countif
I have a column with 3 years worth of random dates (2006, 2007, and 2008)
with the data is set up as Date. I want to count the number of date before 1/1/2007. I am using countif(C4:C299,"=1/1/2007"), the return value is 0. When i do countif(C4:C299, "9/13/2006"), it does result in a correct value. Only when i use < or sign then the software won't count. Any suggestion? Thanks for your input. |

Try
=COUNTIF(A:A,"<=" & DATE(2007,1,1)) If this post helps click Yes --------------- Jacob Skaria "kakymoau" wrote: I have a column with 3 years worth of random dates (2006, 2007, and 2008) with the data is set up as Date.

Presumably you have a cell in your worksheet that holds the date condition
(this can be entered into cell A1 using =DATE(2006,1,1) or whatever date you need to test). If your random dates i.e. 2006, 2007 etc are indeed numbers then the following formula should do the trick. =COUNT(IF(yourdaterange<YEAR(A1),yourdaterange,"") ) This should be entered as an array formula. Hope this helps Regards Paul "kakymoau" wrote in message ... I have a column with 3 years worth of random dates (2006, 2007, and 2008) with the data is set up as Date.
