Luxembourg Working Day

Checks a date against the Saturday-Sunday weekend baseline and exact 2026-2028 authority events. Requires explicit mon_fri_planning; personal compensatory leave and bank-only closures are not computed.

When to use

You need a deterministic Luxembourg Luxembourg 2026-2028 eleven annual statutory holidays with explicit Monday-Friday planning baseline before individualized leave result.

Do not use when: Luxembourg 2026-2028 statutory holiday dates over an explicitly selected Monday-Friday planning baseline, BEFORE individual annual or compensatory leave. A holiday on a normally non-worked day may produce compensatory leave depending on the employee's schedule, hours and applicable rules; no compensation date or next-Monday closure is assigned here. Bank-only Good Friday/Christmas Eve afternoon, customary or collectively agreed holidays, school/local/employer/shift schedules, hours, payroll, personal entitlements and legal deadlines are not computed.

Example user requests

Formula

planning_workday = weekday AND no statutory_holiday_rest; individual leave is not deducted

FAQ

Is the Monday after a weekend holiday automatically off?

No uniform next-Monday date is assigned by this package. Compensatory leave can depend on the person's normal work schedule and must be arranged under applicable rules; this tool neither denies nor computes that entitlement.

Does the annual working-day count include my compensatory leave?

No. It is a Monday-Friday calendar count before personal annual leave, compensatory leave and employer/collective arrangements. Do not use it as actual annual attendance or payroll.

Are Good Friday, All Souls or Christmas Eve statutory days off?

They are not among the eleven general statutory holidays. Bank, collective, customary or employer arrangements may differ and are outside this profile.

What makes the data reproducible?

Pinned official CC0 JSON dates in four languages are cross-checked with the ITM French year table. Source URLs, retrieval times, SHA-256 hashes, coverage and limitations accompany results.
