Select A2:B8

CFFormula is: =$B2$A2+6

Note the $ sign to lock the column but not the row.

Format to a color and OK your way out.

For me it colors B1, B2 and B6

Your row numbers appear to out by one in your example.

If you mean column B cannot be more than 7 days greater than column A, change
the $A2+6 to =$A2 which will then also color B7

Hi, I would like to use the conditional formatting. I can use it for numeric,
but how to count date for 2 column ?

If I want column B can not be 7 days more than column A. If not, Column B
will show a different colour. How can it be done ?

Suppose 2 b & 5 b will show a different colour. Many thanks
