America/Guyana Time Zone Guide
The America/Guyana time zone covers the entire country of Guyana, located on the northeastern coast of South America. This zone uses a standard offset of UTC-04:00 year-round, with no daylight saving time adjustments. It is one of several Caribbean and South American zones at the same offset, making it easy to coordinate with neighboring regions.
Where and Who Uses America/Guyana
America/Guyana applies exclusively to Guyana, a country bordered by Venezuela, Brazil, Suriname, and the Atlantic Ocean. The zone is used by all residents and businesses within Guyana, including its capital, Georgetown. No other country or territory uses this specific IANA zone, though many others share the same UTC-04:00 offset.
Offset and Abbreviation
The standard offset is UTC-04:00, meaning local time is four hours behind Coordinated Universal Time. The common abbreviation for this time zone is GYT (Guyana Time). This offset is constant throughout the year, as Guyana does not observe daylight saving time.
Daylight Saving Time: None
Guyana has never observed daylight saving time in modern history. The country remains at UTC-04:00 all year, providing a stable time reference for scheduling. This eliminates the need for biannual clock changes and simplifies international coordination.

Practical Guidance for Scheduling
America/Guyana shares its offset with many Caribbean islands (e.g., Barbados, Curacao, Dominica) and parts of Brazil (e.g., Boa Vista, Cuiaba, Campo Grande) and Venezuela. For business hours overlap with North America: Eastern Time (UTC-05:00) is one hour behind Guyana, so 9 AM ET is 10 AM GYT. Central Time (UTC-06:00) is two hours behind. For Europe: London (UTC+00:00) is four hours ahead during winter, five hours ahead during British Summer Time. For example, 9 AM GYT is 2 PM London in winter, 1 PM in summer.
Historical Note
Guyana previously used UTC-03:45 (Guyana Mean Time) until 2015, when it switched to UTC-04:00 to align with neighboring countries. This change simplified trade and travel coordination.
