Here's the exact time right now, sunrise/sunset, moon phase, and how it compares to your own clock.

The policy was quietly dropped after 2009 and has not returned since — Buenos Aires has kept a single, unchanging UTC−3 offset every day of the year for well over a decade. ## A clock that already runs ahead of the sun Buenos Aires sits at roughly 58.4°W longitude, a position that would put it closer to a UTC−4 solar time zone. Its fixed UTC−3 clock — adopted for practical and economic reasons tied to trade and administrative convenience rather than any wartime alignment — means the city's official time already runs somewhat ahead of the sun, even without daylight saving layered on top. It's a milder version of the mismatch that pushes Madrid's clock an hour ahead of its solar time, though Buenos Aires's story is about economic convenience and abandoned energy policy rather than a historical alignment with another country. **Trivia:** Brazil, Argentina's neighbor and the subject of another page on this site, also abandoned daylight saving time — São Paulo's DST ended in 2019 — making fixed, unchanging clocks the norm across much of South America's largest economies today. ## Time differences from Buenos Aires Because Buenos Aires's own clock never moves, every gap below shifts only when the other city changes its own DST. | City | Typical difference | Notes | | --- | --- | --- | | São Paulo | Same time | Neither city observes DST | | New York | Buenos Aires +2h (+1h in EDT) | New York observes seasonal DST | | London | Buenos Aires −4h (−3h during UK's winter GMT) | UK observes seasonal DST on the opposite calendar half | | Mexico City | Buenos Aires +3h | Mexico City fixed, no DST either | | Dubai | Buenos Aires −7h | Dubai has no DST — a fixed gap | São Paulo is the simplest comparison — both South American cities keep a fixed offset with no daylight saving, so their clocks always agree exactly. ## Working hours and when to call Buenos Aires keeps a standard 9:00–18:00 business day, with many offices starting later and lunch breaks running long. - **From São Paulo or Mexico City:** comfortable overlap most of the day. - **From New York:** a Buenos Aires morning call lands mid-to-late morning in New York. - **From London:** a Buenos Aires morning call lands early afternoon in London. ## Daylight through the year At roughly 34.6°S, Buenos Aires is in the Southern Hemisphere, so its seasons run opposite the Northern Hemisphere cities on this site — about 14 hours of daylight around the December solstice (Southern Hemisphere summer), narrowing to about 9 hours 50 minutes around the June solstice (Southern Hemisphere winter). **How we calculate this page:** the live clock, UTC offset, and DST dates above are read directly from the IANA America/Argentina/Buenos\_Aires time zone data via your browser, not hard-coded. Sunrise, sunset, solar noon, and twilight times are computed from Buenos Aires's exact coordinates (34.6037°S, 58.3816°W) using standard solar position formulas, recalculated on every page load. Moon phase is derived from the current synodic month. Airport distance uses the great-circle formula from those same coordinates to each airport's published location. ## Frequently asked questions ### What time zone does Buenos Aires use? Argentina Time (ART, UTC−3), identified as America/Argentina/Buenos\_Aires, fixed year-round with no daylight saving time. ### Does Argentina observe daylight saving time? No, not currently. Argentina experimented with DST intermittently for decades and most recently observed it from 2007 to 2009 as an energy-saving measure, before quietly abandoning the practice. ### Why did Argentina adopt daylight saving time in 2007? The government reintroduced DST during a period of electricity shortages, aiming to reduce peak evening demand by shifting clocks forward each spring; the policy lasted through 2009 and was then dropped. ### Is Buenos Aires's clock ahead of its solar time? Somewhat, yes. Buenos Aires sits at a longitude that would suggest a UTC−4 solar time, but its fixed offset is UTC−3, adopted for practical and trade reasons rather than solar alignment. ### What is the time difference between Buenos Aires and New York? Typically 2 hours, with Buenos Aires ahead, narrowing to 1 hour while New York observes daylight saving time. ### What are normal business hours in Buenos Aires? Most offices run roughly 9:00 a.m. to 6:00 p.m., often with a later start and an extended midday break. ### How do I convert Buenos Aires time to my own time zone? Use the [time zone converter](https://watchtimeonline.com/tools/time-zone-converter.html), selecting Buenos Aires as the source zone and checking a specific date if the other zone observes DST. ### Is Buenos Aires on the same time as São Paulo? Yes. Both cities keep a fixed offset with no daylight saving time, so their clocks always agree exactly. ### Why is Buenos Aires's daylight pattern opposite to cities like New York or London? Buenos Aires is in the Southern Hemisphere, so its seasons run opposite those of Northern Hemisphere cities — summer around December, winter around June. ## Compare with other cities [São PauloBrazil](https://watchtimeonline.com/tools/city/sao-paulo.html) [Mexico CityMexico](https://watchtimeonline.com/tools/city/mexico-city.html) [New YorkUnited States](https://watchtimeonline.com/tools/city/new-york.html) [LondonUnited Kingdom](https://watchtimeonline.com/tools/city/london.html) Planning a call across time zones?
