Does Argentina use daylight saving time?

No. Argentina last changed its clocks in the 2008–2009 summer and has stayed on UTC−3 ever since.

What time is a 7:30 PM Inter Miami game in Buenos Aires?

8:30 PM in Buenos Aires while the US is on daylight time, and 9:30 PM in February and early March before the US clocks change.

Why is Buenos Aires on UTC−3 when it lies further west?

Argentina chose UTC−3 to keep long summer evenings and share a clock with Brazil and Uruguay. The trade-off is late, dark winter mornings.

A clock set ahead of the sun

Argentina Time is UTC−3 all year. The country last used daylight saving in the 2008–2009 summer and has not changed its clocks since. Geographically, Buenos Aires sits closer to UTC−4, and western provinces such as Mendoza closer to UTC−5, so Argentina effectively lives on permanent summer time: sunsets come late, past 8:00 PM in December, and dinner at 9:30 or 10:00 PM is normal.

Because Argentina is in the Southern Hemisphere, its holiday season is the opposite of New York's. January is high summer, many families leave for the coast, and business slows down until February. Plan launches and contract negotiations with Argentine partners around that.

Software teams and football in the same day

Argentina is one of Latin America's strongest software exporters; Globant and Mercado Libre were both founded in Buenos Aires, and thousands of Argentine developers work for US companies. A New York day from 9:00 AM to 5:00 PM is 11:00 AM to 7:00 PM in Buenos Aires in winter and 10:00 AM to 6:00 PM in summer, close to a full shared day.

Since Lionel Messi joined Inter Miami in 2023, Argentines also follow Major League Soccer on Eastern time. A 7:30 PM kickoff in Miami is 8:30 PM in Buenos Aires during most of the season, which runs mainly through the US daylight-time months, and 9:30 PM in February and early March. São Paulo shares the same offset, so the Brazil to Eastern time page gives identical numbers.
