NDT — Newfoundland Daylight Time
NDT is Newfoundland Daylight Time, 2 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 NDT 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
- Every zone listed here was on NDT.
NDT alternates with NST across the year.
Writing “NDT” for a date in the other half of the year is the most common time zone mistake in meeting invitations.
Convert NDT to other time zones
City clocks reflect whatever their zone is doing; where a city observes daylight saving time, its difference from NDT changes twice a year. Use the time zone converter for a specific date.

Why NDT is not an identifier
NDT 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; NDT and its 2 hours 30 minutes offset do not.
Frequently asked questions
What does NDT stand for?
NDT stands for Newfoundland Daylight Time. It is 2 hours 30 minutes behind UTC, written UTC-2:30.
What is NDT in UTC?
NDT is UTC-2:30. To convert an NDT time to UTC, add 2 hours 30 minutes.
What is the difference between NDT and NST?
NDT is the daylight saving form and NST the standard form of the same zones. The two are one hour apart and only one is ever in force at a time, so a recurring meeting written "NDT" shifts by an hour when the clocks change.
Which time zone should I use instead of NDT?
Use an IANA identifier — America/St_Johns for Newfoundland Daylight 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.
