Why people convert Seoul to NPT time
- Scheduling a call from Seoul to NPT: a 10:00 AM start in Seoul lands at 6:45 AM in NPT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Seoul and NPT are inside the 9-to-5 working day between 12:15 PM and 5:00 PM KST time (9:00 AM–1:45 PM NPT). That is roughly 4 hours 45 minutes of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Seoul is 4:45 PM in NPT makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM KST" is unambiguous; "3 PM" across a -3h 15m gap is not.
- Block 12:15 PM–5:00 PM KST as the recurring meeting window if you work primarily from Seoul and need NPT colleagues present.
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.
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).
