Cockburn Town on Grand Turk island is the capital of the Turks and Caicos Islands, a British Overseas Territory in the Caribbean. For most of its history the islands used Eastern Time with DST, keeping the same schedule as the US East Coast. [3]

In 2015, the islands switched to Atlantic Standard Time (UTC-4, no DST), abolishing daylight saving entirely. The stated reason was earlier sunsets during the busy tourist season. The change moved the islands permanently to UTC-4, in line with several other Caribbean territories. [3]

Reversal in 2018 back to Eastern Time with DST

In 2018, following public consultation, the Turks and Caicos Islands reintroduced daylight saving time. From November 2018, the islands reverted to Eastern Standard Time (UTC-5) in winter and Eastern Daylight Time (UTC-4) in summer, matching the US East Coast year-round. [3] The islands now track the US East Coast through both seasons: EST (UTC-5) in winter, EDT (UTC-4) in summer. The IANA timezone America/Grand_Turk records this full back-and-forth in its transition history. The current alignment with the US East Coast suits the tourism economy, where most visitors arrive from American cities on Eastern Time.
