Lisbon and Sydney are 9h apart. When it's 9 AM in Lisbon, it's already 6:00 PM in Sydney — meaning Sydney's working day is well underway before Lisbon's morning has properly started.
There is no overlap during standard 9–17 business hours. Every synchronous meeting requires someone to work outside normal hours. The fairest approach is to rotate that burden: one week Lisbon takes the early call, the next week Sydney does. TimeSync's standup planner computes the exact rotation automatically.
For any recurring sync between Lisbon and Sydney, set the calendar invite in one canonical timezone and confirm the other side sees the correct local time. DST transitions can silently shift the effective meeting time by an hour for several weeks without either party noticing until someone is waiting alone on the call.
For truly zero-overlap pairs, the most important investment is async infrastructure: a written daily digest each team can read at the start of their day, a shared decision log so nothing critical gets blocked waiting for a live reply, and a clear escalation path for genuine emergencies. With those in place, most distributed teams find they need far fewer live calls than they assumed.
Lisbon is UTC+1 and Sydney is UTC+10, a difference of 9h. This gap may shift by 1 hour during DST transitions.
There is no overlap during standard 9–17 hours. Consider a rotating schedule or an early/late meeting. TimeSync's standup planner can find the least-painful slot.
Yes. Both cities observe daylight saving time, but on different schedules. Lisbon springs forward on March 29 and Sydney on October 4, so the gap between them shifts by 1 hour during the spring and fall mismatch window.
Lisbon and Sydney have no overlap during standard 9 AM–5 PM business hours.
Under standard 9–5 schedules, no. The 9h gap means the two cities' business days do not overlap. Teams that need synchronous collaboration typically shift one side's hours, rotate the inconvenient slot fairly, or rely on async-first workflows with structured handoffs.
