NCST
New Caledonia Standard Time
New Caledonia Standard Time (NCST) keeps the French territory of New Caledonia running on a rock‑steady UTC+11:00, with no daylight saving surprises. Whether you’re diving the lagoon of Nouméa or coordinating with partners across the Pacific, the time stays the same all year—making planning refreshingly straightforward.

About NCST
A fixed, year-round offset.
New Caledonia Standard Time (NCST) keeps the French territory of New Caledonia running on a rock‑steady UTC+11:00, with no daylight saving surprises. Whether you’re diving the lagoon of Nouméa or coordinating with partners across the Pacific, the time stays the same all year—making planning refreshingly straightforward.
IANA zones · the technical identifiers
The zone that resolve to NCST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about NCST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Why doesn’t New Caledonia observe daylight saving?
- New Caledonia lies in the tropics, about 20–22° south, where daylight hours change relatively little across the year. It tried daylight saving (UTC+12:00) in 1977–1979 and again in 1996–97, and has stayed on UTC+11:00 all year since March 1997.
- Is New Caledonia the only place that uses NCST?
- Yes. NCST refers only to New Caledonia's time. Other Pacific places on UTC+11:00, such as Vanuatu and the Solomon Islands, use their own time zone names.
- How does NCST line up with Australian time?
- During Australian winter, New Caledonia is one hour ahead of Sydney (UTC+10:00). When Australia moves into daylight saving (UTC+11:00), both are on the same UTC+11 offset. New Caledonia is one hour behind Auckland during New Zealand's winter and two hours behind while New Zealand is on daylight saving (UTC+13:00).
- Does New Caledonia ever change its clocks?
- No—there are no scheduled daylight saving transitions for New Caledonia Standard Time. Unless its legislation changes in the future, NCST will keep the same UTC+11 offset around the clock, year after year.
- Why might I see both “+11” and “NCST”?
- “+11” (or “UTC+11”) emphasizes the raw offset from Greenwich, while “NCST” is the region code that identifies New Caledonia as the representative zone. Both point to the same underlying time—Noumea—but NCST is more region‑specific.
