What this tool helps you find
Choose a target date and optional local time. The remaining days, hours, minutes, and seconds update in your browser once per second.
Formula
Remaining time = target timestamp − current timestamp.
Worked example
A target 1 day and 2 hours away displays 1 day, 2 hours, 0 minutes, and 0 seconds.
Common mistake
The chosen time is interpreted in the device’s local time zone. A target that has already passed shows that it has passed.
When to use it
Track time remaining before an event, deadline, trip, or personal milestone.
Questions and answers
