When Antofagasta changes its clocks
Antofagasta is one of the places that still shifts its clocks twice a year
Antofagasta keeps Chile Standard Time at UTC-04:00 for most of the year, and moves to Chile Summer Time at UTC-03:00 during its southern-hemisphere summer. The shift is 1 hour.
Because Antofagasta 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, Antofagasta is moving back — so the gap between Antofagasta and Europe or North America changes by two hours over the year, not one.
Next change
3 April 2027 — clocks move back by 1 hour, from UTC-03:00 to UTC-04:00.
