Countdown Timer is a free Chrome extension developed by lastlegume. As the name suggests, it allows users to set a countdown to a specified date and time.

The extension is easy to use - simply click on the icon located on your addons taskbar and enter the desired date. The countdown will then begin and the extension will display the remaining time until the target date.

Once installed, you can find the Countdown Timer icon under the puzzle piece in the top right corner of Chrome. Clicking on the extension will open a window where you can input the date you want to countdown to. The extension will then calculate and show the proportion of time that has passed between the countdown starting and the target date.
