Add n business days to a given date ignoring holidays and weekends in python

Question

I\'m trying to add n (integer) working days to a given date, the date addition has to avoid the holidays and weekends (it\'s not included in the working days)

Answer 1

There is no real shortcut to do this. Try this approach:

1. Create a class which has a method skip(self, d) which returns True for dates that should be skipped.
2. Create a dictionary in the class which contains all holidays as date objects. Don't use datetime or similar because the fractions of a day will kill you.
3. Return True for any date that is in the dictionary or d.weekday() >= 5

To add N days, use this method:

def advance(d, days):
    delta = datetime.timedelta(1)

    for x in range(days):
        d = d + delta
        while holidayHelper.skip(d):
            d = d + delta

    return d
