## Purpose

Checks a date against the Saturday-Sunday weekend baseline and exact 2026-2026 authority events. Required calendar_scope and workweek distinguish national holidays from compensable public-sector days and five/six-day rosters.

**Use when:** You need a deterministic Peru Peru 2026 national_statutory result.

**Do not use when:** Choose calendar_scope and workweek explicitly. National holidays and public-sector compensable days have different applicability. This is a declared five-day (Saturday-Sunday rest) or six-day (Sunday rest) planning calendar, not proof of an individual's roster. Essential services, private-employer adoption, compensating shifts, regional holidays, banking, school, tax and procedural deadline calendars require separate evidence. The two compensable public-sector days remain working days for tax purposes. Later decrees require a new snapshot; dates beyond 2026 are unsupported.

## Example user requests

- Peru: National layer keeps July bridge open.
- Peru: Public-sector July bridge.
- Peru: Six-day Saturday.

## Limitations

Choose calendar_scope and workweek explicitly. National holidays and public-sector compensable days have different applicability. This is a declared five-day (Saturday-Sunday rest) or six-day (Sunday rest) planning calendar, not proof of an individual's roster. Essential services, private-employer adoption, compensating shifts, regional holidays, banking, school, tax and procedural deadline calendars require separate evidence. The two compensable public-sector days remain working days for tax purposes. Later decrees require a new snapshot; dates beyond 2026 are unsupported. Apply the explicitly selected weekly-rest model and the pinned national or public-sector date layer. Do not infer compensating shifts or tax deadlines. All values are computed from the formula above; no measurement or live data is involved.

## FAQ

**Is 27 July a national holiday?**

It is a compensable public-sector day under DS 075-2026-PCM. The national_statutory layer keeps it working when the selected weekly baseline permits.

**Does this calculate tax deadlines?**

No. The decrees keep the compensable days working for tax purposes. Use a separately verified tax calendar.
