Time difference between Dublin and Sydney

Sydney is 9 hours ahead of Dublin

Dublin, Ireland is UTC · Sydney, Australia is UTC+10 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Dublin goes forward on the last Sunday in March and back on the last Sunday in October and Sydney goes forward on the first Sunday in October and back on the first Sunday in April.

These two are in opposite hemispheres, so their summers do not overlap: Dublin is on summer time roughly when Sydney is not. The gap does not wobble by an hour around a settled figure — it swings between 9 hours and 11 hours and spends a good part of the year at each. There is no single right answer to give a calendar, which is why a recurring meeting between them is worth setting in one city's local time and letting the other side see it move.

When they can both be at their desks

Nine-to-five in Dublin and nine-to-five in Sydney do not overlap at all. With 9 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
