Time now in Cuatro Vientos (Buenos Aires)

If you are coordinating from another country, the shortcut is the working window: a normal Cuatro Vientos (Buenos Aires) day of 09:00–17:00 falls between 15:00–23:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.

Sunrise today lands at 06:24 and sunset at 07:08 local time, giving 12h 44m of daylight. Those figures come from the city's own coordinates (22.43, -100.98) rather than a country-wide average, so they match what you would actually see from a window in Cuatro Vientos (Buenos Aires).

Clocks in Cuatro Vientos (Buenos Aires) stay put all year. There is no summer-time switch to remember, so UTC −6 is what you will get in January and in July alike — useful if you book recurring calls with people in Mexico.
