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.

Frequently Asked Questions

How many business days are in December 2024 for Mexico?
December 2024 has 21 días hábiles under the Mexican federal holiday calendar. The month spans 31 calendar days, of which 9 fall on a weekend and 1 is a Mexican federal holiday that lands on a weekday. The remaining 21 weekdays are countable as días hábiles for invoicing, deadline tracking, and contract math.
Which Mexico holidays affect December 2024?
December 2024 contains one Mexican federal holiday: Navidad on Wednesday, December 25. Banks and Mexico financial markets close on each of these days. Regional or industry-specific closures may add further non-working days for narrower contract definitions; layer them into the calculator's Advanced options if needed.
Why are some Mexican holidays observed on Mondays and others on fixed dates?
The 2006 reform to Article 74 of the Ley Federal del Trabajo moved three holidays from fixed dates to Monday observance. Día de la Constitución (originally February 5) is now the first Monday of February. Natalicio de Benito Juárez (originally March 21) is now the third Monday of March. Día de la Revolución (originally November 20) is now the third Monday of November. Día de la Independencia (September 16), Día del Trabajo (May 1), and Navidad (December 25) remain on fixed dates regardless of weekday.
How is presidential transmission day handled here?
December 1 every six years is Día de la transmisión del Poder Ejecutivo Federal, when the new federal executive takes office. This is a labor holiday under Article 74, fraction VII of the LFT for that specific year only. The most recent transmission was December 1, 2024 (the start of Claudia Sheinbaum's term); the next is December 1, 2030. This calculator's Mexico data includes December 1 for transmission years and excludes it for non-transmission years, consistent with banking-sector practice.
Why does the business-day count vary year to year?
Two things shift the monthly count for Mexico. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Mexican federal holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. December 2023 also had 21 días hábiles, so working capacity is unchanged year over year.
