Perth does not change its clocks
A fixed offset, all year round
Perth stays on Australian Western Standard Time at UTC+08:00 every day of the year. There is no spring-forward or fall-back here, which puts it with the majority: most of the world's time zones do not observe daylight saving.
That sounds like it makes scheduling simpler, and locally it does — but it introduces a different trap for anyone working with Perth from a country that does change clocks. The offset between you and Perth is not constant: it changes when your clocks move, even though nothing changed here. A recurring call that has run at the same local time for months will shift by an hour, from your side, without anyone editing the invite.
When the gap to Perth 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 Perth:
Singapore (Singapore)
Neither Perth nor Singapore changes its clocks in the next year, so the gap between them stays fixed. One less thing to track.
Tokyo (Japan)
Neither Perth nor Tokyo changes its clocks in the next year, so the gap between them stays fixed. One less thing to track.
Los Angeles (United States)
- From 1 November 2026: Perth is 16 hours ahead of Los Angeles
- From 14 March 2027: Perth is 15 hours ahead of Los Angeles

Places related to Perth
Cities that share a clock, a country, or an offset
On exactly the same clock as Perth
These share the Australia/Perth zone, so they keep the same time as Perth year-round.
Elsewhere in Australia
Australia spans more than one time zone, so these cities are not on Perth's clock — a common source of scheduling errors when people pick a country rather than a city.
Same offset (UTC+08:00), different part of the world
These sit in other countries but keep the same standard offset as Perth (Australian Western Standard Time). They will not necessarily change clocks on the same dates, so the match can be seasonal rather than permanent.
