Best time to call Dublin from Sydney (and vice versa)

With 9 hours between them there is no hour at which Sydney and Dublin are both inside a 9:00–17:00 working day. Teams split across these two cities usually alternate the sacrifice: one week the meeting lands early (7:00–8:00) in Dublin and late (18:00–19:00) in the other city, the next week the other way round. The Timezone Matcher grid shades exactly those compromise hours.

The two time zones

Sydney — Australia/Sydney

Sydney uses Australian Eastern Time: UTC+10 in winter (AEST) and UTC+11 in summer (AEDT), from the first Sunday of October to the first Sunday of April — opposite to the northern hemisphere.

Dublin — Europe/Dublin

Dublin follows the same clock as London (UTC+0 in winter, UTC+1 in summer) — the European base for many US tech companies precisely because of its 5-hour gap with New York.
