Use this when you need to know whether a 2024-2028 UK date is a Monday-Friday working day after applying the official bank holidays for the selected division. 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 local council, school, employer, financial-market, emergency-closure or non-UK calendar, or a date outside 2024-2028. What it computes: Checks whether a date is a normal working day in England and Wales, Scotland or Northern Ireland using a pinned snapshot of the official GOV.UK bank-holiday feed. Example user requests: Is 28 December 2026 a working day in England and Wales, or the Boxing Day substitute holiday? | Is Scotland working on 15 June 2026? | Check whether 13 July 2026 is a working day in Northern Ireland. Inputs: date (date); division (enum, optional). Complete JSON argument examples: {"date":"2026-12-28","division":"england-and-wales"} | {"date":"2026-06-15","division":"scotland"} Outputs: date, weekday, division, division_name, is_working_day, day_type, bank_holiday_name, bank_holiday_notes, status_basis, source_url, licence, dataset_version, coverage_start, coverage_end, source_snapshot_sha256. Formula: official bank-holiday event → non-working; else Saturday/Sunday → non-working; else Monday-Friday → working Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/uk-working-day with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/everyday/uk-working-day.md
