Poker tournament clock

Run custom blind levels and breaks with pause, reload-safe local storage and portable JSON snapshots.

Used when Custom is selected. One level per line: small blind,big blind,ante,minutes. A break is break,minutes. You can also paste exported schedule JSON. Big blinds may repeat but cannot decrease; every duration must be positive.

Build a schedule to start

20:00

The clock saves elapsed time against the real clock when running, so reloads and background tabs count correctly. Paused snapshots stay paused. Export the JSON to move it manually to another device. Clock state stays local; no service is contacted.

How this tool works

Generated or imported schedules use elapsed time, including breaks. A versioned local snapshot stores elapsed time, running state and epoch time; reload restores a running clock including time away, while paused clocks stay paused. Export and manually import the JSON to move a clock to another device. Storage can be switched off or cleared. Sharing is a snapshot, not a synchronised online room.

Everything runs on your device. Inputs are not uploaded. The tournament clock can save its schedule and time locally, with a clear control; other inputs are not saved. Export anything you want to keep before leaving the page. Study tools are for practice between sessions; check your poker provider's rules.
