NST — Newfoundland Standard Time
NST is Newfoundland Standard Time, 3 hours 30 minutes behind UTC. It is a fixed offset: unlike a time zone, it does not change with the season — the zones that use it switch to a different abbreviation instead.

Is NST in force right now?
A zone only carries this abbreviation for part of the year. This is which of them were on it at 2 Aug 2026 07:46 UTC; the list is re-derived against your own clock when scripts load.

Using a different abbreviation
- America/St_Johns — on NDT (UTC-2:30)
NST alternates with NDT across the year.
Writing “NST” for a date in the other half of the year is the most common time zone mistake in meeting invitations.
Convert NST to other time zones
City clocks reflect whatever their zone is doing; where a city observes daylight saving time, its difference from NST changes twice a year. Use the time zone converter for a specific date.

Why NST is not an identifier
NST is shorthand, not a standard. There is no registry of time zone abbreviations, no authority that assigns them, and nothing preventing two regions from adopting the same three letters — which is what makes codes like IST and CST unusable without context.
For anything a machine will read — a calendar invitation, a database column, an API response — use the IANA identifier of the zone (America/St_Johns, for example) or an explicit UTC offset alongside the date. The identifier survives a change in the law; NST and its 3 hours 30 minutes offset do not.
Frequently asked questions
What does NST stand for?
NST stands for Newfoundland Standard Time. It is 3 hours 30 minutes behind UTC, written UTC-3:30.
What is NST in UTC?
NST is UTC-3:30. To convert an NST time to UTC, add 3 hours 30 minutes.
What is the difference between NST and NDT?
NST is the standard-time form; NDT is what those same zones use during daylight saving time, one hour ahead. A summer date written "NST" is usually a mistake for NDT.
Which time zone should I use instead of NST?
Use an IANA identifier — America/St_Johns for Newfoundland Standard Time — or state the UTC offset with the date. Abbreviations are not identifiers: they are not unique, they are not registered anywhere, and half of them change with the season. Calendar software resolves this automatically when you pick a city rather than typing letters.
