What is the time difference between Tokyo and Sydney?

Sydney is ahead of Tokyo by 2 hours during Australian Daylight Saving Time (AEDT, UTC+11, roughly October to April) and 1 hour ahead during Australian Standard Time (AEST, UTC+10, roughly April to October). Tokyo stays on JST (UTC+9) all year and does not observe DST.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished DST in 1952 and has not used it since. Tokyo stays on JST (UTC+9) all year. Only Sydney shifts its clocks, which is why the Tokyo-Sydney gap alternates between 1 and 2 hours.

When does Sydney switch between AEDT and AEST?

New South Wales moves clocks forward on the first Sunday in October at 02:00 AEST, entering AEDT (UTC+11). Clocks fall back on the first Sunday in April at 03:00 AEDT, returning to AEST (UTC+10).

What are the best meeting times when calling from Tokyo to Sydney?

Both cities share reasonable business-hours overlap. Tokyo at 08:00–17:00 JST maps to Sydney at 10:00–19:00 AEDT (in Australian summer) or 09:00–18:00 AEST (in winter). Mid-morning Tokyo time is typically the best window.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

JST stands for Japan Standard Time. It is UTC+9, used across all of Japan year-round. There is no Japan Daylight Saving Time designation because Japan does not observe DST.

Summary

This tool displays the live current time in both Tokyo (Asia/Tokyo — JST, UTC+9 year-round, no DST) and Sydney (Australia/Sydney — AEDT UTC+11 in summer, AEST UTC+10 in winter) side by side. Tokyo never observes Daylight Saving Time, while Sydney shifts clocks twice a year. The offset between the two cities is either +2 hours (Tokyo behind Sydney in Australian summer, AEDT) or +1 hour (Tokyo behind Sydney in Australian winter, AEST). Use this tool to schedule calls between Japan and New South Wales, coordinate remote teams, or plan Asia-Pacific cross-border meetings.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Asia/Tokyo time (JST, UTC+9) using the IANA timezone database built into modern browsers.
The same moment is converted to Australia/Sydney time (AEDT or AEST depending on the season).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — Tokyo time, Sydney time, and the offset — refresh every second.
When Sydney switches between AEDT and AEST, the displayed offset adjusts automatically.
