Three-stage timing · 05:00
Zero-length stages are skipped. Reset before editing stage times.
How it works
Simple by design.
- 01Set green, amber, and red times. A stage may be zero if another stage has time.
- 02Start the total countdown; stages advance automatically from its absolute deadline.
- 03Pause and resume accurately, or reset before editing your stage plan.
- 04At zero, the countdown stops and stays completed. Restart it manually when you are ready.
- 05Green, amber, and red follow your actual stage times. Every mode saves its own countdown.
Questions, answered.
Can a traffic stage have zero seconds?
Yes, if the total is greater than zero. Set green, amber and red separately; zero-length stages are skipped. Pause preserves the current stage. The plan stops after its final stage and only restarts when you press Restart.
Will a countdown restart automatically at zero?
No. A countdown stops at zero and stays completed. To run it again, press Restart yourself; switching pages or refreshing does not start another run.
Will alerts sound if my device sleeps?
Timing catches up from timestamps when the browser resumes. Audio can be delayed or blocked while suspended; keep the page open and the device awake for important alerts.
