About this tool
Convert time between Osaka and Adelaide with live clocks and the current, daylight-saving-aware time difference.
See what time it is in Adelaide when you know the time in Osaka — this converter shows both cities' clocks live and the exact current time difference between them, adjusted automatically for daylight saving. Osaka runs on the Asia/Tokyo zone (JST) and Adelaide on Australia/Adelaide (ACT); the tool reads your browser's own time-zone data, so the offset is always right even across the days each city changes its clocks. Type any Osaka time to pin the matching Adelaide time, or press swap to convert the other way. Nothing is uploaded.
Open Osaka to Adelaide Time Converter on AltFTool — it loads instantly in your browser.
Read the live clocks at the top for the current time in Osaka and Adelaide.
Type a specific time into the Osaka field to see the matching Adelaide time and date.
Press swap to convert Adelaide times to Osaka instead.
The current local time in Osaka and Adelaide updates every second, with each city's UTC offset and abbreviation shown.
Offsets come from the browser's IANA time-zone database, so the difference is correct on either side of a daylight-saving change — no stale table.
Enter a specific Osaka time to see the exact Adelaide time for today, including the date if the conversion crosses midnight.
It runs entirely in your browser — no account, and no times are sent anywhere.
It can change through the year because one or both cities observe daylight saving, so the converter above shows the current difference live rather than a fixed number. Osaka uses Asia/Tokyo and Adelaide uses Australia/Adelaide.
Type 9:00 into the Osaka field above and the converter shows the matching Adelaide time for today, daylight saving included. It also shows the Adelaide date in case the time crosses midnight.
Yes. It uses your browser's own time-zone data (Asia/Tokyo for Osaka, Australia/Adelaide for Adelaide), which carries each region's daylight-saving rules, so the result stays correct all year.
Yes — press the swap button and the converter flips to show Adelaide → Osaka, with the same live clocks and time picker.
It relies on the standard IANA time-zone database built into your browser, not an approximation, and makes no network calls, so your times stay on your device.
