(b) Workday means those hours which comprise in sequence the employee's regular daily toor of duty within any 24-hour period, whether falling entirely within one calendar day or not.
Sec. 3. (a) Any employee whose basic workweek does not include Sunday and who would ordinarily be excused from work on a holiday falling within his basic workweek shall be excused from work on the next workday of his basic workweek whenever a holiday falls on Sunday.
(b) Any employee whose basic workweek includes Sunday and who would ordinarily be excused from work on a holiday falling within his basic workweek shall be excused from work on the next workday of his basic workweek whenever a holiday falls on a day that has been administratively scheduled as his regular weekly nonworkday in lieu of Sunday.
Sec. 4. The holiday for a full-time employee for whom the head of a department has established the first 40 hours of duty performed within a period of not more than six days of the administrative workweek as his basic workweek because of the impracticability of prescribing a regular schedule of definite hours of duty for each workday, shall be determined as follows:
(a) If a holiday occurs on Sunday, the head of the department shall designate in advance either Sunday or Monday as the employee's holiday and the employee's basic 40-hour tour of duty shall be deemed to include eight hours on the day designated as the employee's holiday.
(b) If a holiday occurs on Saturday, the head of the department shall designate in advance either the Saturday or the preceding Friday as the employee's holiday and the employee's basic 40-hour tour of duty shall be deemed to include eight hours on the day designated as the employee's holiday.
(c) If a holiday occurs on any other day of the week, that day shall be the employee's holiday, and the employee's basic 40-hour tour of duty shall be deemed to include eight hours on that day.
(d) When a holiday is less than a full day, proportionate credit will be given under paragraph (a), (b), or (c) of this section.
Sec. 5. Any employee whose workday covers portions of two calendar days and who would, except for this section, ordinarily be excused from work scheduled for the hours of any calendar day on which a holiday falls, shall instead be excused from work on his entire workday which commences on any such calendar day.
Sec. 6. In administering the provisions of law relating to pay and leave of absence, the workdays referred to in sections 3, 4, and 5 shall be treated as holidays in lieu of the corresponding calendar holidays.
