- •Nepal Time is UTC+05:45 — a 45-minute offset, not a whole or half hour.
- •The 45-minute offset was adopted in 1986 to match Kathmandu's solar time.
- •Nepal does not observe daylight saving time.
- •Nepal is 15 minutes ahead of India, despite sharing a long open border.
ICT – Indochina Time
UTC+07:00Indochina Time (ICT) is the time zone for Vietnam, Thailand, Laos, and Cambodia, 7 hours ahead of UTC.
- •Bangkok is one of the most visited cities in the world.
- •ICT is 12 hours ahead of EST.

Understanding the +1h 15m Gap: Nepal vs Vietnam
Nepal runs on Nepal Time (NPT) at UTC+05:45. Vietnam runs on Indochina Time (ICT) at UTC+07:00. That puts Nepal 1 hour 15 minutes ahead of Vietnam — a difference of +1h 15m at the current offsets.
In practice, when it is 9:00 AM in Nepal it is 10:15 AM in Vietnam. Midnight in Nepal is 1:15 AM in Vietnam. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Nepal to Vietnam time
- Scheduling a call from Nepal to Vietnam: a 10:00 AM start in Nepal lands at 11:15 AM in Vietnam, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Nepal and Vietnam are inside the 9-to-5 working day between 9:00 AM and 3:45 PM NPT time (10:15 AM–5:00 PM ICT). That is roughly 6 hours 45 minutes of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Nepal is 9:15 PM in Vietnam 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 +1h 15m gap is not.
- Block 9:00 AM–3:45 PM NPT as the recurring meeting window if you work primarily from Nepal and need Vietnam 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 ICT (Indochina Time)
Indochina Time (ICT) is used across Southeast Asia including Vietnam, Thailand, Laos, and Cambodia. Indonesia (Western time, WIB) also uses UTC+07:00. ICT does not observe daylight saving time.
Best time to call between Nepal and Vietnam

Business hours overlap
Nepal and Vietnam share 6 hours of working-hours overlap (9:00 AM–3:45 PM NPT), so scheduling a live meeting is straightforward.
Nepal is 1 hour 15 minutes ahead of Vietnam (NPT UTC+05:45 → ICT UTC+07:00). The shared working window is 9:00 AM–3:45 PM NPT. Remember to re-check around daylight-saving transitions.
