"On this day" is a Chrome extension that transforms your new tab page into an engaging source of daily fun facts. This program offers a unique experience by replacing the standard new tab page with a random background image every day. Additionally, it provides a button that, when clicked, reveals an interesting fact about the current date.

With "On this day," users can start their browsing sessions with a touch of curiosity and knowledge. The combination of visually appealing backgrounds and daily facts adds an element of surprise and learning to the otherwise mundane task of opening a new tab in the browser.
