How to adjust this baseline
Start with the weekday total on this page, then subtract any non-working holidays that apply to your location or organization. A single local holiday reduces the displayed baseline by one day; a half-day closure is better tracked as an hours adjustment.
Keep calendar days, standard weekdays, and organization-specific working days separate so payroll, billing, project capacity, and school schedules do not mix universal calendar math with local policy choices.
