Open Meeting Planner →Sydney's finance and mining head offices and Istanbul's textiles and construction are different worlds, which is exactly why they call each other. Put simply, when it is 09:00 in Istanbul it is already 8 hours later in Sydney.
The working week is Monday to Friday on both sides: roughly 09:00–17:30 in Sydney and 09:00–18:00 in Istanbul. Watch for Australia Day (26 January) and Anzac Day (25 April) in Sydney and Ramadan Feast (end of Ramadan, three days) and Sacrifice Feast (four days, roughly 70 days later) in Istanbul.
The office days never overlap; the workable slots are Istanbul's early morning against Sydney's evening. Rotate the inconvenience rather than fixing it on one side. Only Sydney changes its clocks, so the gap shifts by an hour twice a year while Istanbul stays put.
Sydney is 8 hours ahead of Istanbul. 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 Istanbul 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 Istanbul 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.
