formula for adding up 3 different start and finish times

Hi. Can any one tell me the formula for adding up 3 different start and
finish times within a 24 hour period.

I have set up a time sheet that has shifts of Morning, Afternoon and Evening
i enter in my start and finish times for each shift but can not figure out
how to add them all together.

Hi

With your data in A2:F2 enter in G2
=MOD(B2-A2,1)+MOD(D2-C2,1)+MOD(F2-E2,1)
Format G2 as hh:mm

The MOD part of the formula will deal with any shifts crossing the 24
hour barrier.

If you want your result in decimal hours, then you would need
=24*(MOD(B2-A2,1)+MOD(D2-C2,1)+MOD(F2-E2,1))
and format the cell to the number of decimals you require.
This is because Excel stores times as a fraction of a day (24 hours).

Hi Roger
thanks for your response. this one works if every cell is populated but on
quite a few occasions there will be nothing in some of the cells. An example
of what i have is as follows

Start Finish Start Finish Start Finish Total
05:00 12:00 17:00 00:00
09:00 13:00 14:00 17:00 18:00 11:00

So i am finding that on the days where no time has been entered then the
formula does not work.

Hi

then try

=if(count(A2:B2)=2,MOD(B2-A2,1),0)+if count(C22)=2,
MOD(D2-C2,1),0)+if(count(E2:F2)=2,MOD(F2-E2,1),0)

You'll need to explain what "does not work" means, because Roger's formula
worked for me when I tested it, including the sample where there was no
start/finish time.
