Do you ever find yourself wondering how many minutes remain before lunch? Or how many minutes you have until class begins? After installing this extension, you can easily and quickly open an interactive countdown timer that shows this information and more. This extension accompanies Period Countdown (web application located at periods.io). The website and extension interact seamlessly — thus, when you change a preference on the full website (like a period name or theme), the changes will immediately propagate to the extension.
