count number of weeks missing for each individual in a database

[pumpkin]

Hi,

I need to measure attendace for the employees. I have a list of weeks worked
(eg. below) for each employee (numbered from 1-54) and I need to work out the
weeks that have not been worked and whether they are consecutive or not.

Please help

Hi,

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

=52-count(B2:B7)

The number of missing weeks is =54-COUNT(A2:A55)
I will let someone else answer the non-consecutive part. The easiest way
would be with a helper column, but probably someone can think of a more
direct way.

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?

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.
