Current time in St. John's

Antigua and Barbuda keeps Atlantic Standard Time, UTC-4, throughout the year, with no daylight saving. St. John's, the capital, shares this clock with Barbuda and the country's other islands.

Two islands, one offset

The country is made up of Antigua and Barbuda, together with the small island of Redonda. Antigua holds the capital and the bulk of the population; Barbuda lies to the north, flatter and far more sparsely settled. Despite the sea between them, they run on the same clock — the offset is national, not per-island.

Antigua and Barbuda is part of the Leeward Islands in the eastern Caribbean, and the UTC-4 offset it uses is shared with much of that chain. Travel between neighbouring islands therefore tends to leave your watch alone, which is more than can be said for the connecting flights.

Two islands, three names on the map, and exactly one hour between them — the sea does not run on a separate schedule.

No seasonal change, and what follows from it

The country does not observe daylight saving time. At this latitude the length of the day varies little across the year, so there is no seasonal daylight to chase, and the clock simply stays where it is.

The practical effect shows up in comparisons with North America and Europe: Against US Eastern Time: one hour ahead in the northern winter, level in the northern summer Against the United Kingdom: the gap narrows by an hour when British clocks go forward

Against most of the eastern Caribbean: no difference at all, in either season Against South American countries on UTC-3: one hour behind In every case, the movement comes from the other party. Antigua and Barbuda holds still.

Places on the islands

Administratively the country is divided into parishes on Antigua, plus Barbuda and Redonda as dependencies. Some named places: St. John's — the capital and main port, in the northwest of Antigua English Harbour — on Antigua's southern coast, a historic anchorage

Codrington — the main settlement on Barbuda All Saints — inland on Antigua Redonda — uninhabited, southwest of Antigua
