When Newcastle changes its clocks
Newcastle is one of the places that still shifts its clocks twice a year
Newcastle keeps Australian Eastern Standard Time at UTC+10:00 for most of the year, and moves to Australian Eastern Daylight Time at UTC+11:00 during its southern-hemisphere summer. The shift is 1 hour.
Because Newcastle is in the southern hemisphere, its summer time runs across the new year rather than through the middle of it. When northern cities move forward in March, Newcastle is moving back — so the gap between Newcastle and Europe or North America changes by two hours over the year, not one.
Next change
4 April 2027 — clocks move back by 1 hour, from UTC+11:00 to UTC+10:00.
Upcoming transition dates
- 5 April 2026 — back to UTC+10:00
- 4 October 2026 — forward to UTC+11:00

- 3 October 2027 — forward to UTC+11:00
- 2 April 2028 — back to UTC+10:00

When the gap to Newcastle changes
Dates in the next year where the difference shifts, by counterpart city
The difference between two cities is not a constant. It changes whenever either side moves its clocks — and because regions switch on different dates, there are short windows each year when the usual gap is wrong. These are the dates that matter for Newcastle:
Singapore (Singapore)
- From 4 April 2027: Newcastle is 2 hours ahead of Singapore
- From 3 October 2027: Newcastle is 3 hours ahead of Singapore
Tokyo (Japan)

Clock time versus solar time
Newcastle's clock is unusually well matched to the sun: local noon falls within 7 minutes of the moment the sun is actually overhead. Most cities sit further out, because time zones follow borders rather than longitude.
During summer time that gap widens to 53 minutes ahead of the sun, which is the whole point of the exercise — shifting daylight into the evening.
How Newcastle's clock got here

When the clocks change here
Clocks go forward on the first Sunday in October, a rule the tzdb has applied since 2008.
It changed once:
- 2008from last Sunday in October to first Sunday in October
Before any of this, Newcastle kept local mean time — solar noon by definition — at UTC+10:05, until February 1895. Standard time zones were an attempt to replace that with something people could agree on, and the Newcastle clock still carries the residue of that original figure.
Every date above is a record in the IANA Time Zone Database, not an estimate. The database is maintained by volunteers who track official announcements; if a government changes its rules, these figures change with it.

Places related to Newcastle
Cities that share a clock, a country, or an offset
On exactly the same clock as Newcastle
These share the Australia/Sydney zone, so they keep the same time as Newcastle and change their clocks on the same dates.
Elsewhere in Australia
Australia spans more than one time zone, so these cities are not on Newcastle's clock — a common source of scheduling errors when people pick a country rather than a city.
Same offset (UTC+10:00), different part of the world
These sit in other countries but keep the same standard offset as Newcastle (Australian Eastern Standard Time). They will not necessarily change clocks on the same dates, so the match can be seasonal rather than permanent.
