About the time in Buenos Aires
If you are coordinating from another country, the shortcut is the working window: a normal Buenos Aires day of 09:00–17:00 falls between 16:00–00:00 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 05:57 and sunset at 06:44 local time, giving 12h 47m of daylight. Those figures come from the city's own coordinates (23.70, -109.70) rather than a country-wide average, so they match what you would actually see from a window in Buenos Aires.
The zone identifier America/Mazatlan is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Mazatlan keeps pointing at Mazatlan time whatever the date, which is why every timestamp on this page is built from it.
