What Time Zone Is Jamaica In?
Jamaica uses a single timezone: the primary designation is America/New_York, which is currently UTC-05:00 from Coordinated Universal Time. The IANA Time Zone Database , the authoritative global reference used by operating systems, web services, and programming languages worldwide, lists this as America/New_York.
Regional Context
The Caribbean spans UTC-05:00 to UTC-04:00 with mixed DST observance. Cuba (UTC-05:00/UTC-04:00) observes DST. Puerto Rico, the US Virgin Islands, and the British Virgin Islands observe AST (UTC-04:00) year-round without DST. The Dominican Republic, Haiti, and Jamaica observe UTC-05:00 without DST. Barbados, Trinidad and Tobago, St. Lucia, and most eastern Caribbean islands observe AST (UTC-04:00) permanently. The Cayman Islands observe EST (UTC-05:00) without DST. Turks and Caicos moved to EST without DST in 2015, aligning with the US East Coast year-round. The result: within the Caribbean, some islands are offset from their neighbors by one hour depending on the season.
