MEETING PLANNER
hover a column · click to lockSydney is 8 hours ahead of Amsterdam. Amsterdam runs on Europe/Amsterdam (UTC+2); Sydney runs on Australia/Sydney (UTC+10). The difference is measured right now; it can shift by one hour during daylight-saving-time transitions.
Both Amsterdam and Sydney observe daylight saving time, but their transition dates are not identical. Amsterdam shifts between CET (UTC+1) and CEST (UTC+2); Sydney shifts between AEST (UTC+10) and AEDT (UTC+11). The difference between them stays close to 9 hours across most of the year, with short mismatch windows around each city’s transition when the gap briefly widens or narrows by an hour.
Standard 9-to-5 business hours in Amsterdam and Sydney do not overlap. Teams operating across this pair either stretch their schedules — an early-morning call from the westward city lands as an evening call in the eastward one — or rely fully on asynchronous tools. Scheduled windows at the edges (first thing for one side, last thing for the other) are the usual compromise, with one side absorbing the unsocial-hours cost this week and the other side next week.
When planning recurring meetings across Amsterdam and Sydney, pin them to one city’s local time rather than UTC or the other city’s clock. That way, the meeting time stays stable for the person anchoring the schedule, and the other side absorbs the one-hour drift during DST transitions. The alternative — a meeting pinned to the non-DST city — means the DST city sees the meeting time “move” twice a year, which is how recurring calendar invites end up at 7am on someone’s calendar in October.
