A Fully-Featured Online Alarm Clock

Need a reliable way to set an alarm without reaching for your phone? Our Online Alarm Clock is a powerful, browser-based tool that ensures you never miss an important event. Whether you need a wake-up call, a reminder for a meeting, or a timer for a task, this tool has you covered. It's easy to use, highly customizable, and works directly on this page.

How It Works

The alarm clock continuously checks the current time against the alarms you've set. When the time matches, it triggers an audible alarm and a visual notification. Your alarms are saved in your browser's local storage, so they'll be here waiting for you the next time you visit.

Key Features

  • Multiple Alarms: Set as many alarms as you need, each with its own time, label, and sound.
  • Custom Sounds: Choose from a list of built-in alarm tones or upload your own sound file (MP3, WAV, etc.) for a truly personal experience.
  • Repeating Alarms: Set alarms to repeat on specific days of the week, perfect for daily wake-ups or weekly reminders.
  • Snooze Functionality: When an alarm goes off, you can hit the snooze button to get a few extra minutes before it rings again.
  • 12h/24h Format: Toggle between 12-hour and 24-hour time formats to suit your preference.
  • Persistent Storage: Your alarms are saved locally, so you don't have to set them up again every time you open the page.
