When is the best time for a meeting between EST and ACST?

Because EST and ACST are separated by 14.5 hours, standard 9:00 AM – 5:00 PM business hours do not directly overlap. The most practical collaboration times are early morning slots or asynchronous communication.

Do clocks shift for Daylight Saving Time in EST or ACST?

Both EST and ACST observe Daylight Saving Time. When transition dates differ (such as North America in early March vs. Europe in late March), the gap temporarily shifts by 1 hour for several weeks each spring and autumn.
