What NPT and GMT Actually Are
NPT — Nepal Time
Kathmandu, Pokhara. Standing at UTC+5:45 as written, and the region does not change its clocks, so that offset holds all year. Nepal sits at UTC+5:45 — one of only two zones in the world on a 45-minute offset.
Nepal is deliberately 15 minutes ahead of India, an offset chosen so the country keeps its own time rather than sharing its neighbor's.
GMT — Greenwich Mean Time
The UK and Ireland in winter, plus Iceland, Portugal and much of West Africa. Standing at UTC as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to GMT. Often used loosely as a synonym for UTC. They differ by less than a second, so for scheduling they are interchangeable.
Britain ran an experiment from 1968 to 1971 on permanent UTC+1, abandoning GMT entirely. It was scrapped after complaints about dark winter mornings in Scotland.
What This Means in Practice
Expect times on the half hour
NPT sits on a 45-minute offset rather than a whole hour, so a round number on one side is never a round number on the other. A 9:00 meeting becomes 45 minutes past the hour, which is exactly the detail calendar invitations get wrong when someone converts in their head.
This gap is not fixed
GMT changes its clocks and NPT does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, October 25, 2026 unless someone resets it.
