Frequently asked questions
Common questions about COYHAI, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Is Coyhaique Time always UTC‑03:00?
- Yes. Since 2025 the Aysén Region has stayed on UTC‑03:00 all year, with no daylight saving changes.
- Has this region ever used daylight saving?
- Yes. Until 2024 the Aysén Region followed Chile’s national schedule, switching between UTC‑04:00 in winter and UTC‑03:00 in summer. In 2025 it chose to stay on UTC‑03:00 all year.
- Which cities use this time?
- The main reference city is Coyhaique in Chile’s Aysén Region, covering the long, scenic stretch near Patagonia’s northern end.
- Does Coyhaique Time match nearby zones like Santiago or Punta Arenas?
- Punta Arenas also stays on UTC‑03:00 all year, so it always matches. Santiago and most of Chile switch between UTC‑04:00 in winter and UTC‑03:00 in summer, so they match Coyhaique from September to April and are one hour behind from April to September.
- Why are there few references to this time in software?
- The Coyhaique zone was only added to the global time zone database in 2025, so devices and apps with outdated time zone data may not know it yet and may show Santiago’s time instead.
