About NPT
Nepal Time (NPT) is UTC+5:45. It is used in Nepal, all year.
Nepal Time is UTC+5:45 — the only zone in the world offset by three quarters of an hour, set so that noon falls over Kathmandu rather than over the Indian meridian fifteen minutes away. It breaks almost every piece of software that stores offsets in whole or half hours, and it is fifteen minutes ahead of India rather than the round number people assume.
About EST
Eastern Standard Time (EST) is UTC−5. It is used in New York, Toronto, Miami and Atlanta in winter.
Eastern Standard Time is UTC−5 and applies in New York, Toronto, Miami and Atlanta only from November to March. For the other eight months those cities are on EDT, UTC−4. Americans routinely write "EST" year-round to mean "east coast time", so a date given as EST in July is usually meant as EDT and is an hour earlier than written — one of the most common scheduling errors there is. Note also that Panama and Jamaica are on UTC−5 all year and never switch.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on EST switches to EDT (UTC−4) from March to November. So the 10.75-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.
NPT does not shift, so the whole change comes from one side. A recurring meeting fixed in NPT will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
Frequently asked questions
What time is 9:00 AM NPT in EST?
9:00 AM NPT is 10:15 PM EST (previous day).
Is EST ahead of NPT?
EST is 10 hours 45 minutes behind NPT.
Which time zone does this use?
NPT is UTC+5:45 and EST is UTC−5. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
