NST time now (Newfoundland Standard Time)

What NST means

NST stands for Newfoundland Standard Time, UTC−3:30. It is used in Newfoundland and southeastern Labrador.

It is a standard (winter) time. Places on NST that observe daylight saving time switch to NDT (UTC−2:30) in summer, so NST is a fixed offset while the local clock is not.

Where and when NST is used

1 zone uses it for part of the year only, switching to daylight saving time in the other months. Computed from tzdata under the current rules.

How long NST has been used

In the tzdata record, St. John's has used NST since 1884.

NST in the past

Zones whose tzdata history shows NST before 2025 but that no longer use it:

• America/Adak (Adak): 1900–1967
• America/Nome (Nome): 1900–1967
• America/Goose_Bay (Goose Bay): 1884–1966

NST converted to other zones

Every column is a fixed offset, so this table is valid on any date. Remember that the regions behind some columns switch to summer time (EST to EDT, CET to CEST, GMT to BST); the clock in those cities is then an hour later than the column.
