Philippines Working Day

Checks a date against the Saturday-Sunday weekend baseline and exact 2026-2027 authority events.

When to use

Do not use when: Local-government special holidays, employer schedules and 2027 Eid dates pending a separate proclamation are not inferred.

is_working_day = not an official Saturday/Sunday weekend date and no exact authority event
