What time zone does the Netherlands (Amsterdam) use?

The Netherlands uses Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) in summer. DST starts on the last Sunday of March and ends on the last Sunday of October, following the EU standard.

What time zones do the Caribbean territories of the Netherlands use?

Aruba, Curacao, and Sint Maarten all use Atlantic Standard Time (AST, UTC-4) year-round. None of them observe daylight saving time, so their UTC offset never changes.

What is the time difference between Amsterdam and Aruba?

During CET (winter), Amsterdam is 5 hours ahead of Aruba. During CEST (summer), Amsterdam is 6 hours ahead of Aruba, because the Caribbean territories do not change their clocks.

What is the IANA time zone identifier for Amsterdam?

The IANA identifier for Amsterdam (and all of the Netherlands in Europe) is Europe/Amsterdam. For the Caribbean territories: America/Aruba, America/Curacao, and America/Lower_Princes (Sint Maarten).

Does the Netherlands observe daylight saving time?

Yes, but only the European part. The Netherlands moves clocks forward 1 hour to CEST (UTC+2) on the last Sunday of March, and back to CET (UTC+1) on the last Sunday of October. The Caribbean territories — Aruba, Curacao, and Sint Maarten — do not observe DST.

What is the time difference between Amsterdam and New York?

During CET/EST (winter), Amsterdam (UTC+1) is 6 hours ahead of New York (UTC-5). During CEST/EDT (summer), Amsterdam (UTC+2) is 6 hours ahead of New York (UTC-4). The gap stays at 6 hours most of the year because both regions observe DST, though the transitions are not always simultaneous.

Are Bonaire, Sint Eustatius, and Saba included?

Those three islands are special municipalities of the Netherlands (not constituent countries), and they use AST (UTC-4) as well, the same as Aruba and Curacao. They do not observe DST.
