A Large Online Digital Clock
This free digital clock shows your device's current time in big, easy-to-read digits. Put it on a projector, whiteboard, spare monitor, or tablet — in fullscreen it scales to fill the screen and stays crisp across a whole room. It follows the site's light or dark theme (the ☾ toggle in the header), so it looks right in a bright classroom or a dim bedroom.
12-Hour or 24-Hour
Toggle 24-hour for military-style time (00:00–23:59), or leave it off for a standard 12-hour clock with AM/PM. You can also hide the seconds or the date for a cleaner face.
