Notes of Decisions

Week

Because a week begins on Sunday and the legal holiday was on Monday, the first day of the week as that term is defined in the Law is not a customary vacation period although it is a customary day off for working people. Therefore, school bus drivers seeking unemployment compensation were not excluded from coverage for a week in which Monday was a holiday and the remainder of the week was snow days under 43 P. S. § 802.1. North Penn Sch. Dist. v. Unemployment Compensation Board of Review, 662 A.2d 1161 (Pa. Cmwlth. 1995).
