When Asunción changes its clocks
Asunción is one of the places that still shifts its clocks twice a year
Asunción keeps Paraguay Standard Time at UTC-04:00 for most of the year, and moves to Paraguay Summer Time at UTC-03:00 during its southern-hemisphere summer. The shift is 1 hour.
Because Asunción is in the southern hemisphere, its summer time runs across the new year rather than through the middle of it. When northern cities move forward in March, Asunción is moving back — so the gap between Asunción and Europe or North America changes by two hours over the year, not one.
Next change
27 March 2027 — clocks move back by 1 hour, from UTC-03:00 to UTC-04:00.

Clock time versus solar time
Asunción's clock is unusually well matched to the sun: local noon falls within 9 minutes of the moment the sun is actually overhead. Most cities sit further out, because time zones follow borders rather than longitude.
During summer time that gap widens to 51 minutes ahead of the sun, which is the whole point of the exercise — shifting daylight into the evening.
