Robert,
Having looked at this again, I think there is a fault in the IF statement.
It SHOULD check the surd parts of the two dates as follows (using my cell
references):
IF((B2-INT(B2))<(A2-INT(A2)), <show DAYS - 1>, <show DAYS>) ... that is,
replace (B2-A2)<1 with (B2-INT(B2))<(A2-INT(A2)) in the expression.
where DAYS means the DATEDIF with the "MD" parameter

Robert,
Copied from my test sheet - change my A2 to J5 and my B2 to J6:
Try the following:
=TEXT(DATEDIF(A2,B2,"Y"),"0000")&"-"&TEXT(DATEDIF(A2,B2,"YM"),"00")&"-"&TEXT
((IF((B2-A2)<1,(DATEDIF(A2,B2,"MD")-1),DATEDIF(A2,B2,"MD"))),"00")&"
"&TEXT(B2-A2,"hh:mm")
(This gives a format of '0000-00-00 6:44' for your calculation. The IF
function - if you can see it! - is necessary to cope with the time of day
being less in J6 than in J5)
or: =DATEDIF(A2,B2,"Y")&"yrs, "&DATEDIF(A2,B2,"YM")&"mths,
"&(IF((B2-A2)<1,(DATEDIF(A2,B2,"MD")-1),DATEDIF(A2,B2,"MD")))&"dys,
"&TEXT(B2-A2,"hh:mm")
(just a rearrangement to give "0yrs, 0mths, 0dys 6:44"
An expansion of the final TEXT expression would, I think, give you the
format you quoted as the last of the two.

midnight?
Objective: How long did this person live?
If I format as yyyy-mm-dd HH:MM, and enter 1955-10-25 19:23 in J5, and enter
1955-10-26 02:07 in J6.
Entering =J6-J5 in cell J7, yields 1900-01-00 06:44. I know and understand
that "1900" is zero in this case, but does anyone have a suggestion how work
the formula so that the answer above would read:
"0000-00-00 06:44"
-or-
0yrs 0mths 0 dys 6hrs 44 mins
????
The last two formats would be easier for non-computer literate people to
understand. I prefer the YYYY-MM-DD HH:MM format if possible. It will be
faster for students to enter.
Thank you everyone.
Robert
