Why people convert Kathmandu to COT time

Scheduling a call from Kathmandu to COT: a 10:00 AM start in Kathmandu lands at 11:15 PM in COT the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -10h 45m gap: Kathmandu and COT 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 COT is 10:15 PM in Kathmandu.
Watching a live event or market open: Kathmandu viewers need 10:15 PM in COT to catch a 9:00 AM start there, and 10:45 AM if the event is anchored to Kathmandu.

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 COT 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 COT (Colombia Time)

Colombia Time (COT) is used throughout Colombia. Colombia does not observe daylight saving time. COT shares the same offset as EST (UTC-05:00). Bogotá, the capital, is one of the largest cities in South America.

Best time to call between Kathmandu and COT

With a -10h 45m offset there is no overlap inside a normal 9 AM – 5 PM day. COT opens at 9:00 AM COT, 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 COT 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 COT (NPT UTC+05:45 → COT 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.
