Regional calendars
Holiday dates are only useful when they match the calendar your employer follows. These regional pages pair government sources with the same calendar logic used by Holiday Optimizer, then show what 10, 15, or 20 PTO days can produce.
Every state is covered with official sources, state-specific differences, and generated PTO results. Washington, D.C. is included separately.

New South Wales has a state-specific public-holiday calendar. Easter creates a four-day block, Monday holidays create easy long weekends, and the additional Anzac Day public holidays in 2026 and 2027 create an extra planning opportunity.
