IST and NPT on the World Map
The map below highlights the IST (Greenwich Mean Time) and NPT (Nepal Time) timezone regions across the globe.
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.
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.
Comparing Time Zones: Ireland and Nepal
Ireland runs on Irish Standard Time (IST) at UTC+01:00, currently observing daylight saving time. Nepal runs on Nepal Time (NPT) at UTC+05:45. That puts Ireland 4 hours 45 minutes ahead of Nepal — a difference of +4h 45m at the current offsets.
In practice, when it is 9:00 AM in Ireland it is 1:45 PM in Nepal. Midnight in Ireland is 4:45 AM in Nepal.Ireland observes daylight saving time while Nepal does not, so the gap narrows or widens by an hour part of the year.

Why people convert Ireland to Nepal time
- Scheduling a call from Ireland to Nepal: a 10:00 AM start in Ireland lands at 2:45 PM in Nepal, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Ireland and Nepal are inside the 9-to-5 working day between 9:00 AM and 12:15 PM IST time (1:45 PM–5:00 PM NPT). That is roughly 3 hours 15 minutes of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Ireland is 12:45 AM in Nepal makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +4h 45m gap is not.
- Block 9:00 AM–12:15 PM IST as the recurring meeting window if you work primarily from Ireland and need Nepal colleagues present.
- Ireland: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +4h 45m gap.
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.
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 Ireland and Nepal
Both Ireland and Nepal sit inside the 9 AM – 5 PM working day between 9:00 AM–12:15 PM IST, which is 1:45 PM–5:00 PM NPT. That gives roughly 3 hours and 15 minutes of shared time — the safest window for a live call or meeting.
Business hours overlap
Ireland and Nepal overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.
Ireland is 4 hours 45 minutes ahead of Nepal (IST UTC+01:00 → NPT UTC+05:45). The shared working window is 9:00 AM–12:15 PM IST. Remember to re-check around daylight-saving transitions.
