These are the 9 public holidays in Mexico that land on a weekday in 2025 and therefore remove a working day. Holidays that fall on a weekend are not listed here because they do not change the working-day total.
The 252 working days shown above are the 365 calendar days of 2025, minus the 104 Saturdays and Sundays, minus the 9 public holidays that land on a weekday. Holidays that fall on a Saturday or Sunday are not subtracted, because they do not remove a day anyone would have worked; in 2025 that applies to 0 of Mexico's public holidays. At a standard eight-hour day, 252 working days works out to roughly 2,016 working hours across the year, before any annual leave is taken.
Article 69 of the Ley Federal del Trabajo requires one paid weekly rest day. The standard working week in offices and government is Monday to Friday, while retail and manufacturing often run Monday to Saturday. Article 71 entitles workers to a premium for weekend work. Civil procedure under article 286 of the Código Federal de Procedimientos Civiles treats día hábil as any day other than Saturday, Sunday and an official holiday. Settlement of Mexican peso transactions runs on the Sistema de Pagos Electrónicos Interbancarios operated by Banco de México, which uses the banking holiday list and not the labour holiday list, so the two diverge.
Mexico's Ley Federal del Trabajo article 74 lists seven días de descanso obligatorio: New Year's Day, the first Monday of February (Constitution Day), the third Monday of March (Benito Juárez's birthday), Labour Day, Independence Day on 16 September, the third Monday of November (Revolution Day) and Christmas Day. Each presidential inauguration on 1 October every six years is added when relevant. Religious observances such as Good Friday, Day of the Dead and Guadalupe Day are widely observed culturally and by many employers but are not statutory holidays. Banking holidays under the National Banking and Securities Commission add several additional dates that are not labour-law holidays, including Holy Thursday.
This matters because the working-day total is not spread evenly. Some months in Mexico carry several public holidays while others have none, so the month-by-month table above is the figure to use for payroll runs, billing cycles, SLA windows, and project plans rather than a flat assumption of about 21.0 working days per month. A month with two weekday holidays can have several fewer working days than a clear one, which changes capacity planning and the realistic delivery date for anything scheduled in business days.
To see the individual dates, the day of the week each holiday lands on, and the full official list, open the Mexico holiday calendar for 2025. You can subscribe to those dates as an .ics feed so they appear in your own calendar, or use the working-days-between-two-dates calculator to count business days for a specific date range rather than the whole year.
Working-day figures are computed from the public holiday list for Mexico (source: Nager.Date and the national references above) combined with a Monday-to-Friday business week. Regional holidays and substitute-day rules vary; confirm against the official calendar for legal or payroll use.
