Countdown Timer
Set a target date and time to see how much time remains. The countdown refreshes every second in UTC.
Enter a target date and time to start the countdown.
How it works
The target date and time are interpreted as UTC. Remaining time is computed from the current UTC instant and shown as days, hours, minutes, and seconds. When the target has passed, all values read zero.
Use this for launches, deadlines, and events. For the elapsed span between two past or future moments, use the Date Difference Calculator. For calendar days only, use Days Between Dates.
