What This Means for Your Trip
Flight times: Flights from New York (JFK/EWR) to Aruba take approximately 4.5 hours. A noon departure from New York lands around 4–5 PM Aruba time (same time as Eastern during daylight saving, one hour ahead during standard time).
Calling home: If you’re on the US East Coast and want to call family during the day, the time difference is minimal — zero to one hour depending on the season. Calling from the US West Coast means Aruba is 3–4 hours ahead.
Sunrise and sunset: Because Aruba is close to the equator (12° north), day length doesn’t vary dramatically. Sunrise is approximately 6:30–7 AM year-round. Sunset is approximately 6:30–7 PM year-round. This consistency is one of the practical pleasures of being in the tropics.
