Perth never changes its clocks
Perth stays on UTC+08:00 all year round. This is worth being careful about rather than relaxed about: the gap between Perth and a city that does observe daylight saving still moves twice a year, because the other end moved. A recurring call can drift by an hour without anything changing here at all.
Time difference from Perth
Where a range is shown, the gap genuinely changes during the year. That is not rounding or hedging — it is two governments moving their clocks on different weekends.
| City | Difference now | Across the year |
|---|---|---|
| London | 7 hours behind | −8h / −7h |
| New York | 12 hours behind | −13h / −12h |
| Los Angeles | 15 hours behind | −16h / −15h |
| Chicago | 13 hours behind | −14h / −13h |
| Toronto | 12 hours behind | −13h / −12h |
| Paris | 6 hours behind | −7h / −6h |
| Berlin | 6 hours behind | −7h / −6h |
| Dubai | 4 hours behind | constant |
| Mumbai | 2 hours 30 minutes behind | constant |
| Singapore | the same time | constant |

Daylight in Perth through the year
From about 10.1 hours in June to 14.3 hours in December. This is the part a plain clock leaves out: 17:00 is a bright evening in one month and long dark in another.

| January | 05:14 | 19:08 | 13h 54m |
| February | 05:43 | 18:46 | 13h 3m |
| March | 06:04 | 18:12 | 12h 8m |
| April | 06:24 | 17:34 | 11h 10m |
| May | 06:45 | 17:08 | 10h 23m |
| June | 07:00 | 17:04 | 10h 4m |
| July | 06:57 | 17:17 | 10h 20m |
| August | 06:32 | 17:37 | 11h 5m |
| September | 05:53 | 17:55 | 12h 2m |
| October | 05:15 | 18:16 | 13h 1m |
| November | 04:51 | 18:43 | 13h 52m |
| December | 04:51 | 19:06 | 14h 15m |
Daylight length is accurate. The clock times of sunrise and sunset assume each city sits at the centre of its time zone, which can put them up to about an hour and a quarter out for places near a zone's edge — Madrid being the standard example. Day length is unaffected.
Questions
About time in Perth
What time zone is Perth in?
Perth uses the IANA time zone Australia/Perth, a fixed UTC+08:00 with no daylight saving.
Does Perth observe daylight saving time?
No. Perth stays on UTC+08:00 all year. That does not mean the gap between Perth and other cities is fixed, though: when a city that does observe daylight saving changes its clocks, the difference between you and them moves even though nothing changed here.
Why does the time difference to Perth keep changing?
Because the two places do not change their clocks on the same weekend, and in opposite hemispheres they change in opposite directions. London is a clear example: it sits 8 hours behind, then 7 hours behind across the year rather than one fixed distance.
How much daylight does Perth get?
Around 14.3 hours at the longest, in December, and about 10.1 hours at the shortest, in June. The table on this page lists sunrise and sunset through the year. Times are calculated from Perth's latitude of -31.95° and are approximate to within about an hour for cities that sit well away from the centre of their time zone.
