Add Hungary Working Days

Adds or subtracts Hungary authority-scope working days in exact coverage. Requires an explicit general Monday-Friday work schedule; includes three working Saturdays and paired rest dates.

When to use

You need a deterministic Hungary working-day offset.

Do not use when: Hungary 2026 general Monday-Friday work schedule only (Labour Code section 97(2), NGM 10/2025). Requires explicit work_schedule. Eleven statutory holidays and three paired transfers are included; three Saturdays are working. No shift, personal, bank, exchange, school, local-office opening or payroll schedule is inferred. No automatic substitute Monday. The annual decree expires 2027-01-01; later schedules require new evidence.

Formula

working = published makeup day OR (weekday AND not statutory holiday AND not transferred rest)

FAQ

Which work schedule is covered?

Only the general Monday-Friday schedule explicitly selected by the caller. Shift or institution-specific opening hours are outside scope.

Is August 15 a working Saturday?

No. The final decree uses August 8; an earlier proposed August 15 must not replace it.
