a duration that could last several month.
d hh:mm

That format will only work up to 31 days, after that it rolls over.

I don't know of a number format that will handle this application. AFAIK,
you'd need to do something like:

=INT(A2-A1)&" "&TEXT(MOD(A2-A1,1),"h:mm")

Which is a text string.

Hi,
I need to display a duration that could last several month.
I make a difference between 2 dates and I apply the format mm/dd/ hh:mm.

It works fine except that it displays always 01 for the month.
For axample
18/06/2009 23:03
22/06/2009 07:21
result = 01/03 08:17
where it should be 00/03 08:17

In fact Excel treat this duration as a serial date. In that case the
minimun
value for the month is 1 for January.
Then the same problem is propagated in the chart that I make based on
that
column value.

Any help is welcome
