When San Lorenzo changes its clocks
San Lorenzo is one of the places that still shifts its clocks twice a year
San Lorenzo 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 San Lorenzo 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, San Lorenzo is moving back — so the gap between San Lorenzo 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
San Lorenzo's clock is unusually well matched to the sun: local noon falls within 10 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 50 minutes ahead of the sun, which is the whole point of the exercise — shifting daylight into the evening.
