Câu hỏi thường gặp
Which time zone does the countdown use?
Your device's local time zone. Someone opening a shared link in another time zone sees the countdown to the same wall-clock time in their zone.
What happens when the date passes?
The timer switches to showing how long ago the event was.
Does the countdown keep running if I close the page?
The page doesn't need to stay open. Reopen it or the shared link at any time to see the current remaining time.
