Understanding the +3h 45m Gap: Oslo vs Kathmandu
Oslo runs on Central European Summer Time (CEST) at UTC+02:00, currently observing daylight saving time. Kathmandu runs on Nepal Time (NPT) at UTC+05:45. That puts Oslo 3 hours 45 minutes ahead of Kathmandu — a difference of +3h 45m at the current offsets.
In practice, when it is 9:00 AM in Oslo it is 12:45 PM in Kathmandu. Midnight in Oslo is 3:45 AM in Kathmandu.Oslo observes daylight saving time while Kathmandu does not, so the gap narrows or widens by an hour part of the year.

Why people convert Oslo to Kathmandu time
- Scheduling a call from Oslo to Kathmandu: a 10:00 AM start in Oslo lands at 1:45 PM in Kathmandu, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Oslo and Kathmandu are inside the 9-to-5 working day between 9:00 AM and 1:15 PM CEST time (12:45 PM–5:00 PM NPT). That is roughly 4 hours 15 minutes of usable overlap.
- Coordinating a Oslo-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 CEST" is unambiguous; "3 PM" across a +3h 45m gap is not.
- Block 9:00 AM–1:15 PM CEST as the recurring meeting window if you work primarily from Oslo and need Kathmandu colleagues present.
- Oslo: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +3h 45m gap.
About CET (Central European Time)
Central European Time (CET) is the standard time zone for most of Europe, covering over 30 countries from Spain to Poland, and from Norway to Italy. CET is 1 hour ahead of GMT and is used by the European Union's most populous nations. During summer, most CET countries switch to Central European Summer Time (CEST, UTC+02:00). Major European financial markets in Frankfurt, Paris, and Amsterdam operate on CET.
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 Oslo and Kathmandu
Both Oslo and Kathmandu sit inside the 9 AM – 5 PM working day between 9:00 AM–1:15 PM CEST, which is 12:45 PM–5:00 PM NPT. That gives roughly 4 hours and 15 minutes of shared time — the safest window for a live call or meeting.
Business hours overlap
Oslo and Kathmandu overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.
Oslo is 3 hours 45 minutes ahead of Kathmandu (CEST UTC+02:00 → NPT UTC+05:45). The shared working window is 9:00 AM–1:15 PM CEST. Remember to re-check around daylight-saving transitions.
