History
How Antigua and Barbuda keeps time.
Antigua and Barbuda adopted Atlantic Standard Time (UTC-4) as its standard time following colonial-era railway and telegraph practices that eventually became formal standard time in the region. The islands maintained this offset through independence in 1981, with no documented major time zone changes. Unlike much of North America and Europe, Antigua and Barbuda has never observed daylight saving time, consistent with the broader Caribbean practice of minimal seasonal clock adjustments.
