Buenos Aires never changes its clocks
Buenos Aires stays on UTC-03:00 all year round. This is worth being careful about rather than relaxed about: the gap between Buenos Aires and a city that does observe daylight saving still moves twice a year, because the other end moved. A recurring call can drift by an hour without anything changing here at all.
Time difference from Buenos Aires
Where a range is shown, the gap genuinely changes during the year. That is not rounding or hedging — it is two governments moving their clocks on different weekends.

Daylight in Buenos Aires through the year
From about 9.8 hours in June to 14.5 hours in December. This is the part a plain clock leaves out: 17:00 is a bright evening in one month and long dark in another.

Daylight length is accurate. The clock times of sunrise and sunset assume each city sits at the centre of its time zone, which can put them up to about an hour and a quarter out for places near a zone's edge — Madrid being the standard example. Day length is unaffected.
Questions
About time in Buenos Aires
What time zone is Buenos Aires in?
Buenos Aires uses the IANA time zone America/Argentina/Buenos_Aires, a fixed UTC-03:00 with no daylight saving.
Does Buenos Aires observe daylight saving time?
No. Buenos Aires stays on UTC-03:00 all year. That does not mean the gap between Buenos Aires and other cities is fixed, though: when a city that does observe daylight saving changes its clocks, the difference between you and them moves even though nothing changed here.
Why does the time difference to Buenos Aires keep changing?
Because the two places do not change their clocks on the same weekend, and in opposite hemispheres they change in opposite directions. London is a clear example: it sits 3 hours ahead, then 4 hours ahead across the year rather than one fixed distance.
How much daylight does Buenos Aires get?
Around 14.5 hours at the longest, in December, and about 9.8 hours at the shortest, in June. The table on this page lists sunrise and sunset through the year. Times are calculated from Buenos Aires's latitude of -34.60° and are approximate to within about an hour for cities that sit well away from the centre of their time zone.
