À propos de Countdown Timer

Whether you're counting down to a vacation, a product launch, a deadline, or a birthday — our countdown timer shows the exact time remaining in days, hours, minutes, and seconds, updates in real-time, and lets you share the countdown link with others. It also handles past events to show elapsed time.

Comment l'utiliser

  1. Enter the target date and time (and timezone for international events).
  2. See the live countdown in days, hours, minutes, and seconds.
  3. Add a title and customize the display for sharing.
  4. Copy the shareable link — anyone opening it sees the same countdown in their local timezone.

Formule et méthodologie

Remaining time = target datetime − current datetime (in milliseconds). Days = floor(ms / 86400000). Hours = floor((ms % 86400000) / 3600000). Minutes = floor((ms % 3600000) / 60000). Seconds = floor((ms % 60000) / 1000). Updates every 1000ms via setInterval(). Timezone: convert both to UTC for subtraction.

Cas d'usage courants

  • Product launches and public announcements ("launching in X days")
  • Event marketing: countdown to conference, sale, or limited-time offer
  • Personal: vacation countdown, birthday or anniversary
  • Project management: days until deadline, sprint end, or release date
  • Sports: countdown to game day or season opener

Questions fréquentes

The safest approach is to store both the target time as UTC and the intended local timezone, then display the countdown relative to UTC. If the countdown crosses a DST transition, the UTC offset of the timezone changes, but the UTC target remains fixed — so the local time display adjusts accordingly. Our tool handles DST automatically using the IANA timezone database.
The display switches from countdown to "Event started!" and can optionally switch to counting up (elapsed time since the event). For recurring events (e.g., "next New Year"), you can set it to auto-reset to the next occurrence. For sales or offers with a hard deadline, the tool can show a "closed" state after zero to prevent late submissions.
