Australian Central Daylight Time (ACDT)

Introduction

Australian Central Daylight Time (ACDT) is the daylight saving time zone used in parts of Australia during the summer months. It operates ten and a half hours ahead of Coordinated Universal Time (UTC+10:30). This time zone is essential for making 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 Central 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. Since then, the practice has been implemented intermittently and is now a regular part of the timekeeping system in many regions.
