Why people convert Kathmandu to EST time

Scheduling a call from Kathmandu to EST: a 10:00 AM start in Kathmandu lands at 11:15 PM in EST the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -10h 45m gap: Kathmandu and EST 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 EST is 10:15 PM in Kathmandu.
Coordinating a Kathmandu-based team with EST 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 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 Kathmandu takes the early slot, the next week EST 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 EST (Eastern Standard Time)

Eastern Standard Time (EST) is observed during the winter months in the eastern part of North America. It covers 23 US states and parts of Canada including Ontario and Quebec. EST is the most populous time zone in the United States, home to major financial centers like New York City and global organizations headquartered in Washington D.C. During daylight saving time (March–November), clocks shift to Eastern Daylight Time (EDT, UTC-04:00). The time zone also covers parts of the Caribbean and Central America including Panama, Jamaica, and the Cayman Islands.

Best time to call between Kathmandu and EST

With a -10h 45m offset there is no overlap inside a normal 9 AM – 5 PM day. EST opens at 9:00 AM EST, which is 10:15 PM in Kathmandu, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

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

Kathmandu is 10 hours 45 minutes behind EST (NPT UTC+05:45 → EST 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.
