Hi I am trying to set up a sick leave list which will work out the
cumulative
total for the last 12 months (from last day of last sick entry).

The problem I have as the ist is added to I need a function/formula to
work
out 12 months from last date and then add up the no. of sick days from
then
to last date.

Below is the chart

Column 1 Start date of sickness
column 2 End date
Column 3 the number of days sick in period (column 2 less column 1 in
days)
column 4 the number of days sick in period above excluding week ends
(column
2 less column 1 less weekends in days)
column 5 total sick days in last 12 months from date in column 2 going
back
a year including weekends
column 6 total sick days in last 12 months from date in column 2 going
back
a year excluding weekends

What function or formulas can I use to calculate column 3,4,5 & 6.

3 - =B2-A2 and fornat as general

4 - =NETWORKDAYS(A2,B2)

5 -
=IF(B4=DATE(YEAR(TODAY())-1,MONTH(TODAY()),DAY(TODAY())),B4-MAX(A4,DATE(YEAR(TODAY())-1,MONTH(TODAY()),DAY(TODAY()))-1),0)

6 - =IF(B4=DATE(YEAR(TODAY())-1,MONTH(TODAY()),DAY(TODAY())),
NETWORKDAYS(MAX(A4,DATE(YEAR(TODAY())-1,MONTH(TODAY()),DAY(TODAY()))),B4),0)
