Use this when you need a deterministic Bangladesh Bangladesh 2026 government public-office holiday schedule plus later election-period national closures result. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when government/public-office schedule only; private-employer, bank, school, industrial-zone, essential-service, regional hill-district, optional-religious and later unlisted ad hoc schedules are not inferred. February 10 is not included because the reported later holiday was industrial-zone specific. Lunar dates may be revised by a later official notice. What it computes: Checks a date against the Friday-Saturday weekend baseline and exact 2026-2026 authority events. Example user requests: Bangladesh: Election-period special holiday. | Bangladesh: Eid-ul-Adha period. Inputs: date (date). Complete JSON argument examples: {"date":"2026-02-11"} | {"date":"2026-05-31"} Outputs: territory, territory_name, weekday, is_working_day, day_type, holiday_names, holiday_kinds, holiday_details, calendar_scope, holiday_policy, substitute_day_policy, calendar_profile, dataset_version, sources. Formula: is_working_day = not an official Friday/Saturday weekend date and no exact authority event Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/bangladesh-public-working-day with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/everyday/bangladesh-public-working-day.md
