- •EDT is observed from the second Sunday of March to the first Sunday of November.
- •During EDT, the US East Coast is only 4 hours behind London (instead of 5).
- •Not all EST locations switch to EDT – Panama and Jamaica stay on EST year-round.
NST – Newfoundland Standard Time
UTC-03:30Newfoundland Standard Time (NST) is a unique half-hour offset time zone in Canada, 3.5 hours behind UTC.
- •NST is one of only a few half-hour offset time zones in the world.
- •Newfoundland joined Canada in 1949 and kept its unique time zone.
- •St. John's is the easternmost city in North America.
Time Conversion Guide: EDT to NST
EDT runs on Eastern Daylight Time (EDT) at UTC-04:00. NST runs on Newfoundland Standard Time (NST) at UTC-03:30. That puts EDT 30 minutes ahead of NST — a difference of +0h 30m at the current offsets.
In practice, when it is 9:00 AM in EDT it is 9:30 AM in NST. Midnight in EDT is 12:30 AM in NST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert EDT to NST time
- Scheduling a call from EDT to NST: a 10:00 AM start in EDT lands at 10:30 AM in NST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both EDT and NST are inside the 9-to-5 working day between 9:00 AM and 4:30 PM EDT time (9:30 AM–5:00 PM NST). That is roughly 7 hours 30 minutes of usable overlap.
- Watching a live event or market open: EDT viewers need 9:30 AM in NST to catch a 9:00 AM start there, and 11:30 PM if the event is anchored to EDT.
- Always state the zone abbreviation, not just the hour. "3:00 PM EDT" is unambiguous; "3 PM" across a +0h 30m gap is not.
- Block 9:00 AM–4:30 PM EDT as the recurring meeting window if you work primarily from EDT and need NST colleagues present.
About EDT (Eastern Daylight Time)
Eastern Daylight Time (EDT) is used during the summer months (second Sunday of March to the first Sunday of November) in the Eastern Time Zone. During EDT, clocks are advanced by one hour to take advantage of longer daylight hours. Not all locations in the Eastern Time Zone observe DST – Panama, Jamaica, and most of the Caribbean remain on EST year-round.
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 EDT and NST
Both EDT and NST sit inside the 9 AM – 5 PM working day between 9:00 AM–4:30 PM EDT, which is 9:30 AM–5:00 PM NST. That gives roughly 7 hours and 30 minutes of shared time — the safest window for a live call or meeting.
Business hours overlap
EDT and NST share 7 hours of working-hours overlap (9:00 AM–4:30 PM EDT), so scheduling a live meeting is straightforward.
EDT is 30 minutes ahead of NST (EDT UTC-04:00 → NST UTC-03:30). The shared working window is 9:00 AM–4:30 PM EDT. Remember to re-check around daylight-saving transitions.
