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