Build countdown timers, flash sale clocks, or session timeouts in React. useCountdown returns the current count plus startCountdown, stopCountdown, and resetCountdown controls. Configure start/stop values, interval speed (default 1000ms), and direction (count up or down). All callbacks are memoized. Auto-stops when reaching target. SSR safe with no window access until started. Perfect for Next.js App Router, product launches, quiz timers, or any time-limited UI.
