Free Online Chess Clock — Tournament-Grade Digital Timer

♟️ What Is an Online Chess Clock?

A chess clock tracks each player's remaining thinking time separately. When you finish your move, you press your clock to stop your timer and start your opponent's. This free digital chess clock replicates that experience accurately in any browser, with millisecond precision powered by requestAnimationFrame.
