Which countries are 45 minutes off UTC?

Nepal at UTC+5:45, the Eucla region of Australia at UTC+8:45, and New Zealand's Chatham Islands at UTC+12:45. That is the complete list among the 419 zones we publish.

Why would a country choose a 45 minute offset?

Because the alternative rounds the Sun further out of position. Each of these three sits near a meridian that a whole or half hour offset would misrepresent by more than the fifteen minutes the odd offset costs in convenience.

Do the 45 minute zones observe daylight saving?

Only the Chatham Islands, which follow New Zealand's summer time and move to UTC+13:45. The quarter hour is preserved through the change rather than rounded away.

Why does this break software?

Because a great deal of code stores offsets as whole or half hours. Nepal and Eucla cannot be represented that way at all, and any conversion into or out of them changes the minutes as well as the hour.

Zones 45 minutes off the hour

3 of 419

UTC+5:45 (Asia/Kathmandu), UTC+8:45 (Australia/Eucla), UTC+13:45 (Pacific/Chatham). Everything else on Earth is a whole or half hour from UTC, and these 3 are the only offsets that force a clock conversion to carry a quarter-hour remainder.

Computed at 27 September 2026 at 02:19 UTC. Offsets are read live, so a zone that is mid-transition would move. None of the three has ever observed daylight saving, so in practice this list is as stable as anything on the site.

How this list was built

A remainder test across the whole database

Every one of the 419 zone identifiers we publish was asked for its current offset from UTC in minutes, and any whose offset leaves a remainder of 45 when divided by 60 is on this list. That is the entire test. It catches negative offsets correctly because the remainder is taken on the absolute value, which matters for the western hemisphere even though none of the current quarter-hour zones happen to be there.

The offsets are read at the instant of the request rather than stored, which is the same discipline the rest of the site uses. It makes no difference for these three, because none of them has ever moved its clocks for daylight saving, but the test would follow them if they did: a zone at UTC+8:45 that adopted summer time would become UTC+9:45 and would stay on this page.

The count of cities beside each zone is drawn from our 6,338 city catalogue, which covers settlements above 100,000 people plus 448 smaller originals. Two of the three zones here show zero cities, and that is real information rather than a gap: they are genuinely that thinly populated. Eucla's settlement is a roadhouse community of a few dozen, and the Chatham Islands hold a few hundred people.

Nepal: fifteen minutes ahead of India, on purpose

Asia/Kathmandu at UTC+5:45 is the only quarter-hour zone with a serious population behind it, and its existence is a rounding argument with a neighbour. India keeps UTC+5:30, a half-hour offset chosen to split the difference across a very wide country. Nepal's meridian, taken at Gaurishankar near the Tibetan border, sits far enough east to justify another fifteen minutes, and Nepal took them. The result is a border you can walk across that puts your watch fifteen minutes out.

That is the single most common failure in date-handling software. A system that stores a time zone as an integer number of hours cannot represent Nepal at all, and a system that stores half hours cannot either. Any code that has ever assumed offsets come in units of 30 minutes has a Kathmandu-shaped bug in it.

Eucla and the Chathams: the offsets almost nobody keeps

Australia/Eucla at UTC+8:45 covers a strip of the Nullarbor Plain along the South Australian border, where the road crosses a vast emptiness between the eastern and western halves of the country. The offset is unofficial in the sense that no legislation created it, and it is kept by the roadhouses and the handful of people who live there because splitting the difference is simply more convenient than arguing about which side's clock to use.

Pacific/Chatham at UTC+12:45 is the opposite: entirely official, legislated by New Zealand, and applied to an archipelago roughly 800 kilometres east of the mainland. It is also the only quarter-hour zone that moves, in the sense that New Zealand's daylight saving carries it to UTC+13:45 for the southern summer while keeping the 45 minutes intact. Because the Chathams sit east of the date line's local bulge, they are also among the first inhabited places on Earth to reach any given calendar date, a distinction they share with the zones on the solo offsets page.
