[PAULUS libro tertio decimo ad Sabinum. ] §2.12.8.prMore Romano dies a media nocte incipit et sequentis noctis media parte finitur.
[PAULUS, On Sabinus, book 13] According to Roman custom, a day begins at midnight and ends at the middle part of the following night.
itaque quidquid in his niginti quattuor horis, id est duabus dimidiatis noctibus et luce media, actum est, perinde est, quasi quauis hora lucis actum esset.
Therefore, whatever has been done in these twenty-four hours, that is, in two halved nights and the intervening daylight, is just as if it had been done at any hour of the day.
