# Revision history [back]

I found a solution myself with the following formula:

=IF(MONTH(C2)=MONTH(O2),TEXT(DATE(YEAR(C2),MONTH(C2),DAY(C2)),"mmmm"),CONCATENATE(TEXT(DATE(YEAR(C2),MONTH(C2),DAY(C2)),"mmmm"),"/",TEXT(DATE(YEAR(O2),MONTH(O2),DAY(2)),"mmmm")))


This seems too cumbersome but it is functional.
