“Alarm Clock” is a very handy application that I recently discovered in one of my favorite sources of Ubuntu software (getdeb.net), it has the following features:

1. Resides in the notification area (and can start minimized, i.e. you can easily configure it to start minimized with Ubuntu)
2. Has many methods of notifications; alarm sound, a simple dialog, and a pop-up in the notification area (what’s called a passive window)
3. Has snooze functionality
4. Has a calendar for saving birthdays.

Here are some screenshots that I took for you:

You can get the application from here, Enjoy 🙂
