AEST vs CET — cities and working rhythm
Australia's east-coast winter offset (April to October), UTC+10. Brisbane stays on AEST year-round since Queensland has no DST. Big gap with Europe (8-10 h ahead) and North America (14-17 h ahead) — often faster to just email.
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 9.0 hours behind AEST (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
