- Canonical page: https://tttkmbb.com/everyday/norway-public-add-working-days · This document: https://tttkmbb.com/everyday/norway-public-add-working-days.md · JSON definition: https://tttkmbb.com/everyday/norway-public-add-working-days.json

## Purpose

Adds or subtracts Norway authority-scope working days in exact coverage.

**Use when:** You need a deterministic Norway working-day offset.

**Do not use when:** Nationwide statutory full-day list only. Christmas Eve, Easter Eve, Whit Eve, New Year's Eve, collective-agreement, employer, sector, school, bank and local closures are not inferred. Norwegian annual-leave law treats Saturdays separately from Sundays and public holidays; this package uses the declared Monday-Friday business baseline.

## Example user requests

- Add or subtract Norway working days around Constitution Day.
- Add or subtract Norway working days around Christmas Eve is not a full-day statutory holiday.

## Limitations

Nationwide statutory full-day list only. Christmas Eve, Easter Eve, Whit Eve, New Year's Eve, collective-agreement, employer, sector, school, bank and local closures are not inferred. Norwegian annual-leave law treats Saturdays separately from Sundays and public holidays; this package uses the declared Monday-Friday business baseline. Skip Saturday/Sunday and exact pinned authority events; do not add unverified substitute days. All values are computed from the formula above; no measurement or live data is involved.

## FAQ

**Are Christmas Eve, Easter Eve, Whit Eve or New Year's Eve nationwide full-day statutory holidays?**

No. They may be covered by agreements, sector rules or partial-day arrangements, but this package does not infer them as nationwide full-day statutory holidays.
