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 AEST
Australian Eastern Standard Time (AEST) is UTC+10. It is used in Sydney, Melbourne and Brisbane in the southern winter.
Australian Eastern Standard Time is UTC+10, covering Sydney, Melbourne, Brisbane and Canberra in winter. The complication is that Queensland does not observe daylight saving while New South Wales and Victoria do — so from October to April, Brisbane stays on AEST while Sydney moves to AEDT, and two cities on the same coast are an hour apart for half the year.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on AEST switches to AEDT (UTC+11) from October to April. So the 4.25-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.
