Buenos Aires is located at 34.60°S, 58.38°W. Its latitude determines how dramatically daylight hours change through the year.
The city uses the America/Argentina/Buenos_Aires timezone (GMT-3). It does not observe Daylight Saving Time, so solar times shift gradually through the year without abrupt clock changes.
Solar noon — the moment the sun reaches its highest point in the sky — occurs when the sun crosses the local meridian. In Buenos Aires this falls around 12:52 in mid-summer and 12:43 in December, reflecting UTC offset and any DST adjustments.
