Open Meeting Planner →What Sydney and Dublin have in common is technology; that is the usual reason for a call between them. The gap is 9 hours, with Sydney the one whose clock reads later.
The working week is Monday to Friday on both sides: roughly 09:00–17:30 in Sydney and 09:00–17:30 in Dublin. Watch for Australia Day (26 January) and Anzac Day (25 April) in Sydney and St Patrick's Day (17 March) and Easter Monday (March or April) in Dublin.
There is no hour when both offices are open, only the edges: an early start in Dublin meets a late finish in Sydney. Alternate who stretches, and keep those calls short. Both cities change their clocks, on different dates, so the gap is an hour off for a few weeks each spring and autumn.
Sydney is 9 hours ahead of Dublin. The gap changes by an hour around the clock changes.
There is no hour when both offices are open. The closest is early morning in Dublin against the end of the day in Sydney; alternate which side takes the awkward slot.
Alternate. A standing call that is always 07:00 for Dublin or always 19:00 for Sydney is resented within a month; rotating it keeps both sides in the room.
For the working day, yes — the gap is not wide enough to push office hours across midnight.
