Australian Western Daylight Time (AWDT)

Introduction

Australian Western Daylight Time (AWDT) is the daylight saving time zone that was historically used in Western Australia during the summer months. It operates nine hours ahead of Coordinated Universal Time (UTC+09:00). This time zone was used to make better use of daylight during the longer days of summer, helping to save energy and provide more daylight in the evening.

Time Zone History

The history of Australian Western Daylight Time is closely tied to Australia's efforts to manage energy consumption and make better use of natural daylight. Daylight saving time was first introduced in Australia during World War I to conserve energy. Western Australia has experimented with daylight saving time several times, but it has not been observed since 2009 following a referendum in which the majority of voters opposed its continuation.
