Whenever in any act or statute of the state of North Dakota providing for the publication of a notice the phrase "successive weeks" is used, the word weeks must be construed to mean calendar weeks, and the publication upon any day in a week is sufficient publication for that week if at least five days intervene between such publication and the publications immediately preceding and immediately following. All publications heretofore or hereafter made in accordance with the provisions of this section are deemed legal and valid.
