If it 6pm EST in us what time is Australia?

To calculate the time in Australia when it is 6pm EST in the United States, you need to consider the time difference between the two locations. Eastern Standard Time (EST) is 14 hours behind Australian Eastern Standard Time (AEST). Therefore, when it is 6pm EST in the US, it is:

6pm EST + 14 hours = 8am AEST the next day in Australia.
