History
How Cook Islands keeps time.
Under New Zealand administration, the Cook Islands kept local mean time until 1952, when they adopted UTC-10:30. In 1978 they moved to UTC-10:00 and began observing half-hour daylight saving time (UTC-09:30) each southern summer, which ended after March 1991; the islands have kept UTC-10:00 year-round since. This consistency has supported local activities and coordination with international partners, particularly New Zealand and other Pacific nations.
