Who this is for: For anyone counting down to a moment on the calendar — a wedding day, a product launch, an exam, a flight, a deadline — who wants the number in front of them instead of doing calendar math.
Not the right tool for: Duration timing (like 10 minutes) — set a duration on the countdown timer instead · Notifications after you close the page — the countdown lives in the page, exact when reopened
Count down to any date and time — days, hours, minutes, and seconds, live. Weddings, launches, exams, trips, deadlines: pick the moment and watch it approach.
Quick answer: A date countdown shows the exact time remaining to a calendar date — days, hours, minutes, and seconds, updating live. Pick your target above; it is interpreted in your local timezone and stops at zero with a completion message.

How does the date countdown work?
Pick a target date and time; the page computes the gap to your device's clock every quarter second and splits it into days, hours, minutes, and seconds. The target is interpreted in your own timezone, so a countdown to midnight means your midnight. When the moment passes, the countdown switches to a completion message instead of rolling into negative numbers. Long ranges are handled honestly: 500 days shows as 500 days plus hours, not a wall of seconds.
Common uses

Frequently Asked Questions
How many days until my date?
Set the date above and the days-remaining figure updates live — along with hours, minutes, and seconds. The calculation uses your device clock, so it is exact for your timezone.
Which timezone does the countdown use?
Your device's local timezone. A target of midnight means midnight where you are. If you are coordinating across timezones, compute the target in the timezone of the event.
Can I put this countdown on my website?
Yes — the website countdown generator builds an embeddable version of the same countdown with an iframe or script snippet you can paste into any site or store.
What happens when the date passes?
The countdown stops at zero and shows a completion message you can customize in the generator (the default is "It's time!").
Does it keep counting if I close the page?
The countdown lives in the page, but it is always exact when reopened: it recomputes from your device clock, never from how long the page was open.
