What is the number of hours of time difference between the U.S. and Sydney, Australia?

Answer by  localgirl808 (405)

Sydney's time zone is 18 hours ahead of Denver's time zone. This means that Sydney is almost a day "ahead" of Denver. For example, when it is 12 noon on January 2 in Denver, it is 6 a.m. on January 3 in Sydney.

The time difference between the US and Australia varies depending on which time zone you're in (Eastern, Central, Mountain time, etc). As a guide, the difference between Eastern Time and the time in Australia is of 12 hours. They're 12 hours ahead.

In August, for example, Denver is 16 hours behind Sydney. However, Australia and the US move in opposite directions for Daylight savings, so in winter it's a 18 hour difference.
