About these time zones
Eastern Standard Time (EST)
Eastern Standard Time (EST) is UTC-5. Most places on Eastern Time use EST only in winter; from the second Sunday in March to the first Sunday in November they observe Eastern Daylight Time (EDT, UTC-4). People often write “EST” all year when they mean Eastern Time, so check which one is in effect.
Australian Eastern Standard Time (AEST)
Australian Eastern Standard Time (AEST) is UTC+10. New South Wales, Victoria, Tasmania and the ACT use AEST in winter and Australian Eastern Daylight Time (AEDT, UTC+11) from the first Sunday in October to the first Sunday in April. Queensland stays on AEST all year.
