An online digital clock (also called a digital clock online) is a webpage that displays the current time in digits—usually hours, minutes, and often seconds—using your device’s local clock. Unlike a wall clock or phone lock screen, you can leave it fullscreen on a monitor, pin it as a clock tab, or share it in a classroom without installing software. This free digital clock updates once per second, supports fullscreen, and does not require a browser extension or account.
Remove distractions with a single click. Perfect for exams, classrooms, and focus sessions.
