(2) A cheque is not invalid by reason only that:
(a) it is not dated;
(b) it is antedated or post - dated; or
(c) the date it bears is a Sunday.
(3) For the purpose of determining whether a post - dated instrument is a cheque, the fact that the instrument is post - dated shall be disregarded.
(4) A cheque is not incomplete or irregular on its face by reason only that it is post - dated (whether or not the date has arrived).
