NPT and CDT on the World Map
The map below highlights the NPT (Nepal Time) and CDT (Central Daylight Time) timezone regions across the globe.
NPT – Nepal Time
UTC+05:45Nepal Time (NPT, UTC+05:45) is the time zone for Nepal — one of the few offsets in the world set on a 45-minute increment.
- •Nepal Time is UTC+05:45 — a 45-minute offset, not a whole or half hour.
- •The 45-minute offset was adopted in 1986 to match Kathmandu's solar time.
- •Nepal does not observe daylight saving time.
- •Nepal is 15 minutes ahead of India, despite sharing a long open border.
CDT – Central Daylight Time
UTC-05:00Central Daylight Time (CDT) is the daylight saving offset in the Central Time Zone, 5 hours behind UTC.
- •CDT is the same offset as EST (UTC-05:00), which can cause confusion.
- •CDT runs from the second Sunday in March to the first Sunday in November.
NPT to CDT Time Difference – Complete Guide
NPT runs on Nepal Time (NPT) at UTC+05:45. CDT runs on Central Daylight Time (CDT) at UTC-05:00. That puts NPT 10 hours 45 minutes behind CDT — a difference of -10h 45m at the current offsets.
In practice, when it is 9:00 AM in NPT it is 10:15 PM in CDT on the previous day. Midnight in NPT is 1:15 PM in CDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NPT to CDT time
- Scheduling a call from NPT to CDT: a 10:00 AM start in NPT lands at 11:15 PM in CDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -10h 45m gap: NPT and CDT 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 CDT is 10:15 PM in NPT.
- Watching a live event or market open: NPT viewers need 10:15 PM in CDT to catch a 9:00 AM start there, and 10:45 AM if the event is anchored to NPT.
- 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 NPT takes the early slot, the next week CDT 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 CDT (Central Daylight Time)
Central Daylight Time (CDT) is observed during summer months in the US and Canadian portions of the Central Time Zone. Clocks are moved forward by one hour, aligning with Eastern Standard Time (EST). Most of Mexico and Central America do not observe CDT, staying on CST year-round.
Best time to call between NPT and CDT
With a -10h 45m offset there is no overlap inside a normal 9 AM – 5 PM day. CDT opens at 9:00 AM CDT, which is 10:15 PM in NPT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
NPT and CDT have no shared working hours because of the -10h 45m gap. Teams need to alternate early starts or rely on asynchronous handovers.
NPT is 10 hours 45 minutes behind CDT (NPT UTC+05:45 → CDT UTC-05:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
