Why people convert Nepal to Chicago time
- Scheduling a call from Nepal to Chicago: a 10:00 AM start in Nepal lands at 11:15 PM in Chicago the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -10h 45m gap: Nepal and Chicago 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 Chicago is 10:15 PM in Nepal.
- Keeping family and friends in sync: knowing that 8:00 PM in Nepal is 9:15 AM in Chicago makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM NPT" 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 Nepal takes the early slot, the next week Chicago does.
- Chicago: Clocks fall back on Sun, Nov 1, 2026. Any meeting series spanning that date will shift by an hour in local time.
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 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.
