Countdown to a future date
Choose a target date and time to see remaining days, hours, minutes, and seconds. It is designed for events or deadlines tied to a calendar instant.
Drift-free updates
The countdown recalculates against actual time on every update. After a background pause, it immediately restores the correct remaining duration.
