Good afternoon,

Apologies if this query has been raised to death but I am quite confused about how to conditionally format dates.

Case:
I have a list of book last loaned dates
They are allowed to keep the books for one year
I want to highlight the ones that have expired

Say June-18 and I want to highlight it because it is not June-19 but it will highlight to green once I change to December-18

Kind regards,
Cleric
