What Countdown does
Live countdown to any future date — copy the link to share.
How it works
Intl.DateTimeFormat for locale, Temporal API where available, and a battle-tested cron parser. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
