What are the Días de Descanso Obligatorio?

These are the mandatory rest days set by Article 74 of the Ley Federal del Trabajo. There are seven recurring ones each year plus a presidential transition day every six years. Employers must give these days off or pay a premium for working them.

Why are some holidays on a Monday rather than their historical date?

A 2006 reform moved Constitution Day, Benito Juárez Day, and Revolution Day to the first Monday of February, third Monday of March, and third Monday of November respectively, to create long weekends. The tool applies the Monday dates, not the original fixed dates.

What is the presidential transition day?

When the federal executive power is handed over, that day is an obligatory rest day. From the 2024 cycle the handover is 1 October; in earlier six-year cycles it fell on 1 December. The tool adds it only in handover years.

What are the 5 non-obligatory days?

These are widely recognised civic dates that are not mandatory rest days: the original 5 February and 21 March dates, Cinco de Mayo, Día de Muertos on 2 November, and the original 20 November. Use the checkbox if your workplace observes them.

Does this calculate prima vacacional or overtime pay?

No. It counts working versus rest days only. Premium pay for working an obligatory day, and the prima vacacional vacation bonus, are separate payroll calculations that build on top of this working-day count.

Mexico Public Holiday Counter

In Mexico the mandatory rest days come from Article 74 of the Ley Federal del Trabajo, and three of them move to a Monday each year. This counter applies the correct obligatory days — including the six-yearly presidential transition — so a date range gives the true number of working days for payroll and scheduling.

How it works

For each year the tool builds the obligatory rest-day set, optionally adds the five civic days, then walks the range:

fixed obligatory  : 1 Jan, 1 May, 16 Sep, 25 Dec
moving Mondays    : Constitution (1st Mon Feb), Benito Juarez (3rd Mon Mar),
                    Revolution (3rd Mon Nov)
transition day    : 1 Oct in handover years (1 Dec in pre-2024 cycles)
optional civic    : 5 Feb, 21 Mar, 5 May, 2 Nov, 20 Nov (only if enabled)
working day       = Mon-Fri AND not in the applied holiday set

Example and notes

Because Constitution Day is the first Monday of February rather than the fifth, a range covering early February in different years lands on different dates — let the tool compute it. The presidential transition day is easy to forget: it only appears once every six years, so a 2024 range that crosses 1 October will show one extra obligatory day that a 2025 range will not. The non-obligatory civic days are off by default because they are not legally guaranteed days off.
