Sydney is 14 hours ahead of Washington, D.C., according to Timeanddate: Australia time in Sydney is AEST (UTC+10) while Washington uses EDT (UTC−4), creating a 14‑hour difference.
Timeanddate lists Sydney’s time zone as AEST, UTC/GMT +10 hours, and notes that daylight saving in New South Wales ended on Apr 5, 2026. That entry is the basis for the Australia time offset cited here.
Timeanddate also shows Washington, D.C. is on Eastern Daylight Time (EDT), UTC/GMT −4 hours, with U.S. daylight saving having started on Mar 8, 2026. With those UTC offsets, Sydney sits 14 hours ahead of Washington.
That 14‑hour gap matters for scheduling calls, markets and business hours across the two cities: a 9:00 a.m. business hour in Washington is 11:00 p.m. in Sydney on the same calendar day, per the UTC offsets above.
For planners, Timeanddate offers converters and a meeting planner for Sydney and Washington that use those same UTC offsets to calculate cross‑city times.
