  7. The period of time, within the limits of a natural day, set apart either by law or by common usage for the transaction of particular business or the performance of labor; as in banking, in laws regulating the hours of labor, in contracts for so many "days' work," and the like, the word "day" may signify six, eight, ten, or any number of hours. Fay v. Brown, 96 Wis. 434, 71 N.W. 895; McCulsky v. Klosterman, 20 Or. 108, 25 P. 366, 10 L.R.A. 785.

Monnin, 142 Ohio St. 113, 50 N.E.2d 310, 312; but that it is not divisible is a mere fiction, only observed for the purposes of justice and never adhered to when it would work mischief. Greulich v.
