History
How Curaçao keeps time.
Curaçao, as part of the Netherlands Antilles, has maintained Atlantic Standard Time (AST) as its sole official time standard for decades. Before that, from 1912 to 1965, the island kept UTC-04:30; it moved to UTC-04:00 on January 1, 1965.
When the Netherlands Antilles dissolved in 2010 and Curaçao became a separate constituent country within the Kingdom of the Netherlands, it retained AST without interruption. Unlike many Caribbean nations that experimented with daylight saving time, Curaçao's near-equatorial location—just 12° north of the equator—meant there's virtually no seasonal variation in daylight hours, eliminating any practical rationale for DST observance.
Did you know?
Things about Curaçao's time.
Being so close to the equator, Curaçao experiences remarkably consistent daylight year-round—sunrise and sunset times vary by less than an hour throughout the entire year. This means UTC−04:00 isn't just administratively convenient; it lines up fairly naturally with solar time, giving the island practical morning and evening light patterns every single day.
For visitors from the U.S. East Coast, AST (UTC−04:00) is the same as Eastern Daylight Time (EDT), so from March to early November their watches stay unchanged.
