What happens when someone scans a calendar QR code?

Their phone reads a standard iCalendar event and offers to save it. On iPhone it opens in Apple Calendar; on Android it opens in Google Calendar or whichever calendar app is set as default.

Do I need to pick a time zone?

Times are stored in universal time (UTC), converted from the time you type, so the event lands at the right moment wherever it is scanned. All-day events are date-only and have no time zone at all.

Can I add a reminder to the event?

Yes — pick anything from 5 minutes to a day before, and the saved event carries a built-in alert. The person scanning can still change it in their calendar app afterwards.

If I edit the event later, does the code update?

No. A static code contains the event itself, so reprints are needed for changes. The upside: it never expires and needs no server — the whole event lives inside the squares.

Is this free for invitations and posters?

Completely — free forever, no signup, no watermark, any resolution. Print it on wedding invites, gig posters, or meetup flyers as much as you like.
