NST

Newfoundland Standard Time

Newfoundland Standard Time (NST) puts you half an hour ahead of Atlantic Time and an hour and a half ahead of Eastern Time (Toronto and Montreal), giving the island its own quiet rhythm—especially when daylight saving nudges clocks forward to NDT and evenings stretch a little longer into the Atlantic dusk.

IANA zones · the technical identifiers

The zone that resolve to NST.

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 NST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].

Why is Newfoundland’s time zone offset by half an hour?
Newfoundland sits geographically between two standard meridians, so it adopted a 30‑minute offset to better match local solar time and daily life on the island.
Does Newfoundland observe daylight saving time?
Yes. The region switches from NST to NDT in spring and back again in autumn, shifting the clock by one hour to make better use of daylight.
How does NDT affect meetings with Toronto or New York?
During NDT, Newfoundland is 90 minutes ahead of both Toronto and New York, so a 10 a.m. meeting in St. John's lands at 8:30 a.m. in Toronto and New York.
Is Newfoundland the only place with a half‑hour offset in North America?
It’s the only Canadian province with a standard half‑hour offset; most other half‑hour zones are in Asia and Oceania.
When does NDT end each year?
Clocks fall back from NDT to NST on the first Sunday in November, giving everyone an extra hour of sleep as the days grow shorter.
Do other Canadian provinces use NST?
No. Only the island of Newfoundland and southeastern Labrador follow NST/NDT; the rest of Labrador and Atlantic Canada use Atlantic Time.
Why is St. John’s the representative zone?
St. John’s is the capital and largest city on the island, making it the natural reference point for Newfoundland’s unique timekeeping.
