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).

CST to Kathmandu Time Difference – Complete Guide

CST runs on Central Standard Time (CST) at UTC-06:00. Kathmandu runs on Nepal Time (NPT) at UTC+05:45. That puts CST 11 hours 45 minutes ahead of Kathmandu — a difference of +11h 45m at the current offsets.

In practice, when it is 9:00 AM in CST it is 8:45 PM in Kathmandu. Midnight in CST is 11:45 AM in Kathmandu. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert CST to Kathmandu time

Scheduling a call from CST to Kathmandu: a 10:00 AM start in CST lands at 9:45 PM in Kathmandu, so you can confirm the slot without doing the arithmetic yourself.
Handling a +11h 45m gap: CST and Kathmandu 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 Kathmandu is 8:45 PM in CST.
Watching a live event or market open: CST viewers need 8:45 PM in Kathmandu to catch a 9:00 AM start there, and 12:15 PM if the event is anchored to CST.

Always state the zone abbreviation, not just the hour. "3:00 PM CST" is unambiguous; "3 PM" across a +11h 45m gap is not.
With a +11h 45m gap there is no shared 9-to-5 window, so alternate the early start: one week CST takes the early slot, the next week Kathmandu does.

About CST (Central Standard Time)

Central Standard Time (CST) covers the central region of North America. It is the second most populous time zone in the US, including major cities like Chicago, Houston, and Dallas. CST is also used in Mexico City and much of Central America including Guatemala, Honduras, El Salvador, and Costa Rica. During summer, most of the US and Canada switch to Central Daylight Time (CDT, UTC-05:00), while Mexico and Central American countries generally remain on CST.

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).

Best time to call between CST and Kathmandu

With a +11h 45m offset there is no overlap inside a normal 9 AM – 5 PM day. Kathmandu opens at 9:00 AM NPT, which is 8:45 PM in CST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

CST and Kathmandu have no shared working hours because of the +11h 45m gap. Teams need to alternate early starts or rely on asynchronous handovers.

CST is 11 hours 45 minutes ahead of Kathmandu (CST UTC-06:00 → NPT UTC+05:45). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
