# add_ro_working_days

Use this when you need a deterministic Romania working-day offset. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when romania 2026 statutory holiday layer only, with required calendar_basis and work_schedule=mon_fri_planning. The basis selects dates, not a person's identity or religion. No union of Christian calendars, non-Christian additional holidays, public-sector bridge/recovery days, individual rosters, shift exceptions, bank/exchange/school opening, payroll or legal deadlines are computed. Other bases and future years are unsupported. What it computes: Adds or subtracts Romania authority-scope working days in exact coverage. Explicit calendar_basis and mon_fri_planning required; no union of calendars or personal roster inference. Example user requests: Add or subtract Romania working days around January 24 remains a statutory holiday even on Saturday. | Add or subtract Romania working days around Selected-calendar Good Friday. Inputs: start_date (date); working_days (integer); calendar_basis (enum); work_schedule (enum). Complete JSON argument examples: {"start_date":"2026-01-01","working_days":0,"calendar_basis":"romanian_orthodox","work_schedule":"mon_fri_planning"} | {"start_date":"2026-01-01","working_days":0,"calendar_basis":"roman_catholic","work_schedule":"mon_fri_planning"} Outputs: start_date, result_date, working_days_added, calendar_days_elapsed, public_holidays_skipped, territory, territory_name, day_type, holiday_names, holiday_kinds, holiday_details, calendar_scope, holiday_policy, substitute_day_policy, calendar_profile, dataset_version, sources, calendar_basis, work_schedule, is_statutory_holiday, payroll_scope, personal_roster_scope, additional_religious_holidays_scope. Formula: planning_workday = weekday AND no statutory holiday in the explicitly selected calendar_basis Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/romania-public-add-working-days with the same JSON input fields.
