# The clock

> The clock (De klok in Dutch) is a free browser-based clock and countdown app at https://theclock.online. It offers fullscreen digital, analog and flip clocks, duration timers and event countdowns without an account.

The interface supports English and Dutch. The home page at / shows the default clock without redirecting. First-time visitors see the Minimal analog clock; returning visitors keep their saved clock settings. Its initial HTML is Dutch; in the browser it uses the saved or detected language, and navigating to another tool or Explore adds /en/ or /nl/ to the URL. Changing language in Settings on / updates the clock interface in place. All other public pages use a locale-prefixed URL with one fixed language, regardless of saved preferences or browser language. The clock entry pages are /en/ and /nl/. On a localized page, switching language in Settings opens the corresponding localized URL. Preferences are stored in the browser. Other unprefixed page URLs are not supported.

Clocks use the device's system time, without network or atomic-time calibration. Event countdowns use the device's time zone and the browser's IANA time zone data. Shared event dates are displayed in the recipient's device time zone while preserving the same instant.

Interactive tools require JavaScript. Keep the tab open and the device awake for duration timer sounds; browser audio restrictions and suspended tabs can delay or prevent them.
