Aruba stays on AST (UTC-4) year-round — no Daylight Saving Time. Compare Aruba time with the US East Coast and Europe.
Aruba: crystal clear water, 365 days of sunshine, and a timezone that never changes. The island paradise uses Atlantic Standard Time (AST, UTC−4) year-round, making it one of the easiest Caribbean destinations to schedule with from the US East Coast. This guide covers everything you need to know about Aruba time — whether you're planning a vacation, scheduling a business call, or watching a live event from the island.
Aruba Time Zone: AST (UTC−4), No DST
Aruba permanently observes Atlantic Standard Time (AST), which is UTC−4 year-round. The IANA identifier is America/Aruba. Like its sister islands Curaçao and Bonaire (the ABC islands), Aruba has never observed Daylight Saving Time — the proximity to the equator makes seasonal time changes unnecessary and impractical.

ℹ️ Aruba & US Eastern Time
In winter (November–March), Aruba is exactly 1 hour ahead of New York/Miami. In summer (March–November), when the US switches to EDT (UTC−4), Aruba and the US East Coast are in the SAME timezone. This makes Aruba uniquely easy to stay connected with business contacts back home during a vacation — no confusing time math required in summer.
Expert Tip — Live Events from Aruba
Aruba's UTC−4 means US prime-time events land at reasonable hours. NFL Sunday Night Football (8:20 PM ET) broadcasts at 9:20 PM Aruba time in winter — a perfect evening event. NBA games (7:00 PM ET) start at 8:00 PM in Aruba. This is significantly better than watching from Europe or Asia, where these events air in the middle of the night.
