# About This Calculator
A Countdown Timer is a simple but effective time management tool. By setting a fixed deadline for a task, you can leverage "Parkinson's Law"—the idea that work expands to fill the time available for its completion.
Whether you're using it for the Pomodoro Technique, timing a soft-boiled egg, or presiding over a debate, a clear visual countdown helps maintain focus and urgency.
