Lyon to Sydney Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Lyon and Sydney don't overlap on the same weekday. Sydney is 8 hours ahead of Lyon.

With some flexibility, there’s a workable window outside standard hours:

• 7 AM–12 PM in Lyon (3 PM–8 PM in Sydney) — suggest 9:00 AM Lyon (5:00 PM Sydney).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

Lyon uses Central European Time (CET, or CEST). To call France, dial +33.

Sydney uses Australian Eastern Time (AEST, or AEDT). To call Australia, dial +61.

Sydney is approximately 10,500 miles east of Lyon.

Both zones observe daylight saving time, but they transition on different dates.

Lyon: next transition on Sunday, October 25, 2026.

Sydney: next transition on Sunday, October 4, 2026.

Lyon and Sydney are in opposite hemispheres, so their clocks change in opposite directions about six months apart — one springs forward while the other falls back. The offset between them therefore shifts twice a year and can swing by up to two hours across the seasons, more than a typical same-hemisphere pair. Recurring meetings will need re-checking after each transition.

See the daylight saving time page for transition dates across every time zone.
