Compare the time in Australia, China, and Japan with that in the U.S.

Here are the time zone differences between Australia, China, Japan, and the United States across some major cities:

• Australia: Australia has multiple time zones. For instance, Sydney is in the Australian Eastern Standard Time (AEST) zone, which is typically around 14-16 hours ahead of U.S. Eastern Standard Time (EST) depending on daylight saving time in each country. For example, during U.S. daylight saving time, Sydney is around 14 hours ahead of EST, and during U.S. standard time, it's around 16 hours ahead.
• China: China operates on a single time zone known as China Standard Time (CST), which is 12 to 13 hours ahead of U.S. Eastern Standard Time (EST). For example, during U.S. daylight saving time, China is around 12 hours ahead of EST, and during U.S. standard time, it's around 13 hours ahead.
• Japan: Japan is in Japan Standard Time (JST), which is generally 13 to 14 hours ahead of U.S. Eastern Standard Time (EST). For example, during U.S. daylight saving time, Japan is around 13 hours ahead of EST, and during U.S. standard time, it's around 14 hours ahead.

These time differences might vary slightly due to daylight saving time changes in different countries and regions. It's always advisable to check the current time differences and daylight saving adjustments for accurate timing between these regions as they can change over the years.
