Why people convert Kathmandu to South Korea time
- Scheduling a call from Kathmandu to South Korea: a 10:00 AM start in Kathmandu lands at 1:15 PM in South Korea, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Kathmandu and South Korea are inside the 9-to-5 working day between 9:00 AM and 1:45 PM NPT time (12:15 PM–5:00 PM KST). That is roughly 4 hours 45 minutes of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Kathmandu is 11:15 PM in South Korea makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM NPT" is unambiguous; "3 PM" across a +3h 15m gap is not.
- Block 9:00 AM–1:45 PM NPT as the recurring meeting window if you work primarily from Kathmandu and need South Korea colleagues present.
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 KST (Korea Standard Time)
Korea Standard Time (KST) is the time zone used in South Korea. It shares the same UTC offset as Japan Standard Time but is a distinct time zone. South Korea does not observe daylight saving time. Seoul, the capital, is a major global tech and business hub.
