How do I share a countdown?

Click "Copy shareable link" — the URL encodes the target date, time zone, and title, so anyone opening it sees the same live countdown.

Can I embed the countdown on my website?

Yes. Copy the iframe code snippet from the "Embed this countdown" section and paste it into any webpage.

What happens when the target date passes?

The display switches to "Since" mode and counts up from the target moment, showing how long ago it occurred.

What time zone should I use?

Use the time zone where the event occurs. The countdown stores the absolute moment, so it ticks correctly for all viewers regardless of their local time zone.
