These are the 18 public holidays in Colombia that land on a weekday in 2028 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 242 working days shown above are the 366 calendar days of 2028, minus the 106 Saturdays and Sundays, minus the 18 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 2028 that applies to 1 of Colombia's public holidays. At a standard eight-hour day, 242 working days works out to roughly 1,936 working hours across the year, before any annual leave is taken.
The Código Sustantivo del Trabajo article 161 sets the standard working week at 47 hours since 2023, reducing to 42 hours by 2026 under Law 2101 of 2021. The standard private-sector office and banking week is Monday to Friday at 8 to 9 hours, with retail and informal sectors operating Monday to Saturday. Sunday is the statutory weekly rest day under article 172. The Código General del Proceso article 118 rolls procedural deadlines falling on a non-working day to the next día hábil. Settlement of Colombian peso transactions runs on the Banco de la República's CUD RTGS system, which observes the eighteen national holidays.
Colombia has eighteen public holidays under Law 51 of 1983 (Ley Emiliani), the highest count in Latin America. The list combines Catholic dates (Epiphany, Saint Joseph's Day, Maundy Thursday, Good Friday, Ascension, Corpus Christi, Sacred Heart, Saints Peter and Paul, Assumption, All Saints', Immaculate Conception, Christmas Day) with civic dates (New Year's Day, Labour Day, Independence Day on 20 July, Battle of Boyacá on 7 August commemorating the 1819 decisive battle, Independence of Cartagena on 11 November, Day of the Races on 12 October). The Ley Emiliani specifically moved twelve of these to the following Monday to create three-day weekends, the most systematic Monday-isation regime in the Spanish-speaking world.
This matters because the working-day total is not spread evenly. Some months in Colombia 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 20.2 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 Colombia holiday calendar for 2028. 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 Colombia (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.
