Daymark – Live Day Counter

See exactly how many days have passed since a moment that matters. Daymark turns every new tab into a quiet, continuously updating day counter. Choose a starting date and time, and the display advances in precise decimal days so you can actually see time move. Make the page yours: • Add your own short message • Place the message above, below, left, or right of the counter • Resize the timer and position it in any corner, edge, or the center • Use a solid background color or your own photo • Adjust the image shade for comfortable reading Everything stays on your device. Daymark has no account, analytics, ads, tracking, or external network requests. Your starting moment, text, layout, and optional background image are stored only in Chrome's local extension storage. Daymark replaces Chrome's New Tab page and works offline.
