A simple clock for India

How it works

The clock runs in your browser, using your device time and time zone settings. India’s display uses the Asia/Kolkata time zone. Each tick reads the device clock again. Returning to the page also updates the display.

We do not check your device against an external time server. For time-critical work, verify your device’s clock and use an appropriate synchronized time source.

If the browser cannot read your time or time zone, the page shows an error instead of leaving an old time on screen. Check your device settings, then use “Try again”. If the live clock does not load at all, allow JavaScript and reload the page.

Privacy and storage

Your device time and detected time zone are processed in your browser. The clock does not request your location or send its displayed time, detected time zone, or format preference to a server.

The only preference stored by the site is your 12/24-hour choice, in this browser’s local storage. The clock still works when storage is blocked. You can remove that preference by clearing this site’s browser data.

This version uses Cloudflare Web Analytics on the published site to measure page views, referring sites and loading performance. The analytics beacon sends page and referrer URLs and browser performance measurements to Cloudflare; it does not use cookies or collect the clock’s format choice. Page views are not a count of completed time checks. Blocking analytics does not stop the clock.

There is no advertising or account system. Cloudflare also hosts the site and receives normal web requests, which include information such as your IP address and browser headers. See Cloudflare’s privacy policy.
