Why people convert Tokyo to Kathmandu time
- Scheduling a call from Tokyo to Kathmandu: a 10:00 AM start in Tokyo lands at 6:45 AM in Kathmandu, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Tokyo and Kathmandu are inside the 9-to-5 working day between 12:15 PM and 5:00 PM JST time (9:00 AM–1:45 PM NPT). That is roughly 4 hours 45 minutes of usable overlap.
- Coordinating a Tokyo-based team with Kathmandu contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM JST" is unambiguous; "3 PM" across a -3h 15m gap is not.
- Block 12:15 PM–5:00 PM JST as the recurring meeting window if you work primarily from Tokyo and need Kathmandu colleagues present.
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.
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).
