Webinar Countdown — Show Attendees Exactly When You Start

Drop this link in your registration confirmation or waiting-room slide. Every attendee who opens it — on any device, in any timezone — sees a countdown to the exact same start moment, because the deadline travels inside the link itself.

Common questions

Does this handle attendees in different timezones correctly?

Yes — the link encodes one exact instant, not a wall-clock time, so every attendee's device converts it to their own local time automatically and everyone counts down to the same real moment.

Can I put this in an email before the webinar starts?

Yes — that's a common use: paste the link into your registration confirmation or reminder email so attendees can see exactly how long until you go live.

What should attendees see after the countdown ends?

The board shows the countdown has reached zero; from there, switch attendees to your actual webinar link/room, since this page is the countdown itself, not the meeting.
