AEDT vs CET — cities and working rhythm
Australia's east coast — Sydney (financial), Melbourne (corporate HQ / media), Brisbane (mining / education). Business hours 9 AM – 5 PM AET. Summer: AEDT (UTC+11); winter: AEST (UTC+10). Brisbane stays on AEST year-round — so Sydney and Brisbane are 1 h apart in summer, same in winter. Almost entirely opposite of European hours.
Most of continental Europe — DACH, Benelux, France, Iberia, Nordics (except Finland), Poland, Czech Republic. Business hours 9 AM – 5:30 PM CET, with a longer lunch (12:30 – 2 PM) in southern countries. Winter: CET (UTC+1); summer: CEST (UTC+2). Big lag against North America — early morning CET overlaps late night ET.
Time gap: CET is 10.0 hours behind AEDT (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
