About this tool
Hong Kong to Kolkata Time Converter
Convert time between Hong Kong 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 Hong Kong — this converter shows both cities' clocks live and the exact current time difference between them, adjusted automatically for daylight saving. Hong Kong runs on the Asia/Hong_Kong zone (HKT) 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 Hong Kong time to pin the matching Kolkata time, or press swap to convert the other way. Nothing is uploaded.

Frequently asked questions
What is the time difference between Hong Kong and Kolkata?
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. Hong Kong uses Asia/Hong_Kong and Kolkata uses Asia/Kolkata.
What time is it in Kolkata when it's 9:00 AM in Hong Kong?
Type 9:00 into the Hong Kong 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.
Does this converter handle daylight saving between Hong Kong and Kolkata?
Yes. It uses your browser's own time-zone data (Asia/Hong_Kong for Hong Kong, Asia/Kolkata for Kolkata), which carries each region's daylight-saving rules, so the result stays correct all year.
Can it convert Kolkata time to Hong Kong time as well?
Yes — press the swap button and the converter flips to show Kolkata → Hong Kong, with the same live clocks and time picker.
Is the Hong Kong to Kolkata time conversion accurate and private?
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.
