The question sometimes arises whether a man is entitled to vote at an election held on the day preceding the twenty-first anniversary of his birth. Blackstone, in his "Commentaries," book 1, page 463, says: "Full age in male or female is 21 years, which age is completed on the day preceding the anniversary of a person's birth, who, till that time, is an infant, and so styled in law." The late Chief Justice Sharswood, in his edition of Blackstone's "Commentaries," quotes Christian's note on the above as follows: "If he is born on the 16th day of February, 1608, he is of age to do any legal act on the morning of the 15th of February, 1629, though he may not have lived twenty-one years by nearly 48 hours. The reason assigned is that in law there is no fraction of a day; and if the birth were on the last second of one day and the act on the first second of the preceding day twenty-one years after, then twenty-one years would be complete; and in the law it is the same whether a thing is done upon one moment of the day or another." The same high authority (Sharswood) adds in a note of his own: "A person is of full age the day before the twenty-first anniversary of his birthday."
