Can anyone give me ideas on how to create and use holiday calendar tables.

I need to calculate South African school days, excluding weekends and holidays.
In my schoolterms table I have got columns StartDate and EndDate, I tried using DATEDIFF but it includes weekends and holidays.

Solution 1

holiday table
NUMERIC ID
DATE HOLIDAY_DATE
VARCHAR COUNTRY

I get the feeling that's not enough for you, but you need specify your question.

The algorithm:

List schoolDays = empty list

Loop over each date in your date range
  if(IsSchoolDay)
    Add current date to schoolDays

return schoolDays

IsSchoolDay is defined as

IsSchoolDay (Date date)

is date a saturday or sunday
  return false
is date in the holiday table
  return false

return true
