How to calculate next, previous business day in Rails?

Question

How to calculate next and previous business days in Rails?

Answer 1

I realise that this is an old thread, but I just had to work this one out for myself and I was looking for a very short bit of code that was trivial to modify if a business had weird opening days (like "closed Sunday/Monday").

def next_business_day(from_day)
  workdays = [1,2,3,4,5,6]
  test_day = from_day + 1.day
  return workdays.include?(test_day.wday) ? test_day : next_business_day(test_day)
end

I suppose it could be shortened again to something like this, but I think it becomes less obvious

def next_business_day(from_day)
  test_day = from_day + 1.day
  [1,2,3,4,5,6].include?(test_day.wday) ? test_day : next_business_day(test_day)
end
