Hi!

I wonder if someone can help me finding the right function.

I have a worksheet over dates. The left columns contains dates (my input)
and the right column contains a function A1+15, A2+15 and so on, dates 15
days forward. Now I want Excel to help me find the dates (in the right
column) that has passed. Is there a function for this? For example making
the
date red or fat.

Thanks!
