Online Clock

Welcome to Time.now, the ultimate Online Clock for professionals, educators, and anyone who values precision. Whether you are managing a remote team across different time zones or need a distraction-free exam timer, our tool adapts to your needs with an exact, full-screen display.

Why use this Online Clock?

In a digital-first world, having a reliable digital clock is crucial. This tool pulls time directly from atomic-synced servers (coordinated via your device's system time), accounting for network latency to provide the most accurate display possible in a web browser. It serves as a perfect reference for setting other watches or simply keeping on task.

Key Features of our Full Screen Clock

  • Atomic Precision: Synchronized with browser time standards to ensure you are always on schedule.
  • Immersive Mode: The interface automatically hides controls after inactivity, giving you a clean, full screen clock view. Simply move your mouse to bring them back.
  • Global Timezones: Select any city or timezone from the settings menu to track time anywhere in the world.
  • Custom Themes: Choose from our beautiful pre-configured gradients or use a custom color/image background to personalize your online clock.
  • Share & Customize: You can create and share the clock: customize an existing theme, save it, and then share the clock.

How to Use the Online Clock

We designed this tool to be intuitive, but it is packed with hidden customization features. Here is how to get the most out of it:

1. The Control Dock

At the bottom of the screen resides the main control dock. If you do not see it, simply move your mouse or tap the screen. The dock automatically fades away after 4 seconds of inactivity to keep your view unobstructed.

  • Zoom (+ / -): Use these buttons to increase or decrease the font size of the time display.
  • Settings (Sliders Icon): Opens the configuration panel where you can toggle Seconds, 12/24-hour format, and the Date display.
  • Fullscreen (Arrows Icon): expands the browser to fill your entire monitor, perfect for use as a screensaver or classroom display.

2. Customizing Themes & Backgrounds

Inside the Settings menu, you will find the "Quick Themes" grid. Click any swatch to instantly change the look, from OLED-friendly black to "Matrix" code or "Cyber" gradients.

Pro Tip: You can set a custom background by pasting a direct image URL into the "Custom Look" input field in the settings.

3. Sharing Your Time

Need to send a countdown or a specific timezone clock to a colleague? Configure the clock exactly how you want it (e.g., select "Tokyo" time and "12-hour" format), then click the Share Icon. This generates a unique link that preserves your settings for the recipient.
