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).

Understanding the -9h 15m Gap: Kathmandu vs NST

Kathmandu runs on Nepal Time (NPT) at UTC+05:45. NST runs on Newfoundland Standard Time (NST) at UTC-03:30. That puts Kathmandu 9 hours 15 minutes behind NST — a difference of -9h 15m at the current offsets.

In practice, when it is 9:00 AM in Kathmandu it is 11:45 PM in NST on the previous day. Midnight in Kathmandu is 2:45 PM in NST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Kathmandu to NST time

Scheduling a call from Kathmandu to NST: a 10:00 AM start in Kathmandu lands at 12:45 AM in NST, so you can confirm the slot without doing the arithmetic yourself.
Handling a -9h 15m gap: Kathmandu 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 11:45 PM in Kathmandu.
Booking travel or deliveries: tracking NST local time against Kathmandu keeps pickup windows and arrival estimates honest across the -9h 15m offset.

Always state the zone abbreviation, not just the hour. "3:00 PM NPT" is unambiguous; "3 PM" across a -9h 15m gap is not.
With a -9h 15m gap there is no shared 9-to-5 window, so alternate the early start: one week Kathmandu takes the early slot, the next week NST does.

About NPT (Nepal Time)

Nepal Time (NPT) runs at UTC+05:45, one of only a handful of time zones worldwide that are not a whole or half hour from UTC. Nepal set its offset to 5 hours 45 minutes ahead of UTC in 1986 to mark the country's position between the 75°E and 90°E meridians; Kathmandu's solar time sits just over 5 hours 41 minutes ahead of Greenwich, so the 45-minute offset tracks the sun more closely than either 5:30 or 6:00 would. Nepal does not observe daylight saving time, so NPT is fixed all year. The offset makes Nepal 15 minutes ahead of India Standard Time (UTC+05:30) and 2 hours 15 minutes ahead of Dubai (UTC+04:00).

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 Kathmandu and NST

With a -9h 15m offset there is no overlap inside a normal 9 AM – 5 PM day. NST opens at 9:00 AM NST, which is 11:45 PM in Kathmandu, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Kathmandu and NST have no shared working hours because of the -9h 15m gap. Teams need to alternate early starts or rely on asynchronous handovers.

Kathmandu is 9 hours 15 minutes behind NST (NPT UTC+05:45 → 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.
