Does the difference between Tokyo and Sydney change during the year?

From	Until	Sydney vs Tokyo
January 1	April 4	+2 h
April 4	October 3	+1 h

The highlighted row is the current period. Every date comes from each zone's official rules, not from a hand-typed table.

Best time to call Sydney from Tokyo (and vice versa)

The window in which both cities are inside their 9:00–17:00 working day runs from 09:00 to 16:00 in Tokyo, which is 10:00 to 17:00 in Sydney: 7 hours of overlap per day. For a call that disturbs nobody, aim for the middle of that window.

Outside that window, the practical rule: mornings in Sydney are afternoons in Tokyo. Avoid any hour that falls before 8:00 or after 21:00 in either city.

The two time zones

Tokyo — Asia/Tokyo

Tokyo keeps Japan Standard Time (JST), a fixed UTC+9 with no daylight saving. Japan and South Korea share the offset, so Tokyo and Seoul are always on the same clock.

Sydney — Australia/Sydney

Sydney uses Australian Eastern Time: UTC+10 in winter (AEST) and UTC+11 in summer (AEDT), from the first Sunday of October to the first Sunday of April — opposite to the northern hemisphere.
