Use this when you need a federally regulated-employer general-holiday result for 2026-2027. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when you need a province/territory, municipal, private-employer, exchange or schedule-specific substitute-day calendar. What it computes: Checks a date against the 10 Canada Labour Code general holidays and the Canada Saturday/Sunday baseline; substitute days are not inferred. Example user requests: Is 2026-09-30 a Canada federal working day? Inputs: date (date). Complete JSON argument examples: {"date":"2026-09-30"} Outputs: territory, territory_name, weekday, is_working_day, day_type, holiday_names, holiday_observed, holiday_actual_dates, weekend_days, rest_day_policy, substitute_day_policy, calendar_scope, calendar_profile, dataset_version, sources. Formula: is_working_day = Canada weekday baseline and no Canada Labour Code general holiday Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/canada-federal-working-day with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/everyday/canada-federal-working-day.md
