Perth time zone
Perth and the rest of Western Australia use Australian Western Standard Time (AWST), UTC+8, all year. The IANA zone is Australia/Perth. It is the same clock time as Singapore, Hong Kong, Beijing and Manila.
Western Australia has voted against daylight saving four times: in 1975, 1984, 1992 and 2009. The last vote, on 16 May 2009, followed a three-summer trial, and 54.56% voted no. Clocks in Perth have not changed since March 2009.
Time difference between the UK, Perth and Sydney
Perth's offset is fixed, but both the UK and eastern Australia change their clocks, so the gap to London and to Sydney moves at different times of year.

| 1 Jan to 28 Mar 2026 | 8 hours ahead | 3 hours ahead |
| 29 Mar to 4 Apr 2026 | 7 hours ahead | 3 hours ahead |

Perth is the easiest Australian city to reach in UK office hours: a UK morning call up to about 10am still lands in the Perth working afternoon during British Summer Time.
Converting the time
9am in London is 4pm in Perth during British Summer Time and 5pm in winter. Events set in eastern Australian time need one more step: the Melbourne Cup, run at 3pm in Melbourne in November, is noon in Perth and 4am in the UK. Use the time zone converter for other times, or the meeting planner to line up a call.
