EDT vs AEST — cities and working rhythm
US East Coast summer offset (mid-March to early November), UTC-4. The narrower gap to Europe (only 4 h during northern-hemisphere summer) means early-morning EU meetings align with reasonable East Coast times.
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.
Time gap: AEST is 14.0 hours ahead of EDT (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
