Highlighting a cell based on cell condition

Brass Contributor

Hello, I need help with creating a highlighting condition based on dates. I would want colum M (previously positive) to highlight IF the date in cell T (Test 1 date) is within 60 days of each other.

Select cells in column M, from M2 down. M2 should be the active cell in the selection.

On the Home tab of the ribbon, click Conditional Formatting > New Rule...
Select 'Use a formula to determine which cells to format'.
Enter the formula


=AND(T2<>"', T2<M2+60)


=AND(T2<>"", T2<M2+60)

Click Format...
Activate the Fill tab.
Select a highlight color.
Click OK, then click OK again.

Thank you!

Do you use comma as decimal separator? If so, use semicolon instead of comma in the formula:


=AND(T2<>""; T2<M2+60)


Oops, sorry! I had a typo. It should be


=AND(T2<>"", T2<M2+60)

the formula worked, but the highlighting condition isnt working when I type in the dates.


Could you attach a small sample workbook demonstrating the problem (without sensitive data), or if that is not possible, make it available through OneDrive, Google Drive, Dropbox or similar?

@Hans Vogelaar yes I have attached the blank document


Thanks. The problem is you applied the rule to the entire column $M:$M instead of what I suggested, but the formula still referred to M2 and T2. If the rule applies to the entire column, the formula should refer to M1 and T1.

=AND(T1<>"", T1<M1+60)

See the attached version. (Edited to attach the correct version)

thank you so much!
