First working day of the month

[Hedgie]

I need a formula to calculate the first working day of the month. At present
I am using:

=DATE(YEAR(B9),MONTH(B9),1+IF(WEEKDAY(DATE(YEAR(B9),MONTH(B9),1))=7,2,IF(WEEKDAY(DATE(YEAR(B9),MONTH(B9),1))=1,1,0)))

where B9 is today's date. However, this does not take into account bank
holidays (such as 1 January).

This spreadsheet is for use by other users and needs to be as automated as
possible so I don't want to override the date cell if I can help it. Does
anyone have a simple formula to calculate the first working day of each
month, taking into account bank holidays?

Thanks

Use

=WORKDAY(B9-DAY(B9),1,holidays)

where holidays is a list of holiday dates.

If you (and everyone who will use the workbook) has
the Analysis ToolPak add-in installed, you could use
the WORKDAY function.

However, if there is risk that some of the users will NOT have that add-in,
try this:

B9: (a date)
G1:G10 contains a list of bank holidays.....eg G1: 2008-01-01, etc

This formula (in sections, for readability) returns
the 1st workday of the month:

=MIN(IF((COUNTIF(G1:G10,B9-DAY(B9)+{1,2,3,4,5,6,7})=0)*
(WEEKDAY(B9-DAY(B9)+{1,2,3,4,5,6,7},2)<6),(B9-DAY(B9)+{1,2,3,4,5,6,7})))

Is that something you can work with?
