Which was the birthday, according to Marcus Varro, of those born before the sixth hour of the night, or after it and in that connection, concerning the duration and limits of the days that are termed civil and are reckoned differently all over the world; and in addition, what Quintus Mucius wrote about that woman who claimed freedom from her husband's control illegally, because she had not taken account of the civil year.

IT is often inquired which day should be considered and called the birthday of those who are born in the third, the fourth, or any other hour of the night; that is, whether it is the day that preceded, or the day that followed, that night. Marcus Varro, in that book of his Human Antiquities which he wrote On Days, says: xiii. Frag. 2, Mirsch. Persons who are born during the twenty-four hours between one midnight and the next midnight are considered to have been born on one and the same day. From these words it appears that he so apportioned the reckoning of the days, that the birthday of one who is born after sunset, but before midnight, is the day after which that night began; but that, on the other hand, one who is born during the last six hours of the night is considered to have been born on the day which dawned after that night.
