Día de la Memoria
Held on March 24 (the date a military coup took over the Argentine government in 1976), this public holiday commemorates the victims of Argentina's military dictatorship. Over seven years, tens of thousands of people 'disappeared' and were never heard from again.
January is peak summer in Argentina. Porteños (residents of Buenos Aires) escape the sweltering heat at beach resorts, making them crowded and expensive. It’s also high season in Patagonia, so expect top prices there, too.
Festival Nacional del Folklore
Near the city of Córdoba, the town of Cosquín hosts the National Festival of Folk Music during the last week of January. It’s the country’s largest and best-known folklórico (folk music) festival.
Previously called the Paris–Dakar Rally, this 9000km all-terrain race (www.dakar.com) has now been run in South America since 2009. Both amateurs and professional racers complete in this endurance classic.
Summertime crowds at the beaches and in Patagonia thin later in the month. The Andean deserts and the Iguazú region continue to be very hot, but the Lake District is ideal. Mendoza’s grape harvest begins.
Festival Nacional del Lúpulo
El Bolsón's hop festival honors the key ingredient for its artisanal craft beers. Expect musical performances, activities, food and plenty of beer tasting (of course).
Autumn is starting and Buenos Aires is balmy, though rainy. Prices fall at the beaches and in Patagonia, but the weather remains decent. The north starts cooling, and Iguazú Falls is less hot and humid.
Fiesta Nacional de la Vendimia
Mendoza city’s week-long Fiesta Nacional de la Vendimia kicks off with parades, folklórico events and a royal coronation – all in honor of Mendoza’s wines.
Lake District forests start changing from verdant green to fiery hues. Patagonia is clearing out but you might get lucky with decent hiking weather. Buenos Aires heads into low season, with still-pleasant temperatures.
Festival Nacional del Chocolate
Happening during Easter week (dates vary annually), Bariloche's chocolate festival often highlights a 9m tall chocolate egg, cracked and consumed on Easter Sunday. Look for the world's longest chocolate bar, too.
Festival Internacional de Cine Independiente
Independent film buffs shouldn’t miss this festival in Buenos Aires, which screens more than 100 films from Argentina and Uruguay.
It’s late autumn and Buenos Aires is cool as the rains ebb. It’s a good time to visit Iguazú Falls. The crowds also leave Mendoza, though vineyards are still a gorgeous red from autumn leaves.
Día de Virgen de Luján
On May 8 thousands of devout believers make a 65km pilgrimage to the pampas town of Luján in honor of the Virgin Mary. Other pilgrimages take place in early October, early August, late September and on December 8.
Winter begins. Beach resorts and Patagonia close down, but it’s an ideal time to visit the deserts of the Andean Northwest and Iguazú Falls, which have less rain and heat at this time of year.
Fiesta de la Noche Más Larga
Ushuaia celebrates the longest night of the year with about 10 days' worth of music and shows.
Anniversary of Carlos Gardel’s death
On June 24, 1935, tango legend Carlos Gardel died in a plane crash in Colombia. Head to Buenos Aires’ Chacarita cemetery to see fans pay their respects at his grave and statue.
Ski season is at its peak, so skiers head off to the resorts around Bariloche, San Martín de los Andes and Mendoza. Whale-watching season starts heating up in the area around Península Valdés.
Día de la Independencia
Argentina's Independence Day is July 9, and celebrations are especially strong in Tucumán, where the country's independence was first declared.
Beach resort towns are dead and Patagonia is desolate and cold. Buenos Aires is still cool, but it’s a great time to explore the theaters, museums and art galleries.
Tango BA Festival y Mundial
World-class national and international tango dancers perform throughout Buenos Aires during this two-week festival. It's a great way to see some of the country's best tango dancers and musicians do their thing.
Spring has sprung, and it’s peak season for whale watching (both southern right whales and orcas) around Península Valdés. Polo season begins in Buenos Aires and the ski slopes wind down.
Vinos y Bodegas
Lovers of the grape shouldn’t miss this huge Buenos Aires event, which highlights vintages from bodegas (wineries) all over Argentina.
It’s a fine time to visit Buenos Aires and central Argentina. The season is just starting in Patagonia, but the crowds haven’t quite descended. Flowers are blooming in the Lake District.
Join the swillers and oompah bands at Argentina’s national beer festival, Villa General Belgrano’s Oktoberfest in the Central Sierras.
Bariloche a la Carta
This week-long food festival represents the Lake District’s best culinary offerings. Dozens of restaurants take part, showcasing special menus, and numerous food stalls and microbreweries set up shop in the main square.
Buenos Aires' weather is perfect, its jacaranda trees dazzling with purple blooms. It’s a good time to visit the beach resorts and Patagonia, since the crowds and peak prices are still some weeks away.
Fiesta de la Tradición
Summer begins and it’s excellent beach weather at the resorts (just before the January peak). It’s also ideal weather for outdoor activities in the Lake District, and penguin and hiking seasons start in Patagonia.
