Make sure that you've got a row with zeroes (or blanks) at the beginning of
the list, before week 1, then use =IF(A3-A2<1,A3-1-A2,"") and copy down, to
show the number of weeks absent in each absence period.

Thanks ashish, You seem to be a whizz at this :-)
I need to count the consecutive weeks together...i.e. Bob was off work in
weeks 1 and 2 and also 5,6 and 7 so that woud be 2 weeks and 3 weeks
consecutively taken off...do you know of a way to do this?

Hi,

If Bob's weeks worked are in range B2:B7, then the weeks missing would be

=52-count(B2:B7)
