Time Since... is a free Chrome extension developed by Louis-Charles Biron. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools. This extension allows users to easily and precisely track the amount of time that has passed since they started doing something or since a certain event occurred.

Upon opening the extension page, either by clicking on the icon or using the keyboard shortcut (Ctrl+Shift+L by default), users are greeted with a simple interface. This interface allows them to add events that will be tracked for time.

The concept behind Time Since... is straightforward. Users can set up events and then forget about them. After a few months, they can revisit the extension to see how much time has passed and how things may have changed since. It provides a convenient way to keep track of the passage of time and its impact on various activities.

With its user-friendly interface and precise tracking capabilities, Time Since... makes it easy for users to monitor the time elapsed since specific events. Whether it's tracking personal milestones, project durations, or any other time-sensitive activities, this extension proves to be a useful tool.
