America/Coyhaique: Chile’s Southern Patagonia Time Zone
America/Coyhaique is the IANA time zone identifier for the Chilean region of Aysén, anchored by the city of Coyhaique. It observes a fixed UTC offset of UTC-03:00 year-round, with no daylight saving time adjustments. This zone is used exclusively in Chile and shares its standard offset with numerous other zones across Argentina and Brazil.
Geographic Scope and Usage
America/Coyhaique applies to the Aysén del General Carlos Ibáñez del Campo Region in southern Chile, including the city of Coyhaique and surrounding areas such as Puerto Aysén and Chile Chico. It is one of several Chilean time zones; mainland Chile uses America/Santiago (which observes daylight saving), while Easter Island uses Pacific/Easter. The zone covers a sparsely populated but geographically significant part of Patagonia.
Offset and Abbreviation
The standard offset is UTC-03:00, commonly abbreviated as -03 (or CLST historically, but since no DST is observed, the abbreviation is simply -03 year-round). This offset places Coyhaique three hours behind Coordinated Universal Time. For example, when it is 12:00 UTC, local time in Coyhaique is 09:00.
No Daylight Saving Time
Unlike most of Chile, which shifts between CLT (UTC-04:00) in winter and CLST (UTC-03:00) in summer, America/Coyhaique remains at UTC-03:00 all year. This decision was made to align with the region’s high-latitude daylight patterns and to avoid the disruption of semi-annual clock changes. As a result, the offset is constant, and there is no spring-forward or fall-back rhythm.
Countries and Cities
The only country using America/Coyhaique is Chile. The anchor city is Coyhaique (population ~60,000), the capital of the Aysén Region. Other notable settlements include Puerto Aysén, Chile Chico, and Cochrane. The zone shares its standard offset with many zones in Argentina (e.g., America/Argentina/Buenos_Aires) and Brazil (America/Araguaina), making scheduling with these regions straightforward as they also use UTC-03:00 year-round (most of Argentina does not observe DST; Brazil’s DST was abolished in 2019).
Practical Guidance for Scheduling
For business and personal calls, America/Coyhaique is always three hours behind UTC. When coordinating with North America: Eastern Time (UTC-05:00 standard, UTC-04:00 DST) is 1-2 hours behind Coyhaique; Pacific Time (UTC-08:00 standard, UTC-07:00 DST) is 4-5 hours behind. With Europe: Central European Time (UTC+01:00 standard, UTC+02:00 DST) is 4-5 hours ahead. With neighboring Argentina (America/Argentina/Buenos_Aires, also UTC-03:00), there is no time difference. With mainland Chile (America/Santiago), note that Santiago observes DST: during southern summer (September to March), Santiago is at UTC-03:00 (same as Coyhaique); during winter (April to August), Santiago is at UTC-04:00 (one hour behind Coyhaique). Always check current DST status for Santiago.
Frequently Asked Questions
Does America/Coyhaique observe daylight saving time?
No. America/Coyhaique uses a fixed offset of UTC-03:00 all year. There are no clock changes.
What is the time difference between Coyhaique and New York?
New York is on Eastern Time. When New York is on standard time (EST, UTC-05:00), Coyhaique is 2 hours ahead. When New York is on daylight saving time (EDT, UTC-04:00), Coyhaique is 1 hour ahead.
Is America/Coyhaique the same as America/Santiago?
No. America/Santiago observes daylight saving time, shifting between UTC-04:00 (winter) and UTC-03:00 (summer). America/Coyhaique stays at UTC-03:00 year-round. During Santiago’s summer, they are the same; during winter, Coyhaique is one hour ahead.
Which other IANA zones share the same offset as America/Coyhaique?
Many zones in Argentina (e.g., America/Argentina/Buenos_Aires) and Brazil (e.g., America/Araguaina) also use UTC-03:00 year-round. However, some of those zones may have historical DST changes or different observance rules, so always verify current offsets.
What is the abbreviation for time in Coyhaique?
The standard abbreviation is -03, since no DST is observed. Historically, CLST was used during summer in Chile, but it is not applicable here.
Why does Coyhaique not change clocks like the rest of Chile?
The Aysén Region decided to remain on UTC-03:00 permanently to better match natural daylight hours at its high latitude and to avoid the disruption of semi-annual clock changes. This was implemented in 2015.
