ICT to NST Time Difference – Complete Guide

ICT runs on Indochina Time (ICT) at UTC+07:00. NST runs on Newfoundland Standard Time (NST) at UTC-03:30. That puts ICT 10 hours 30 minutes behind NST — a difference of -10h 30m at the current offsets.

In practice, when it is 9:00 AM in ICT it is 10:30 PM in NST on the previous day. Midnight in ICT is 1:30 PM in NST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert ICT to NST time

Scheduling a call from ICT to NST: a 10:00 AM start in ICT lands at 11:30 PM in NST the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -10h 30m gap: ICT and NST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in NST is 10:30 PM in ICT.
Coordinating a ICT-based team with NST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a -10h 30m gap is not.
With a -10h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week ICT takes the early slot, the next week NST does.

About ICT (Indochina Time)

Indochina Time (ICT) is used across Southeast Asia including Vietnam, Thailand, Laos, and Cambodia. Indonesia (Western time, WIB) also uses UTC+07:00. ICT does not observe daylight saving time.

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 ICT and NST

With a -10h 30m offset there is no overlap inside a normal 9 AM – 5 PM day. NST opens at 9:00 AM NST, which is 10:30 PM in ICT, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

ICT and NST have no shared working hours because of the -10h 30m gap. Teams need to alternate early starts or rely on asynchronous handovers.

ICT is 10 hours 30 minutes behind NST (ICT UTC+07:00 → NST UTC-03:30). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
