# add_mt_working_days Use this when you need a deterministic Malta 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 malta 2026 named statutory holidays and Sunday public-holiday status over an explicitly selected Monday-Friday planning baseline BEFORE individual annual or compensatory leave. Additional vacation entitlement for a named holiday on a weekly rest day depends on the person's employment and roster; no next-Monday or later leave date is assigned. Bank-only, school, local, employer and shift calendars, hours, payroll, personal entitlements and legal deadlines are not computed. Future years require a separately verified package. What it computes: Adds or subtracts Malta authority-scope working days in exact coverage. Required mon_fri_planning; named holidays and Sunday statutory status remain distinct. Personal leave and bank-only dates are not computed. Example user requests: Add or subtract Malta working days around Good Friday is scheduled public rest. | Add or subtract Malta working days around Ordinary Sunday is public holiday, not a named holiday. | Add or subtract Malta working days around No invented Monday compensation. Inputs: start_date (date); working_days (integer); work_schedule (enum). Complete JSON argument examples: {"start_date":"2026-01-01","working_days":0,"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, work_schedule, is_public_holiday, is_named_statutory_holiday, is_national_holiday, is_other_scheduled_public_holiday, is_sunday_public_holiday, holiday_on_baseline_weekend, sunday_legal_basis, compensatory_leave_scope, personal_roster_scope, payroll_scope, compensatory_date_policy. Formula: planning_workday = Monday_to_Friday AND no named statutory holiday; individual leave is not deducted Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/malta-public-add-working-days with the same JSON input fields.
