Convert JST to AEST
Japan Standard Time (JST) to Australian Eastern Time (AEST)
Japan-Australia trade is significant in mining, energy, and agriculture, with Tokyo and Sydney offices frequently coordinating. The 1-hour gap during AEST makes real-time collaboration effortless, but Australia's shift to AEDT in October widens it to 2 hours -- and Japan does not observe DST, so teams must adjust one-directionally.

Scheduling Tips
- Schedule freely during standard business hours -- a 1-2 hour offset means 9 AM-5 PM overlaps almost entirely in both cities.
- During AEDT (October-April), keep in mind that 9:00 AM Tokyo is 11:00 AM Sydney. Push meetings slightly earlier in JST to stay within the Sydney morning.
- For cross-market trading or live data handoffs, align on AEST/AEDT calendar labels to avoid confusion during the October and April DST transitions.
- Japan's fixed schedule is the anchor -- let Australia-side participants adjust their calendars each DST switch rather than moving the meeting for both.
