CLT
Chile Standard Time
Chile Standard Time follows the pulse of Santiago, stretching from the Andes to the Pacific coast. This single-country region shifts between UTC−03:00 and UTC−04:00 as daylight saving time rolls through southern-hemisphere seasons, so local clocks spring forward and fall back in step with Chile’s long summer evenings and crisp mountain mornings.

IANA zones · the technical identifiers
The zone that resolve to CLT.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about CLT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Which time zone code covers Chile?
- Everything in Chile runs on Chile Standard Time (CLT), which covers all of the country’s clocks under a single representative zone: America/Santiago.
- How does daylight saving work in Chile?
- Chile toggles between standard time at UTC−04:00 and daylight time at UTC−03:00. When DST is active, clocks across Chile move one hour ahead to stretch evening daylight during the southern summer months.
- Is mainland Chile ever on the same offset year-round?
- No. The entire mainland region joins the DST change. Today Chile sits at UTC−04:00, but next spring most of the country will be on UTC−03:00.
- Which upcoming shift should I watch for?
- The next DST transition falls on 6 September 2026 at 01:00 local time, when clocks across Chile roll back from UTC−03:00 to UTC−04:00.
- Do any Chilean territories keep a different offset?
- Within the CLT region (America/Santiago) mainland Chile shares the same offset and DST schedule; all clocks here stay in sync under one representative zone.
- What’s unique about living with Chile’s time shifts?
- Because daylight saving tracks the southern-hemisphere seasons, Chile’s clock changes feel reversed compared to northern regions—summer evenings glow later, while winter days start bright and early at UTC−04:00.
- Are all member zones in DST right now?
- No. The region is currently on standard time at UTC−04:00; DST will return next September when clocks spring forward.
- Does CLT affect cross-border coordination?
- Yes. As the entire country flips together, partners in neighboring time zones need to watch for the September transition to stay aligned with Chile’s shifting calendars and schedules.
