Second-accurate live countdown to any date you pick. Share the link, go fullscreen.
The timer ticks live every second and shows days, hours, minutes and seconds in large numerals. The browser tab title also reflects the remaining time — perfect for keeping it in the background. The fullscreen button turns the timer into a kiosk display. Settings and target date are stored in localStorage and shared via the URL — every recipient sees the exact same countdown.
Click Copy share link — the URL embeds title, date and time as parameters. Anyone opening the link sees the same countdown. Perfect for invitations, save-the-date emails, or Slack pings before a release.
