Conditional Formatting: Highlight a date if it's been 4 years or more

[Dais Helper]

I have a column full of various dates -- so far the oldest one is from 2017. I am allowed to get rid of these papers after four years. So 2021 in this case but not 1/1/21, whatever the exact date is or later I would be able to safely get rid of the paper.

So I want to highlight the cells as each one expires as they each reach their individual deadline in 4 years from the date listed in the column.

I found this formula in the forum and thought it would work, but it did not.
=DATEDIF(CD2,TODAY(),"Y")>=4

It highlighted a date clearly within 4 years -- like 2/6/20 & 10/14/19 --- it left some clear as it was supposed to then these chunks of column are highlighted. And it highlighted blank cells.

Is there a formula for conditional highlighting that I can use to highlight only if the date has reached 4 or more years; also do not highlight blank cells?

Is there a Formula that can do this. I really am not comfortable with VBA. It's not imperative that this occurs, so I can do without if VBA is needed.

Thank you very much for your time and assistance. ?

Select CD2 to end of data & use this formula in conditional formatting
=AND(CD2<>"",EDATE(CD2,48)<TODAY())

Try
=and(EDATE(TODAY(),-48)>CD2,CD2<>"")

=AND(CD2<>"",EDATE(CD2,48)<TODAY())

thank you -- I wasn't able to get your formula to work correctly. When I tested some dates -- it looked fine until I entered a date I KNEW to be 4 years or beyond and instead of highlighting THAT date it highlighted the 2020 date above it. But I WAS able to get Toadstool's formula to work

Thank you very much. This formula works well for me ?

That sounds as though the applies to range was from CD1 not CD2. But glad you've got a solution & thanks for the feedback.
