Conditional formating dates

[Teeny]

I have a range of dates in a column and I would like it if I could highlight
any date that is more that 3 years old.

So if the date reads 02/10/2004 this should be highlighted red.

I would really appriciate a bit of help.

CF formula is:

=DATEDIF(A2,TODAY(),"y")>=3

 

[Jacob Skaria]

1. Select the cell/Range (say A1:A10). Please note that the cell reference A1
mentioned in the formula is the active cell in the selection. Active cell
will have a white background even after selection
2. From menu Format>Conditional Formatting>
3. For Condition1>Select 'Formula Is' and enter the below formula
=AND(A1>0,DATEDIF(A1,TODAY(),"y")>3)

4. Click Format Button>Pattern and select your color (say Red)
5. Hit OK

PS: If you are using XL2007 Goto Home tab>Styles>Conditional
Formatting>Manage rules>New rule>Use a formula to determine which cells to
format. Enter the formula in the box below.
