About this tool
Convert time between Vienna and Prague with live clocks and the current, daylight-saving-aware time difference.
See what time it is in Prague when you know the time in Vienna — this converter shows both cities' clocks live and the exact current time difference between them, adjusted automatically for daylight saving. Vienna runs on the Europe/Vienna zone (CET) and Prague on Europe/Prague (CET); 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 Vienna time to pin the matching Prague time, or press swap to convert the other way. Nothing is uploaded.
Open Vienna to Prague Time Converter on AltFTool — it loads instantly in your browser.
Read the live clocks at the top for the current time in Vienna and Prague.
Type a specific time into the Vienna field to see the matching Prague time and date.
Press swap to convert Prague times to Vienna instead.
The current local time in Vienna and Prague 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 Vienna time to see the exact Prague 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. Vienna uses Europe/Vienna and Prague uses Europe/Prague.
Type 9:00 into the Vienna field above and the converter shows the matching Prague time for today, daylight saving included. It also shows the Prague date in case the time crosses midnight.
Yes. It uses your browser's own time-zone data (Europe/Vienna for Vienna, Europe/Prague for Prague), 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 Prague → Vienna, 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.
