Shot Clock: 24-Second Basketball Shot Clock Online
Run a basketball shot clock in the browser: 24 seconds with a 14-second reset, or 30 for college rules, start and stop with the space bar, tenths of a second under five seconds, a horn at zero, and full screen.
Shot Clock: 24-Second Basketball Shot Clock Online: The clock counts down from the device clock, so it stays exact, and shows whole seconds rounded up, as arena clocks do, then tenths below five seconds. At zero it sounds a horn and stops. Resetting while it runs keeps it running from the new time. Runs 100% locally in your browser with zero server file uploads.
