When the difference changes

Western Indonesian Time and Australian Eastern Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

Now – October 3, 2026Australian Eastern Time is 3 hours ahead
October 3, 2026 – April 3, 2027Australian Eastern Time is 4 hours ahead
April 3, 2027 – October 2, 2027Australian Eastern Time is 3 hours ahead
October 2, 2027 – onwardsAustralian Eastern Time is 4 hours ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.
