How to leave blank if no data entered

[Peace2019]

Hi please forgive my lack of experience I’m a newbie.

How can I have a blank cell if no data entered I’ve tried stuff I’ve found on the internet but no luck. Thanks

=IF(DATEDIF(C2, TODAY(),"y")=0,"",DATEDIF(C2, TODAY(),"y")&" years, ")& IF(DATEDIF(C2, TODAY(),"ym")=0,"",DATEDIF(C2, TODAY(),"ym")&" months, ")& IF(DATEDIF(C2, TODAY(),"md")=0,"",DATEDIF(C2, TODAY(),"md")&" days")

Hi. Just use an IF test at the start:

=IF(C2="","",IF(DATEDIF(C2,TODAY(),"y")=0,"",DATEDIF(C2,TODAY(),"y")&" years, ")&IF(DATEDIF(C2,TODAY(),"ym")=0,"",DATEDIF(C2,TODAY(),"ym")&" months, ")&IF(DATEDIF(C2,TODAY(),"md")=0,"",DATEDIF(C2,TODAY(),"md")&" days"))
