Does it account for Daylight Saving Time?

Yes, our converter uses the IANA timezone database, which includes all current DST rules for every timezone in the world.

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All timezones are defined as offsets from UTC.

Can I compare multiple timezones at once?

Yes, you can add multiple cities or timezones and see the equivalent times side by side.

How many timezones are there in the world?

There are 38 distinct UTC offsets in use, ranging from UTC-12 to UTC+14. This includes half-hour (UTC+5:30 India, UTC+9:30 Australia) and 45-minute offsets (UTC+5:45 Nepal, UTC+8:45 Australia).

What is the International Date Line?

The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. When you cross it westward, you gain a day; crossing eastward, you lose a day.

Why do some timezones have 30 or 45 minute offsets?

Countries chose offsets that best matched their solar noon. India uses UTC+5:30 and Nepal uses UTC+5:45 because standard hourly offsets didn't align well with their geography.

Which country has the most timezones?

France has the most (12 timezones) due to overseas territories. Russia spans 11 timezones. The US has 6 (including Hawaii and Alaska).

Comparing Time Zones: NST and ICT

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

In practice, when it is 9:00 AM in NST it is 7:30 PM in ICT. Midnight in NST is 10:30 AM in ICT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NST to ICT time

Scheduling a call from NST to ICT: a 10:00 AM start in NST lands at 8:30 PM in ICT, so you can confirm the slot without doing the arithmetic yourself.
Handling a +10h 30m gap: NST and ICT 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 ICT is 7:30 PM in NST.
Keeping family and friends in sync: knowing that 8:00 PM in NST is 6:30 AM in ICT makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM NST" 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 NST takes the early slot, the next week ICT does.

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.

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.

Best time to call between NST and ICT

With a +10h 30m offset there is no overlap inside a normal 9 AM – 5 PM day. ICT opens at 9:00 AM ICT, which is 7:30 PM in NST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

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

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