Why people convert Dublin to Nepal time
- Scheduling a call from Dublin to Nepal: a 10:00 AM start in Dublin lands at 2:45 PM in Nepal, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Dublin 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.
- Coordinating a Dublin-based team with Nepal contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- 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 Dublin and need Nepal colleagues present.
- Dublin: 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 Dublin and Nepal
Both Dublin 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
