Robert, Isolate the last 5 characters in the string in each case, then subtract one from the other and format it as "hh:mm". In fact, the easiest way would be to replace all your formulae with this sompler one: =TEXT(INT(O3-O2),"#")&" "&(TEXT((O3-O2)-INT(O3-O2),"hh:mm")) Don't worry that O2 and O3 are formatted as text rather than dates; I've tested this and it works fine.

Given O2 = 1972-08-09 07:32 N2 = 1972-08-22 09:30 The O2 cell is the date & time of birth, the N2 cell is the date and time of death. Using Datedif in M2, I have: =TEXT(DATEDIF(N13,O13,"y"),"0000")&"-"&TEXT(DATEDIF(N13,O13,"m"),"00")&" -"&T EXT(DATEDIF(N13,O13,"d"),"00") which gives me: 0000-00-13. How do I calculate and append the hours & minutes to this so that the result reads: 0000-00-13 01:58 That would read the person lived 13 days, one hour, and 58 minutes. ?? Datedif will not work with Time, or will it? Thank you.
