Countdown and multi-timer dashboard
CalculateExperimentalLimited support. Verify anything critical.
A multi-timer dashboard tracks several independent countdowns in the same browser tab, including a one-click 25-minute Pomodoro focus interval. Each timer has a persistent text label, remaining time, pause or resume control, and a removal button, so the dashboard works without relying on colour or sound. Timing uses the target end instant rather than decrementing a counter, reducing drift when the tab is temporarily throttled.

How to use Countdown and multi-timer dashboard
Multiple clocks, one view
Use names such as Focus, Export, Meeting, or Break to keep parallel work visible. Every countdown can be paused or removed independently.
Timing limitations
The target timestamp preserves elapsed time when a tab is throttled, but the display may refresh late. Keep a system alarm for deadlines that must not be missed.

Frequently asked questions
Will timers survive a page reload?
No. This experimental version intentionally keeps state only in the current page session.
