Open Meeting Planner →Both cities run on finance, so most calls between Sydney and Buenos Aires are between people in the same trade. Put simply, when it is 09:00 in Buenos Aires it is already 14 hours later in Sydney, on the following date.
Both cities work Monday to Friday, Sydney typically 09:00–17:30 and Buenos Aires 09:00–18:00 local time. On the Sydney side the dates that break a schedule are Australia Day (26 January) and Anzac Day (25 April); on the Buenos Aires side, Carnival (Monday and Tuesday in February or March) and May Revolution Day (25 May).
There is no hour when both offices are open, only the edges: an early start in Buenos Aires meets a late finish in Sydney. Alternate who stretches, and keep those calls short. Only Sydney changes its clocks, so the gap shifts by an hour twice a year while Buenos Aires stays put.
Sydney is 14 hours ahead of Buenos Aires. 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 Buenos Aires 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 Buenos Aires or always 19:00 for Sydney is resented within a month; rotating it keeps both sides in the room.
Not always. At 09:00 in Buenos Aires it is already the next calendar day in Sydney, so every invitation should carry the date in both cities.
