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).

Kathmandu vs EDT: Offsets, DST and Best Call Times

Kathmandu runs on Nepal Time (NPT) at UTC+05:45. EDT runs on Eastern Daylight Time (EDT) at UTC-04:00. That puts Kathmandu 9 hours 45 minutes behind EDT — a difference of -9h 45m at the current offsets.

In practice, when it is 9:00 AM in Kathmandu it is 11:15 PM in EDT on the previous day. Midnight in Kathmandu is 2:15 PM in EDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Kathmandu to EDT time

Scheduling a call from Kathmandu to EDT: a 10:00 AM start in Kathmandu lands at 12:15 AM in EDT, so you can confirm the slot without doing the arithmetic yourself.
Handling a -9h 45m gap: Kathmandu and EDT 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 EDT is 11:15 PM in Kathmandu.
Watching a live event or market open: Kathmandu viewers need 11:15 PM in EDT to catch a 9:00 AM start there, and 9:45 AM if the event is anchored to Kathmandu.

Always state the zone abbreviation, not just the hour. "3:00 PM NPT" is unambiguous; "3 PM" across a -9h 45m gap is not.
With a -9h 45m gap there is no shared 9-to-5 window, so alternate the early start: one week Kathmandu takes the early slot, the next week EDT 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 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.

Best time to call between Kathmandu and EDT

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

Business hours overlap

Kathmandu and EDT have no shared working hours because of the -9h 45m gap. Teams need to alternate early starts or rely on asynchronous handovers.

Kathmandu is 9 hours 45 minutes behind EDT (NPT UTC+05:45 → EDT UTC-04:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
