Understanding the -1h 15m Gap: Vietnam vs NPT

Vietnam runs on Indochina Time (ICT) at UTC+07:00. NPT runs on Nepal Time (NPT) at UTC+05:45. That puts Vietnam 1 hour 15 minutes behind NPT — a difference of -1h 15m at the current offsets.

In practice, when it is 9:00 AM in Vietnam it is 7:45 AM in NPT. Midnight in Vietnam is 10:45 PM in NPT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Vietnam to NPT time

Scheduling a call from Vietnam to NPT: a 10:00 AM start in Vietnam lands at 8:45 AM in NPT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Vietnam and NPT are inside the 9-to-5 working day between 10:15 AM and 5:00 PM ICT time (9:00 AM–3:45 PM NPT). That is roughly 6 hours 45 minutes of usable overlap.
Watching a live event or market open: Vietnam viewers need 7:45 AM in NPT to catch a 9:00 AM start there, and 1:15 AM if the event is anchored to Vietnam.

Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a -1h 15m gap is not.
Block 10:15 AM–5:00 PM ICT as the recurring meeting window if you work primarily from Vietnam and need NPT colleagues present.

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.

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 Vietnam and NPT

Both Vietnam and NPT sit inside the 9 AM – 5 PM working day between 10:15 AM–5:00 PM ICT, which is 9:00 AM–3:45 PM NPT. That gives roughly 6 hours and 45 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

Vietnam and NPT share 6 hours of working-hours overlap (10:15 AM–5:00 PM ICT), so scheduling a live meeting is straightforward.

Vietnam is 1 hour 15 minutes behind NPT (ICT UTC+07:00 → NPT UTC+05:45). The shared working window is 10:15 AM–5:00 PM ICT. Remember to re-check around daylight-saving transitions.
