Current Time in NST (Newfoundland Standard Time)
About NST
The standard time for the island of Newfoundland, Canada. It has a unique half-hour offset. During summer, Newfoundland switches to Newfoundland Daylight Time (NDT).

Newfoundland Standard Time (NST)
Newfoundland Standard Time (NST) is a unique time zone observed only in the Canadian province of Newfoundland and Labrador, primarily on the island of Newfoundland and parts of southeastern Labrador. Its abbreviation, NST, stands for Newfoundland Standard Time, while its daylight saving variant is Newfoundland Daylight Time (NDT). The zone is distinguished by its unusual 30-minute offset from Coordinated Universal Time (UTC-3:30), making it a half-hour offset zone rather than the more common full-hour offsets.
Standard Offset and Daylight Saving
During standard time (fall and winter), Newfoundland Standard Time operates at UTC-3:30. From the second Sunday in March to the first Sunday in November, clocks advance by one hour to Newfoundland Daylight Time (NDT), which is UTC-2:30. This 30-minute shift is consistent with the province's historical choice to align with a half-hour offset, a practice shared by only a few regions worldwide, such as Iran and parts of Australia.
Geographic Coverage
NST/NDT is used exclusively in Canada, specifically in the province of Newfoundland and Labrador. The IANA time zone database includes America/St_Johns and Canada/Newfoundland for this zone. Major cities observing NST include St. John's (the provincial capital), Corner Brook, Gander, and Labrador City (though Labrador City follows Atlantic Time in practice due to its location). The zone covers the entire island of Newfoundland and the southeastern portion of Labrador, roughly east of the Strait of Belle Isle and south of the 52nd parallel.
Difference from Neighbouring Zones
Newfoundland Standard Time is notably 30 minutes ahead of Atlantic Standard Time (AST, UTC-4:00) and 30 minutes behind Greenland's West Greenland Time (UTC-3:00) during standard time. During daylight saving, NDT (UTC-2:30) is 30 minutes ahead of Atlantic Daylight Time (ADT, UTC-3:00) and 30 minutes behind Greenland's daylight time (UTC-2:00). This half-hour difference can cause confusion for scheduling across the border with the rest of Canada and the United States. For example, when it is 12:00 noon in St. John's (NST), it is 11:30 AM in Halifax (AST) and 10:30 AM in New York (EST).
Practical Business Hours Guidance
When conducting business across time zones, note that Newfoundland's 30-minute offset means standard coordination windows may shift. For instance, if you are in New York (EST) and want to call St. John's during business hours (9:00 AM to 5:00 PM NST), the corresponding time in New York is 7:30 AM to 3:30 PM EST. During daylight saving, the overlap is 8:30 AM to 4:30 PM EDT. For conference calls involving multiple North American zones, a good common window is 10:00 AM to 3:00 PM NST, which translates to 9:30 AM to 2:30 PM AST and 8:30 AM to 1:30 PM EST. Always double-check the current offset, as Newfoundland observes daylight saving on the same schedule as the United States and Canada, but the half-hour offset persists year-round.
Frequently Asked Questions
Why does Newfoundland have a 30-minute time zone?
Newfoundland's half-hour offset dates back to the 19th century when the region adopted a local mean time based on the meridian of St. John's (52°30' west). When standard time zones were established, the province chose to keep its unique offset to align with solar time and maintain a distinct identity. The offset is also practical: the island's eastern location means a full-hour offset would either push sunrise too early or sunset too late relative to civil time.
Does all of Labrador use Newfoundland Time?
No. Only the southeastern part of Labrador, roughly east of the Strait of Belle Isle and south of the 52nd parallel, observes Newfoundland Time. The western and northern parts of Labrador follow Atlantic Time (UTC-4:00 standard, UTC-3:00 daylight) to align with the rest of Atlantic Canada. For example, the town of Happy Valley-Goose Bay uses Atlantic Time.
What is the time difference between Newfoundland and New York?
During standard time, Newfoundland (NST, UTC-3:30) is 1 hour and 30 minutes ahead of New York (EST, UTC-5:00). During daylight saving, Newfoundland (NDT, UTC-2:30) is 1 hour and 30 minutes ahead of New York (EDT, UTC-4:00). So when it's noon in St. John's, it's 10:30 AM in New York.
Does Newfoundland observe Daylight Saving Time?
Yes, Newfoundland observes daylight saving time from the second Sunday in March to the first Sunday in November, the same schedule as most of Canada and the United States. Clocks spring forward one hour to Newfoundland Daylight Time (NDT, UTC-2:30) and fall back to Newfoundland Standard Time (NST, UTC-3:30).
What is the IANA time zone ID for Newfoundland?
The primary IANA time zone ID is America/St_Johns. An alias Canada/Newfoundland also exists for backward compatibility. These IDs cover the entire area that observes Newfoundland Standard Time.
Are there any other places that use UTC-3:30?
No, Newfoundland is the only region in the world that uses UTC-3:30 as its standard time offset. However, during daylight saving, some regions like Iran use UTC+3:30, but that is a different offset. The half-hour offset for NST/NDT is unique to Newfoundland and Labrador.
