[Boost-users] DateTime library - how to count "working days"?

I need to find a day that stands 30 working days from a specific date, 
ignoring holidays. Currently I am doing it like this:

boost::gregorian::date lastdate;
int maxdays(30);
for (int i = maxdays; i != 0; --i)
{
        // skip weekends
        gregorian_calendar::day_of_week_type dow = lastdate.day_of_week();
        while ( (dow == Sunday ) || (dow == Saturday) )
        {
              lastdate -= boost::gregorian::date_duration(1);
              dow = lastdate.day_of_week();
        }
        lastdate -= boost::gregorian::date_duration(1);
}

I did not find the iterator that can do it cleaner, but may be there is one?

Thanks.
