Everything You Need to Know About GST and NST Time

GST runs on Gulf Standard Time (GST) at UTC+04:00. NST runs on Newfoundland Standard Time (NST) at UTC-03:30. That puts GST 7 hours 30 minutes behind NST — a difference of -7h 30m at the current offsets.

In practice, when it is 9:00 AM in GST it is 1:30 AM in NST. Midnight in GST is 4:30 PM in NST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert GST to NST time

Scheduling a call from GST to NST: a 10:00 AM start in GST lands at 2:30 AM in NST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both GST and NST are inside the 9-to-5 working day between 4:30 PM and 5:00 PM GST time (9:00 AM–9:30 AM NST). That is roughly 0 hours 30 minutes of usable overlap.
Watching a live event or market open: GST viewers need 1:30 AM in NST to catch a 9:00 AM start there, and 7:30 AM if the event is anchored to GST.

Always state the zone abbreviation, not just the hour. "3:00 PM GST" is unambiguous; "3 PM" across a -7h 30m gap is not.
Block 4:30 PM–5:00 PM GST as the recurring meeting window if you work primarily from GST and need NST colleagues present.

About GST (Gulf Standard Time)

Gulf Standard Time (GST) is the time zone used in the United Arab Emirates, Oman, and other Gulf states. GST does not observe daylight saving time. Dubai and Abu Dhabi, major international business and tourism hubs, operate on GST.

About NST (Newfoundland Standard Time)

Newfoundland Standard Time (NST) is one of the few half-hour offset time zones in the world. It covers the island of Newfoundland in Canada and is 30 minutes ahead of Atlantic Standard Time. This unique offset exists because Newfoundland was an independent country until 1949.

Best time to call between GST and NST

Both GST and NST sit inside the 9 AM – 5 PM working day between 4:30 PM–5:00 PM GST, which is 9:00 AM–9:30 AM NST. That gives roughly 0 hours and 30 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

GST and NST overlap for only 30 minutes (4:30 PM–5:00 PM GST), so meetings have to be booked precisely.

GST is 7 hours 30 minutes behind NST (GST UTC+04:00 → NST UTC-03:30). The shared working window is 4:30 PM–5:00 PM GST. Remember to re-check around daylight-saving transitions.
