Checks a date against the Saturday-Sunday weekend baseline and exact 2026-2026 authority events.

When to use

You need a deterministic Brazil Brazil federal executive public administration (SIPEC) result.

Do not use when: This is not a universal Brazilian private-employer calendar; state, municipal, sector, employer and private payroll schedules are not inferred.
