DUE. What ought to be paid; what may be demanded. It differs from owing in this, that, sometimes, what is owing is not due; a note, payable thirty days after date, is owing immediately after it is delivered to the payee, but it is not due until the thirty days have elapsed.
2. Bills of exchange, and promissory notes, are not, due until the end of the three days of grace, (q. v.) unless the last of these days happen to fall on a Sunday, or other holyday, when it becomes due on the Saturday before, and not on the Monday following.
