Calculating the live gap…
A gap that narrows every summer
Buenos Aires and New York typically sit two hours apart, with Buenos Aires ahead. That gap narrows to one hour for roughly eight months of the year, whenever New York observes daylight saving time — Buenos Aires's own clock hasn't moved seasonally since Argentina abandoned DST after a brief 2007-2009 experiment.
Two major economies, a manageable gap
Buenos Aires is South America's second-largest metropolitan economy after São Paulo, and its one-to-two-hour gap with New York is comparatively easy to work around — considerably friendlier than the wider gaps New York shares with Asian or Pacific financial centers, and close enough that a Buenos Aires morning consistently overlaps with New York's morning and early afternoon.
A steady, predictable pairing
Because Buenos Aires's clock never moves, the entire seasonal variation in this pairing comes from New York's own daylight saving schedule — making the gap easy to predict once you know whether the US is currently observing DST.

Most of the standard workday is highlighted — Buenos Aires and New York share one of the wider, easier-to-manage overlap windows among cross-hemisphere pairings.
How we calculate this page: both live clocks, the current gap, the DST transition dates, and the hour-by-hour overlap table are all computed directly from the IANA America/Argentina/Buenos_Aires and America/New_York time zone data via your browser on every page load — nothing here is a fixed, hard-coded figure.
Frequently asked questions
What is the time difference between Buenos Aires and New York?
Usually two hours, with Buenos Aires ahead, narrowing to one hour while New York observes daylight saving time — Buenos Aires no longer shifts its own clock.
Does Buenos Aires observe daylight saving time?
No, not currently. Argentina experimented with DST intermittently for decades and most recently observed it from 2007 to 2009, before abandoning the practice; its clock has stayed fixed at UTC−3 since.
What is the best time to call between Buenos Aires and New York?
Roughly 9:00 a.m. to 3:00 p.m. in Buenos Aires overlaps with New York's business day for most of the year, covering the bulk of the standard workday on both sides.
Why does the Buenos Aires-New York gap narrow in summer?
New York observes daylight saving time from March to November, moving its clock forward an hour, which narrows the usual two-hour gap with fixed-clock Buenos Aires down to one hour for most of that stretch.
Is Buenos Aires's clock ahead of its solar time?
Somewhat, yes. Buenos Aires's longitude would suggest a UTC−4 solar time, but its fixed offset is UTC−3, adopted for practical and trade reasons rather than solar alignment.
How do I convert Buenos Aires time to New York time?
Subtract two hours most of the year, or one hour while New York observes daylight saving time (roughly March through November). For a guaranteed-accurate conversion on any specific date, use the time zone converter on WatchTime Online.
