Timezone abbreviation
CHADT currently resolves here through Pacific/Chatham, where the live offset is +12:45 (GMT+12:45). This page expands that into the broader meaning set, top cities, countries, similar labels, and safer exact-zone equivalents.
Last updated Apr 26, 2026. Representative zones, offset ranges, and city usage are refreshed from the current timezone dataset so abbreviation pages stay tied to real zones instead of static boilerplate.
CHADT is used in this dataset for Chatham Time. Right now it maps to 1 meaning, 1 IANA zone, and 1 country.
This page uses Pacific/Chatham as the live reference at +12:45 (GMT+12:45). CHADT works more as a reference label here than as a city-anchored civil-time label, so the IANA zone is what carries the practical weight.
CHADT currently shows +12:45, but Pacific/Chatham observes seasonal clock changes — the next transition is around September 27, 2026. That means the offset on this page is a snapshot, not a permanent fact, so long-range scheduling should pin the underlying IANA zone instead of the abbreviation.

CHADT is far ahead of UTC, into the Pacific island band, so the same calendar day finishes here before North America wakes up. In practice it is read inside Atlantic, Pacific, or Indian Ocean island cluster, where the leading city anchors are reference-only timezone clusters.
CHADT is unusually unambiguous: it ties to a single country and a single IANA zone, which is closer to a national clock label than a multi-region abbreviation.
CHADT shows up on airline schedules, weather bulletins, and Pacific shipping notices more than on office calendars. CHADT can also flip to a sibling daylight-saving abbreviation later in the year, so timestamps before and after the change need to be read carefully.
New Zealand sits in Oceania, specifically Australia and New Zealand. Population 5,324,700, area 268,838 km², capital Wellington. Civic markers behind CHADT include English, Māori, and New Zealand Sign Language and NZD (New Zealand dollar, $).
New Zealand backdrop: New Zealand is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island and the South Island —and over 600 smaller islands. It is the sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland.
CHADT in the Chatham Time meaning runs 12h45m ahead of UTC through Atlantic, Pacific, or Indian Ocean island cluster, threading zones such as Pacific/Chatham (cities: reference cities). Country anchors: New Zealand.

CHADT is not heavily split in the current catalog, but the short label still hides the underlying IANA zone and any future policy change. The safe pattern is to write the abbreviation for humans and the zone for machines.
Pacific/Chatham has an upcoming offset change on September 27, 2026. After that point, CHADT on this page will read a different UTC offset until the next transition, so any saved timestamp should anchor to the IANA zone rather than the abbreviation.
For precise work, the safest equivalent of CHADT is the exact IANA zone used by your city or system. Pacific/Chatham sits at +12:45, ahead of UTC, which means daily logs in this zone reach a new calendar date before UTC does — a small detail that breaks date-based reporting if missed.
Within this single zone (Pacific/Chatham, +12:45), CHADT is unambiguous, so the abbreviation and the IANA zone effectively interchange.
