Questions

Calendar event or Google Calendar link, which should I choose?

A calendar event stores everything in the code, with no internet needed, but not every phone understands it. Some camera apps offer to add it, others only show the text. A Google Calendar link opens Google's add-event page in the browser on any phone, but guests need a Google account to save it. Test both with the phones your guests use.

How are time zones handled?

You choose the time zone the event happens in, and we store the time in universal time. Each guest's calendar then shows it in their own time, so an online event at 7 pm in London shows as 2 pm in New York.

What about all-day events?

Tick "All-day event" and choose the dates. They're stored as dates, without times, so they show on the right days in every time zone.

Can I change the event after printing?

No. The details are stored in the code. If the date or place changes, make a new code. For events that may change, a link code to an event page you control is safer.

Do you see my event?

No. Your codes are made in your browser. Nothing you type is sent anywhere.
