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).

Everything You Need to Know About Kathmandu and MST Time

Kathmandu runs on Nepal Time (NPT) at UTC+05:45. MST runs on Mountain Standard Time (MST) at UTC-07:00. That puts Kathmandu 12 hours 45 minutes behind MST — a difference of -12h 45m at the current offsets.

In practice, when it is 9:00 AM in Kathmandu it is 8:15 PM in MST on the previous day. Midnight in Kathmandu is 11:15 AM in MST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Kathmandu to MST time

Scheduling a call from Kathmandu to MST: a 10:00 AM start in Kathmandu lands at 9:15 PM in MST the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -12h 45m gap: Kathmandu and MST 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 MST is 8:15 PM in Kathmandu.
Booking travel or deliveries: tracking MST local time against Kathmandu keeps pickup windows and arrival estimates honest across the -12h 45m offset.

Always state the zone abbreviation, not just the hour. "3:00 PM NPT" is unambiguous; "3 PM" across a -12h 45m gap is not.
With a -12h 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 MST 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 MST (Mountain Standard Time)

Mountain Standard Time (MST) covers the Rocky Mountain region of the United States and Canada. Arizona is notable for not observing daylight saving time, staying on MST year-round (except the Navajo Nation). The time zone includes major cities like Denver, Phoenix, Calgary, and Salt Lake City. During summer, most areas switch to Mountain Daylight Time (MDT, UTC-06:00).

Best time to call between Kathmandu and MST

With a -12h 45m offset there is no overlap inside a normal 9 AM – 5 PM day. MST opens at 9:00 AM MST, which is 8:15 PM in Kathmandu, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Kathmandu and MST have no shared working hours because of the -12h 45m gap. Teams need to alternate early starts or rely on asynchronous handovers.

Kathmandu is 12 hours 45 minutes behind MST (NPT UTC+05:45 → MST 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.
