Understanding the -11h 45m Gap: Nepal vs CST
Nepal runs on Nepal Time (NPT) at UTC+05:45. CST runs on Central Standard Time (CST) at UTC-06:00. That puts Nepal 11 hours 45 minutes behind CST — a difference of -11h 45m at the current offsets.
In practice, when it is 9:00 AM in Nepal it is 9:15 PM in CST on the previous day. Midnight in Nepal is 12:15 PM in CST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Nepal to CST time
- Scheduling a call from Nepal to CST: a 10:00 AM start in Nepal lands at 10:15 PM in CST the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -11h 45m gap: Nepal and CST 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 CST is 9:15 PM in Nepal.
- Watching a live event or market open: Nepal viewers need 9:15 PM in CST to catch a 9:00 AM start there, and 11:45 AM if the event is anchored to Nepal.
- Always state the zone abbreviation, not just the hour. "3:00 PM NPT" 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 Nepal takes the early slot, the next week CST 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 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.
Best time to call between Nepal and CST
With a -11h 45m offset there is no overlap inside a normal 9 AM – 5 PM day. CST opens at 9:00 AM CST, which is 9:15 PM in Nepal, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
Nepal and CST have no shared working hours because of the -11h 45m gap. Teams need to alternate early starts or rely on asynchronous handovers.
Nepal is 11 hours 45 minutes behind CST (NPT UTC+05:45 → CST UTC-06:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
