+(B2:B1000=""))) have also tried =SUMIF(A1:A1000,"<"&DATE(4/1/07),B1:B31-SUMIF(A1:A1000,+<"&DATE(4,1,07),B1:B31) It initially returned 0 then next time thru returned N/A i have tried xldynamic.com i'm sure there is an easirer way to do this. i'm terrible with formulas, but i'm chugging at it and i think i'm over my head... thanks in advance -- dr350x |

Consider using a Pivot Table. It will produce a nice table that lists each
date uniquely and the number of time the date occurs in your table. For example: tades 6/16/2007 6/16/2007 6/16/2007 6/16/2007 6/16/2007 6/16/2007 6/16/2007 6/16/2007 6/16/2007 6/15/2007 6/15/2007 6/15/2007 6/15/2007 6/15/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 6/17/2007 can produce a table like: Count of tades tades Total 6/15/2007 5 6/16/2007 9 6/17/2007 22 (blank) Grand Total 36 see: http://peltiertech.com/Excel/Pivots/pivotstart.htm -- Gary''s Student - gsnu200730 "dr350x" wrote: hi, i am trying to count the number of times a date repeats. eg: 4/1/07 4/1/07 4/2/07 4/2/07 4/3/07 . . . 4/30/07 4/30/07 ect... for the whole month data corralates with number of visits per day. i have created a helper colum B with number 1-31, and used the following =SUMPRODUCT(--$A$2:$A$1000=$B2),--($A$2:$A$1000<$B$3)) where A is data, B is helper returns 0 in all. formated to gen number. have tried several diff formats. have also tried =COUNT(A2:A1000)-SUMPRODUCT((B2:B2000<")/COUNTIF(B2:B1000,B2:B1000+(B2:B1000=""))) have also tried =SUMIF(A1:A1000,"<"&DATE(4/1/07),B1:B31-SUMIF(A1:A1000,+<"&DATE(4,1,07),B1:B31) It initially returned 0 then next time thru returned N/A i have tried xldynamic.com i'm sure there is an easirer way to do this. i'm terrible with formulas, but i'm chugging at it and i think i'm over my head... thanks in advance -- dr350x |

I'd also put the real dates in the helper column, but you could use this, too:
