I have a table with

Column C = Payment Due Date
Column E = List of Public Holiday
with the first row as header and subsesquent rows as the actual data

what i want to do is to auto generate the payment due date of each
invoices so that it won't falls on weekends and public holiday. for
example, if [Invoice Date] + [Days of Credit Granted] falls on a
saturday, then the due date will be push forward 2 days to monday.

i came out with a formula which works pretty fine given that there's
no consecutive non-working days of more than 4 days (which would be
quite rare). i wonder if there's an easier and cleaner way to do this
=IF(A2="","",IF(ISNUMBER(MATCH(A2+B2,$E:$E,0)),IF (ISNUMBER(MATCH
(A2+B2+1,$E:$E,0)),IF(WEEKDAY(A2+B2+2,2)<6,A2+B2+ 2,CHOOSE(WEEKDAY
(A2+B2+2,2)-5,IF(ISNUMBER(MATCH(A2+B2+4,$E:$E,0)),A2+B2+5,A2+B 2+4),IF
(ISNUMBER(MATCH(A2+B2+3,$E:$E,0)),A2+B2+4,A2+B2+3 ))),IF(WEEKDAY
(A2+B2+1,2)<6,A2+B2+1,CHOOSE(WEEKDAY(A2+B2+1,2)-5,IF(ISNUMBER(MATCH
(A2+B2+3,$E:$E,0)),A2+B2+4,A2+B2+3),IF(ISNUMBER(M ATCH(A2+B2+2,$E:$E,
0)),A2+B2+3,A2+B2+2)))),IF(WEEKDAY(A2+B2,2)<6,A2+ B2,CHOOSE(WEEKDAY
(A2+B2,2)-5,IF(ISNUMBER(MATCH(A2+B2+2,$E:$E,0)),IF(ISNUMBER( MATCH
(A2+B2+3,$E:$E,0)),A2+B2+4,A2+B2+3),A2+B2+2),IF(I SNUMBER(MATCH
(A2+B2+1,$E:$E,0)),IF(ISNUMBER(MATCH(A2+B2+2,$E:$ E,
0)),A2+B2+3,A2+B2+2),A2+B2+1)))))

Thanks for ur time : )

=if(a2="","",WORKDAY(A2+B2-1,1,E2:E100))

I would use a smaller range for holidays than the entire column.

If this formula returns the #NAME error, and you are using a version of Excel
prior to 2007, look at HELP for the WORKDAY function for instructions to
install the Analysis ToolPak.

thanks Bob and Ron for the reply, Ron's reply gives me the result i
wanted. It helps a lot : )

Maybe i didn't make myself very clear so Bob gets carried away, i'm
not calculating workdays, but the effective last due date of invoices.
Just for example, one of my customer buys a ton of coal on 1 Jan 2010
(fri), he was granted 30 days of credit, thus, the due date should be
1 Jan 2010 + 30 days = 31 Jan 2010 (sun), but it falls on a Sunday,
when my office is not operating. So, I allow the customer to pay on
the next working day, but the next day, 1 Feb 2010 (mon) happens to be
a public holiday here in Kuala Lumpur, Malaysia, so the last due date
is pushed another days forward to 2 Feb 2010 (tue). Instead of 2 Feb
2010, the first formula gives me 15 Feb 2010.
