Im in deep trouble, very very sorry,

i forgot to tell you that there will be work on monday after easter
sunday,
meaning the previous count should add 2. (1 day for 2007 and 1 day for
2008).

current workday count is 597+2=599
from 1/2/2007 to 1/2/2009 (inclusive)

my mistake

thanks for the right formula

I also came up with 600 at one point also, I think (if memory serves me
right). That was before I went through the additional rules regarding
holidays that fall on Saturday/Sunday. We may need to get the OP to
clarify
that.

Initially, in another discussion, he stated that their weekend holiday
rules
followed U.S. 'rules': Holiday falls on Saturday, it is observed on
Friday;
if it falls on Sunday it is observed on Monday. But there may be an
exception for something like Easter which will always fall on Sunday and
it
would seem somewhat unreasonable to observe it on Monday.

The fact that he seems to have a 6-day workweek, vs 5-day workweek may
play
into why the rules are laid out the we he stated above. I used the rules
above to come up with my numbers, so if the rule about Friday/Saturday is
in
error, so may my values.

I provided the 4-column, step by step 'solution' just as a check against
more compact formulas like you and Bob Phillips have provided, not as a
solution for the OP to actually use.

Like you, I noted that a couple of the dates in the list were outside of
the
range of dates he indicated are to be considered - my 'check' just
includes
the dates to be considered, so a lookup for 1/1/2007 won't find a result
and
won't count as one of the unpaid days.

By my calculation the result is 600. I excluded one each of the
duplicate
dates in the holidays list. Also note that there are 2 dates in the
holiday
list that are outside of the date range.

This doesn't make any sense (to me):

Excluding sundays and holidays
AND next monday if holiday falls on sunday,
AND saturday if holiday fall on friday...

Since both Friday and Saturday are regular workdays excluding Saturday
for a
Friday holiday is redundant.

=SUM(INT((WEEKDAY(start-{1,2,3,4,5,6},2)+end-start)/7))-SUMPRODUCT(--(holidays=start),--(holidays<=end))-SUMPRODUCT(--(WEEKDAY(holidays,2)=7),--(holidays=start),--(holidays<=end))

I used a somewhat brute force method to perhaps double check the
numbers
and
I come up with
732 days between 1/2/2007 1/2/2009 (inclusive)

During that period it appears that there are 137 days that meet the
exclude-it-date, so I end up with 596 (732-137+1) days that have to
be
paid
for.

By the way - in your list there are two dates that are duplicated:
Friday, September 14, 2007 is listed twice
Monday, September 15, 2008 is also listed twice

I think I probably know why, but thought I'd call that to your
attention.
