About New Zealand Standard Time (NZST)
New Zealand Standard Time (NZST, IANA: Pacific/Auckland) is the civil time of New Zealand mainland (North Island + South Island), set at UTC+12:00. NZST is observed in winter; New Zealand switches to New Zealand Daylight Time (NZDT = UTC+13) from the last Sunday of September to the first Sunday of April per the Time Act of 1974 + Standard Time Act of 2007 (a slightly different DST schedule than Australia + most of the Northern Hemisphere). The Chatham Islands archipelago (Chatham, Pitt Islands — 800 km east of NZ mainland) uses Chatham Standard Time (CHAST = UTC+12:45) and Chatham Daylight Time (CHADT = UTC+13:45) — one of the world's only 45-minute-offset zones along with Nepal UTC+5:45 and Eucla WA UTC+8:45. NZST serves approximately 5.2 million New Zealanders. NZST is identical in offset to Fiji Time (FJT), Marshall Islands Time, Tuvalu Time, Wallis and Futuna Time. Major NZST cities: Auckland (1.7M metro — North Island), Wellington (210K city, 425K metro — capital), Christchurch (380K — South Island), Hamilton (180K), Tauranga (155K), Dunedin (135K), Queenstown (25K — tourist hub + Lord of the Rings filming locations). Affects: NZX (New Zealand Stock Exchange) trading hours, All Blacks rugby match scheduling, Hobbiton + Milford Sound tourism operating hours.
About Atlantic Standard Time (AST)
Atlantic Standard Time (AST, IANA: America/Halifax, America/Puerto_Rico) is the time zone for the Canadian Maritime provinces and most of the Caribbean, set at UTC-4:00. AST is observed in: Nova Scotia, New Brunswick, Prince Edward Island, Labrador (partially), Newfoundland's Labrador portion, eastern Quebec, Puerto Rico, US Virgin Islands, Bermuda, Anguilla, Antigua, Aruba, Barbados, British Virgin Islands, Curaçao, Dominica, Grenada, Guadeloupe, Martinique, Saint Lucia, Saint Vincent, Trinidad and Tobago, and Venezuela (since 2007). Canadian Maritime provinces observe AST in winter and switch to ADT = UTC-3:00 in summer per the Energy Policy Act-aligned Canadian schedule. The Caribbean territories (Puerto Rico, USVI, Bermuda) and US territories observe AST year-round without DST per their territorial governments. AST is the same offset as EDT (Eastern Daylight Time) during US summer months, so Halifax and New York are on the same clock in summer but Halifax is one hour ahead in winter.
