About s-clock.com

s-clock.com is a browser-based collection of time tools. It is built for simple daily workflows such as setting an online alarm, running a countdown timer, tracking stopwatch laps, comparing world time zones, and checking upcoming holiday countdowns.

What the site provides

• Online alarm clock with labels, presets, and browser audio testing.
• Countdown timer with common presets and configurable end behavior.
• Stopwatch with millisecond display and lap history saved locally.
• World clock with global IANA time zone selection.
• Holiday countdowns for common holidays in the United States, United Kingdom, Australia, and Canada.

How it works

The tools run in your browser and use localStorage for preferences and saved lists. Alarms and timers are intended for active browser sessions and do not continue after the tab or browser is closed.
