Daylight saving time
Both zones observe daylight saving time, but they transition on different dates.
Sydney: next transition on Sunday, October 4, 2026.
Athens: next transition on Sunday, October 25, 2026.
Sydney and Athens 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.
