calculate time periods

[umba-sr]

Hi,

This is something that's bothered me for some time, but I was never able to
discover the solution.

I have a list of employees, for example, and some of them have been in the
company since their first employment, but some of them haven't. Now, the
other group is the one that worries me.

Say, there is one such employee who had worked in some company prior to
this, and then didn't work at all for several months, and only then joined
our company.
I know that to calculate time difference, function is DATEDIF, and when I
add parametres to get years, months and days, formula and results look
something like this:
=DATEDIF(E4,TODAY(),"Y")&" years, " & DATEDIF(E4,TODAY(),"ym")&" months, " &
DATEDIF(E4,TODAY(),"md")&" days"

12 years, 5 months, 26 days

And this is the period he spent in our company, plus I have the same formula
for the time he spent in previous company, only with specific date instead of
TODAY().

Actual question is: How do I add these two results to get total of years,
months and days?

If dates spent at previous company were, say, C4 to D4

=DATEDIF(C4,TODAY()-E4+D4,"Y")&" years, " & DATEDIF(C4,TODAY()-E4+D4,"ym")&" months, " &
DATEDIF(C4,TODAY()-E4+D4,"md")&" days"
