NPT and BST on the World Map
The map below highlights the NPT (Nepal Time) and BST (Greenwich Mean Time) timezone regions across the globe.
NPT – Nepal Time
UTC+05:45Nepal Time (NPT, UTC+05:45) is the time zone for Nepal — one of the few offsets in the world set on a 45-minute increment.
- •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.
GMT – Greenwich Mean Time
UTC+00:00Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London. It is the same as UTC+00:00.
- •GMT is based on the Prime Meridian (0° longitude) passing through Greenwich, London.
- •The Royal Observatory in Greenwich has been the reference point for GMT since 1884.
- •GMT and UTC are often used interchangeably, but UTC is based on atomic clocks.
- •Iceland uses GMT year-round and never observes daylight saving time.
- •The UK switches from GMT to BST (British Summer Time) in late March each year.

Understanding the -4h 45m Gap: Nepal vs London
Nepal runs on Nepal Time (NPT) at UTC+05:45. London runs on British Summer Time (BST) at UTC+01:00, also currently on daylight saving time. That puts Nepal 4 hours 45 minutes behind London — a difference of -4h 45m at the current offsets.
In practice, when it is 9:00 AM in Nepal it is 4:15 AM in London. Midnight in Nepal is 7:15 PM in London.London observes daylight saving time while Nepal does not, so the gap narrows or widens by an hour part of the year.

Why people convert Nepal to London time
- Scheduling a call from Nepal to London: a 10:00 AM start in Nepal lands at 5:15 AM in London, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Nepal and London are inside the 9-to-5 working day between 1:45 PM and 5:00 PM NPT time (9:00 AM–12:15 PM BST). That is roughly 3 hours 15 minutes of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Nepal is 3:15 PM in London 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 -4h 45m gap is not.
- Block 1:45 PM–5:00 PM NPT as the recurring meeting window if you work primarily from Nepal and need London colleagues present.
- London: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local 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).
About GMT (Greenwich Mean Time)
Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.
Best time to call between Nepal and London
Both Nepal and London sit inside the 9 AM – 5 PM working day between 1:45 PM–5:00 PM NPT, which is 9:00 AM–12:15 PM BST. That gives roughly 3 hours and 15 minutes of shared time — the safest window for a live call or meeting.
Business hours overlap
Nepal and London overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.
Nepal is 4 hours 45 minutes behind London (NPT UTC+05:45 → BST UTC+01:00). The shared working window is 1:45 PM–5:00 PM NPT. Remember to re-check around daylight-saving transitions.
