Why people convert Bangkok to NPT time
- Scheduling a call from Bangkok to NPT: a 10:00 AM start in Bangkok lands at 8:45 AM in NPT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Bangkok 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.
- Keeping family and friends in sync: knowing that 8:00 PM in Bangkok is 6:45 PM in NPT makes it easy to avoid calling at 3 AM.
- 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 Bangkok 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).
