Why people convert COT to NPT time
- Scheduling a call from COT to NPT: a 10:00 AM start in COT lands at 8:45 PM in NPT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +10h 45m gap: COT and NPT 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 NPT is 7:45 PM in COT.
- Watching a live event or market open: COT viewers need 7:45 PM in NPT to catch a 9:00 AM start there, and 1:15 PM if the event is anchored to COT.
- Always state the zone abbreviation, not just the hour. "3:00 PM COT" 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 COT takes the early slot, the next week NPT does.
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.
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).
Best time to call between COT and NPT
