I'm used the formula at the beginning of this topic to calculate how long my employees have worked so I can setup quarterly progress reviews with them. I have the number generated from a formula that gives me how many days from hire date until current date. What is the change in the formula to go from Hire date to the brake down of year/month/day?

In my situation, I wanted years and months if possible; if not, I wanted just months or just days. I ended up with:
=IF(cellcontainingdays="","",IF(DATEDIF(0,cellcontainingdays,"y")=0,"",CONCATENATE(DATEDIF(0,cellcontainingdays,"y")," years")) & IF(DATEDIF(0,cellcontainingdays,"ym")=0,"",IF(AND(DATEDIF(0,cellcontainingdays,"ym")<>0,DATEDIF(0,cellcontainingdays,"y")=0),CONCATENATE(DATEDIF(0,cellcontainingdays,"ym")," months"),CONCATENATE(", ",DATEDIF(0,cellcontainingdays,"ym")," months"))) & IF(DATEDIF(0,cellcontainingdays,"md")=0,"",IF(AND(DATEDIF(0,cellcontainingdays,"md")<>0,DATEDIF(0,cellcontainingdays,"y")=0,DATEDIF(0,cellcontainingdays,"ym")=0),CONCATENATE(DATEDIF(0,cellcontainingdays,"md")," days"),"")))
