[craig@help]

Hi there!

Im wondering if you could help me out as im trying all kind of trick
to make what i want it to work, i have tried =if(or(a1>b1,a1<b2)
"x","y") function, (b1=01/01/2005, b2= 31/12/2005) it will work but i
no date has been input then it still show x

'm looking for fornulas/function that will help me with my work, se
below:
between 01/01/2005 and 31/12/2005 = "x"
between 01/01/2006 and 31/12/2006="Y"
if no date input then ignore it or leave it blank.

I would be grateful for your kind support.

=IF(ISBLANK(A1),"",IF((DATE(2005,1,1)<=A1)*(DATE(2005,12,31)>=A1),"X",IF((DATE(2006,1,1)<=A1)*(DATE(2006,12,31)>=A1),"Y","Out of Range")))

If your dates include times (example: 12/31/2005 4:30 PM), then you might
need this formula...

=IF(ISBLANK(A1),"",IF((DATE(2005,1,1)<=A1)*(DATE(2006,1,1)>A1),"X",IF((DATE(2006,1,1)<=A1)*(DATE(2007,1,1)>A1),"Y","Out of Range")))

IF(A1="","",IF(YEAR(A1)=2005,"X",IF(YEAR(A1)=2006,"Y")))
