About EST (Eastern Standard Time)
Eastern Standard Time (EST) is observed during the winter months in the eastern part of North America. It covers 23 US states and parts of Canada including Ontario and Quebec. EST is the most populous time zone in the United States, home to major financial centers like New York City and global organizations headquartered in Washington D.C.

About ACST (Australian Central Standard Time)
Australian Central Standard Time (ACST) is the half-hour offset of UTC+09:30 used across South Australia and the Northern Territory, taking in Adelaide and Darwin. South Australia moves to Australian Central Daylight Time (ACDT, UTC+10:30) from the first Sunday in October to the first Sunday in April, but the Northern Territory does not observe daylight saving — so Adelaide and Darwin sit 30 minutes apart in summer and level with each other in winter. The half-hour offset means Adelaide is 30 minutes behind Sydney in winter and level with it during daylight saving, which regularly catches out travellers and meeting planners.
