Mexico reporting cycles and business-day rules
Mexican business-day cycles align with SAT declaración mensual deadlines on the 17th of the following month, IMSS cuotas obreras and INFONAVIT bimonthly contributions, and CFDI 4.0 invoice issuance against the buyer's pago timeline. Banxico operates SPEI as a near-real-time interbank clearing system; bank cutoffs typically run to 18:00 local time. The 2006 reform under the Ley Federal del Trabajo moved Día de la Constitución, Natalicio de Benito Juárez, and Día de la Revolución to Mondays, producing predictable three-day weekends. Article 74 governs the seven mandatory federal labor holidays.
