Why people convert Kathmandu to Tokyo time
- Scheduling a call from Kathmandu to Tokyo: a 10:00 AM start in Kathmandu lands at 1:15 PM in Tokyo, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Kathmandu and Tokyo are inside the 9-to-5 working day between 9:00 AM and 1:45 PM NPT time (12:15 PM–5:00 PM JST). 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 Tokyo 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 Tokyo 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 JST (Japan Standard Time)
Japan Standard Time (JST) is the standard time zone for all of Japan. Japan does not observe daylight saving time. JST is 9 hours ahead of UTC and 14 hours ahead of EST. The Tokyo Stock Exchange, the world's third largest by market capitalization, operates on JST. South Korea uses the same offset (KST) but it is a distinct time zone.
