For example, if you have dates in the range B4:G11, and want to highlight cells that occur in the next 30 days, select the range and create a new CF rule that uses this formula: Note: it’s important that CF formulas be entered relative to the “active cell” in the selection, which is assumed to be B4 in this case. Once you save the rule, you’ll see the dates occurring in the next 30 days highlighted.
Variable days
Of course, you can adjust days to any value you like:
Use other cells for input
You don’t need to hard-code the dates into the rule. To make a more flexible rule, you can use other cells like variables in the formula. For example, you can name cell E2 “days” and rewrite the formula like so: When you change either date, the conditional formatting rule will respond instantly. By using other cells for input, and naming them as named ranges, you make the conditional formatting interactive and the formula is simpler and easier to read.
