class DateTime
  def next_business_day
      # if its a friday saturday or sunday
    if self.day > 4

      # calculate the remaining days to add to the current day
      remaining_days = 7 - self.day + 1

      return remaining_days.days.from_now
    else

      # return tomorrow
      return self.tomorrow
    end
  end
end

a = DateTime.now
a.next_business_day
