I'm a Haskell-newbie so I can't give the Haskell code for this, but in 
"pseudo-code" it would be something like this -

holidays_list = ["09JAN", "06FEB", ..... ]   ( This will vary depending 
on country  ) 

if myday not in holidays_list and day(myday) in ["Mon", "Tue", "Wed", 
"Thu", "Fri"]
  then business_day(myday) = "Yes"
  else business_day(myday) = "No"

Some countries have a "Holidays Act" or similar legislation which 
specifies the holidays for the current year and the next few years.

Hope this helps.... :)
