About these two clocks

EST — Eastern Time. Used in New York, Toronto, Miami, Atlanta. Strictly, EST is the winter name; from March to November the same clocks show EDT (UTC−4). This page follows the clocks, so summer dates use EDT.

AEST — Australian Eastern Time. Used in Sydney, Melbourne, Canberra (Brisbane stays on AEST all year). AEST is the winter name; from early October to early April Sydney clocks run on AEDT (UTC+11). Southern-hemisphere summer means the switch happens in the opposite months to the US and Europe.

All figures on this page come from the IANA time zone database (the same data your phone and laptop use), evaluated for the date in question. Abbreviations are ambiguous — “IST” also means Irish or Israel Standard Time, and “CST” is China Standard Time in Asia — so this page uses America/New_York and Australia/Sydney explicitly.
