Mexico Working Day

Checks a date against the Saturday-Sunday weekend baseline and exact 2026-2027 authority events.

When to use

You need a deterministic Mexico Mexico Federal Labour Law mandatory rest days result.

Do not use when: Article 69 weekly rest is at least one day after six days and the employer/worker schedule is not inferred; sector, state, employer, school and bank calendars are outside scope.

Example user requests

Mexico: Constitution Day observed.

Formula

is_working_day = not an official Saturday/Sunday weekend date and no exact authority event

FAQ

Does this infer each employee's weekly rest day?

No. Article 69 requires at least one rest day in six and Article 70 leaves continuous schedules to employer/worker arrangements; only Article 74 statutory rest dates are returned.
