Inconsistent definition of “work days” vs. weekday-only counting

[edunzer]

countUsableWorkdays only counts Mon–Fri via isWeekday, but createScheduleException applies hours across up to 7 days based on input.numberOfWorkDays. If numberOfWorkDays includes weekends (6 or 7), your hours-per-day calculation is based on weekday-only counts, but exceptions may allocate hours to weekends too → misallocation.

How to fix: Align day counting with numberOfWorkDays:

• If workDays <= 5, count only Mon–Fri.
• If workDays == 6, count Mon–Sat.
• If workDays == 7, count all days.
  You can implement an isWorkingDay(Date d, Integer workDays) helper and use it both for counting and splitting.
