Frequently Asked Questions
How does the Countdown to Date work?
The tool parses your target date and time into a millisecond epoch via new Date().getTime(), then subtracts the current time (Date.now(), updated every second). The raw millisecond difference is broken into days, hours, minutes, and seconds using successive modular division through constants like 86,400,000 and 3,600,000. If the target is in the past, the absolute value is displayed instead.
Can I count down to a specific time, not just a date?
Yes. Enter both a date and a time to get a precise countdown down to the second. If you only enter a date, it counts down to midnight at the start of that day.
Does the countdown use my local timezone?
Yes. The countdown is calculated relative to your device's local timezone, so it always shows the correct time remaining for where you are.
Can I share a countdown link with someone?
The countdown runs locally in your browser. You can bookmark the page to return to it, but the target date is stored on your device.
