New South Wales operates on Australian Eastern Standard Time (AEST) during winter months, which is 10 hours ahead of Coordinated Universal Time (UTC+10). During daylight saving time, observed from the first Sunday in October to the first Sunday in April, New South Wales switches to Australian Eastern Daylight Time (AEDT), which is UTC+11.
Major cities in New South Wales including Sydney, Newcastle, Wollongong, and the Central Coast all follow the same timezone. Sydney, the state capital and Australia's largest city, serves as a major financial hub for the Asia-Pacific region.
New South Wales was the first Australian colony established in 1788 and is home to the Sydney Opera House, one of the most iconic buildings in the world. When it's 9 AM in Sydney, it's 11 PM the previous day in London (during AEDT) and 6 PM the previous day in New York.
