About the time in Buenos Aires
The zone identifier America/Mexico_City is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Mexico_City keeps pointing at Mexico City time whatever the date, which is why every timestamp on this page is built from it.
Buenos Aires sits at latitude 16.21, in the tropical band, so day length here swings only a little between midwinter and midsummer — today's 12h 36m is one point on that curve, not a fixed value.
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 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.
