About EDT
Eastern Daylight Time (EDT) is UTC−4. It is used in New York, Toronto, Miami and Atlanta from March to November.
Eastern Daylight Time is UTC−4, the summer clock for New York, Toronto, Miami and Atlanta, running from the second Sunday in March to the first Sunday in November. Those dates are US law and do not match Europe's, which changes on the last Sundays of March and October — so for two weeks in March and one in late October the gap between New York and London is an hour different from its usual five.
About ACDT
Australian Central Daylight Time (ACDT) is UTC+10:30. It is used in Adelaide in summer.
Australian Central Daylight Time is UTC+10:30, what South Australia keeps from October to April. Darwin stays on ACST through the summer, so for those months two cities in the same nominal zone are an hour apart — the only reason to be precise about which of the two abbreviations a meeting invitation carries.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on EDT switches to EST (UTC−5) from November to March. So the 14.5-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.
ACDT does not shift, so the whole change comes from one side. A recurring meeting fixed in ACDT will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
Frequently asked questions
What time is 9:00 AM EDT in ACDT?
9:00 AM EDT is 11:30 PM ACDT.
Is ACDT ahead of EDT?
ACDT is 14 hours 30 minutes ahead of EDT.
Which time zone does this use?
EDT is UTC−4 and ACDT is UTC+10:30. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
