Buenos Aires runs a busy festival calendar, from tango and book fairs to Pride and national holidays. This guide covers the events that recur reliably, with timing given as the month or period they usually fall in. Exact dates change every year, so check the official city tourism calendar before you book flights around any of them.
Major Annual Events
Tango BA Festival y Mundial
- When: late August into early September. The 2026 edition ran from 19 August to 2 September.
- What it is: a city-wide tango festival with classes, milongas, concerts and shows across dozens of venues and neighbourhoods, ending with the world championship finals. In 2026 the finals took place at Teatro Gran Rex.
- Good to know: entry to the festival programme is free, but some events need a reservation made a few days ahead and others are first come, first served. See our guide to milongas for the social dancing side.
Feria Internacional del Libro
- When: from late April into May. The 50th edition in 2026 ran from 23 April to 11 May.
- Where: La Rural exhibition grounds in Palermo, on Avenida Santa Fe.
- What it is: one of the largest book fairs in the Spanish-speaking world, with publisher stands, author talks and children’s programmes. A ticket is required.
Carnaval
- When: the days before Lent, usually February or early March. The two carnival days are public holidays.
- What it is: a neighbourhood celebration built around murga, the percussion-driven street theatre of Buenos Aires. It is smaller and more local than Rio’s version, and the best way to see it is at a barrio performance rather than a big parade.
Buenos Aires Pride
- When: the Marcha del Orgullo is held on the first Saturday of November, as part of a Pride week.
- Route: it starts at Plaza de Mayo, runs along Avenida de Mayo and ends at the Congreso.
- What it is: a large march with a daytime fair and music, one of the biggest Pride events in Latin America. Argentina legalised same-sex marriage in 2010, ahead of most of the region.
Holidays and Traditions
- Semana Santa (Holy Week): the week before Easter. Services take place at churches across the city. Good Friday is a public holiday and Holy Thursday is commonly a day off too, so it works as a long weekend. Book ahead and expect some businesses to close.
- 25 de Mayo (Revolucion de Mayo): a national holiday marking the start of the independence movement in 1810. The Plaza de Mayo and the Cabildo are the natural place to be.
- 9 de Julio (Independence Day): the national holiday for the 1816 declaration of independence in Tucuman. In the city it is mainly a day off, often spent over a family asado.
- Dia del Amigo (20 July): Argentina’s Friend’s Day, observed on 20 July. It is a social occasion rather than a public holiday, so expect restaurants and bars to be busy in the evening.
Christmas and New Year
Christmas falls in high summer, so celebrations centre on a late family dinner on the 24th, typically past midnight. Many shops and restaurants close on 24 and 25 December and 1 January, and the city is noticeably quiet. Weekend craft fairs such as the one at Plaza Francia in Recoleta continue through the season, and are good for gifts. For more on the holiday period, see our guide to Christmas in Buenos Aires.
Food and Wine Events
Buenos Aires has hosted large food fairs and a restaurant-week format in the past, but these have been irregular in recent years, and some have not run since before 2020. We do not list dates for them here. Check the city tourism events page for the current year’s food and wine programme before planning a trip around one.
Planning Around Events
- Book accommodation early for the tango festival period, the book fair and holiday weekends.
- Public holidays often come as long weekends, which fill buses, flights and day-trip destinations.
- Check the city’s official event pages the month before you travel for confirmed dates and ticket information.
