Blank cell if no calculation required

Please help I have the below calculation

=YEAR(C33)-YEAR(G3)

If Cell C33 is empty instead of showing 0 in the sum cell I would like it to be blank

hi Unsnz. wow a 2nd post after joining for 9 years? what happens if C33 is Dec 2012 & G3 is Jan 2013? do you consider that to be 1 year? you should use the DATEDIF formula instead for more accuracy:
=IF(C3="","",DATEDIF(C3,G3,"y"))

"y" stands for years between the 2 dates.

if G3 might be a blank too, then:
=IF(OR(C3="",G3=""),"",DATEDIF(C3,G3,"y"))

also consider updating your Excel version in your profile here by going to the Settings -> Edit Profile -> My Microsoft Office Version
