What is 1 AM EST in AEST?

Does the answer change during the year?

Yes. Eastern Time and Australian Eastern Time don't change their clocks on the same dates, so over the next 12 months:

• October 14 to October 31: 1 AM EST = 4 PM AEST
• November 1 to March 13: 1 AM EST = 5 PM AEST
• March 14 to April 3: 1 AM EST = 4 PM AEST
• April 4 to October 2: 1 AM EST = 3 PM AEST
• October 3 to October 13: 1 AM EST = 4 PM AEST

Eastern Time switches between EST and EDT for daylight saving time; people often say EST all year. Australian Eastern Time switches between AEST and AEDT for daylight saving time; people often say AEST all year.
