The time difference between New York and Buenos Aires
The difference is not constant. In January Buenos Aires is 2 hours ahead New York; in July it is 1 hour ahead New York. The difference changes on Sunday, 8 March 2026 (from 2 hours ahead to 1 hour ahead) and Sunday, 1 November 2026 (from 1 hour ahead to 2 hours ahead) — those are the dates when one of the two cities changes its clocks and the other does not, or when they change on different days. Between those dates the difference is one value; outside them it is the other.
To convert a time, add the difference: 09:00 in New York is 11:00 in Buenos Aires in January and 10:00 in July; 17:00 in New York — the end of the working day — is 19:00 in Buenos Aires in January and 18:00 in July. To go the other way, subtract it: 09:00 in Buenos Aires is 07:00 in New York in January. The time difference calculator does the arithmetic for any date, and the UTC to Buenos Aires page gives the full conversion table for Buenos Aires.
Meeting overlap between New York and Buenos Aires

The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in New York and Buenos Aires
New York observes daylight saving: in 2026 the clocks go forward on 8 March 2026 and back on 1 November 2026, moving the offset from UTC−05:00 to UTC−04:00.
Buenos Aires does not observe daylight saving, so its offset of UTC−03:00 never changes.
The difference changes on Sunday, 8 March 2026 and Sunday, 1 November 2026 in 2026. On those dates, one city changes its clocks and the other does not — or they change on different days — so the difference moves by an hour. A standing meeting set in one city's local time will land an hour early or late on the other side until the second city catches up. The fix is to set the calendar event in UTC, or to check the overlap again after each change. The individual DST pages — New York DST 2026 and Buenos Aires DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in New York (11:00–19:00 in Buenos Aires). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
Calling and travel notes
When it is 09:00 in New York it is 11:00 in Buenos Aires in January; when it is 12:00 in New York it is 14:00 in Buenos Aires; when it is 17:00 in New York it is 19:00 in Buenos Aires. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling inside the Americas is usually straightforward: the difference between New York and Buenos Aires is small, and the working days overlap for most of the day. The main thing to check is daylight saving — not every place in the Americas observes it, and the ones that do change on different dates (the United States and Canada in March and November, Chile in September and April, Mexico not at all since 2022).

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in New York and time in Buenos Aires — explain each city's time zone, and the DST pages — New York DST 2026 and Buenos Aires DST 2026 — give the exact change dates.
