Hamilton, Bermuda · UTC-3 ☆

Hamilton is in the Atlantic Standard Time timezone (AST/UTC-4 in winter, ADT/UTC-3 in summer), observing daylight saving.

Hamilton is the capital of Bermuda, a British Overseas Territory in the North Atlantic, about 1,070 kilometers east of North Carolina. It runs on Atlantic Standard Time, UTC-4 in winter and Atlantic Daylight Time, UTC-3, in summer.

Bermuda’s position is peculiar. It is far north, at 32 degrees North, more northerly than most Caribbean islands. Yet it uses Atlantic Time rather than Eastern Time, keeping it an hour ahead of New York in winter and matching New York during summer daylight saving.

Finance and the Bermuda clock

Bermuda is a major insurance and reinsurance center. Bermuda’s insurance market, particularly for catastrophe risk, is one of the most significant globally. Insurance contracts, regulatory filings, and trading activity need to align with London markets and New York markets. The UTC-4/-3 offset puts Hamilton squarely between them, overlapping with both during normal business hours.

The pink sand and sailing calendar

Bermuda’s tourism economy runs on a seasonal calendar. The spring and summer bring sailing, particularly the Newport-Bermuda Race, held every two years. The island’s famous pink sand beaches peak in summer. These tourist rhythms structure the service economy’s schedule across the warmer months.
