When the difference changes

Indochina 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:

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

Daylight saving

Indochina Time

No clock changes

Indochina Time stays on ICT all year, so its offset from UTC never moves.

Australian Eastern Time

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on AEDT after that.

Scheduling between the two

Working hours overlap from 9:00 am to 3:00 pm ICT, which is 12:00 pm to 6:00 pm AEST. Anything inside that window falls in the normal working day at both ends.

Indochina Time (ICT) is used in Thailand, Vietnam, Cambodia and Laos

Australian Eastern Time (AEST) is used in Melbourne, Canberra and Brisbane. Queensland stays on AEST all year while the southern states move to AEDT.
