How does daylight saving affect NST to GMT?
The labels NST and GMT are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
Why can you trust this NST to GMT converter?
Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so NST to GMT stays accurate for today and for any past or future date you type in.

Frequently asked questions
How many hours ahead of NST is GMT?

Do NST or GMT use daylight saving time?
Newfoundland Standard Time (NST) observes daylight saving, alternating with NDT; Greenwich Mean Time (GMT) is a fixed offset with no daylight saving.
Why might the real-world NST–GMT difference change during the year?
The labels NST and GMT are fixed offsets, so this converter is always exact. But Newfoundland Standard Time's region switches between standard and summer time, so for part of the year you may actually want NDT to GMT. Always check which label a region is currently using before you schedule.
