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 +10h 45m Gap: Chicago vs Nepal

Chicago runs on Central Daylight Time (CDT) at UTC-05:00, currently observing daylight saving time. Nepal runs on Nepal Time (NPT) at UTC+05:45. That puts Chicago 10 hours 45 minutes ahead of Nepal — a difference of +10h 45m at the current offsets.

In practice, when it is 9:00 AM in Chicago it is 7:45 PM in Nepal. Midnight in Chicago is 10:45 AM in Nepal.Chicago observes daylight saving time while Nepal does not, so the gap narrows or widens by an hour part of the year.

Why people convert Chicago to Nepal time

Scheduling a call from Chicago to Nepal: a 10:00 AM start in Chicago lands at 8:45 PM in Nepal, so you can confirm the slot without doing the arithmetic yourself.
Handling a +10h 45m gap: Chicago and Nepal 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 Nepal is 7:45 PM in Chicago.
Coordinating a Chicago-based team with Nepal contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM CDT" is unambiguous; "3 PM" across a +10h 45m gap is not.
With a +10h 45m gap there is no shared 9-to-5 window, so alternate the early start: one week Chicago takes the early slot, the next week Nepal does.
Chicago: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +10h 45m gap.

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 Chicago and Nepal

With a +10h 45m offset there is no overlap inside a normal 9 AM – 5 PM day. Nepal opens at 9:00 AM NPT, which is 7:45 PM in Chicago, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Chicago and Nepal have no shared working hours because of the +10h 45m gap. Teams need to alternate early starts or rely on asynchronous handovers.

Chicago is 10 hours 45 minutes ahead of Nepal (CDT UTC-05:00 → 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.
