Languages & native names

Languages listed for Cook Islands in the reference source, with native language names where available. This is not an exhaustive list of the languages spoken or a statement of their legal status.

The small codes are source language tags. A tag such as en-US includes a language and a regional variant; it is different from an ISO country code on its own.

Cook Islands time zones

1 identifier is listed for CK in IANA zone.tab, release 2026d. Time-zone identifiers describe clock-rule locations, not fixed UTC offsets.

• Pacific/Rarotonga

UTC offsets and daylight-saving rules depend on the date and location. Use the time-zone converter to compare local times for a chosen date.

FIFA and IOC values are source references, not confirmation of current membership or event participation. FIPS 10-4 was withdrawn in 2008; legacy FIPS-style values are for interpreting older datasets and must not replace current ISO codes.
