How an event QR code works
An event QR code carries a standard iCalendar event — the same format calendar invitations use — with the title, start and end time, location, and description inside the image. Scanning it offers to add the event to the phone's calendar in a couple of taps. No typing dates on a poster, no "I'll add it later" that never happens.
Put one on wedding invitations, conference badges and session signage, concert and league posters, open-house flyers, school newsletters — anywhere the difference between "saw it" and "calendared it" matters.
Filling in the fields
Title and start time are required; end time, location, and description are optional. The all-day checkbox switches the event to a date (or date range) without times — right for festivals, deadlines, and holidays. Keep the description brief: it's the field that bloats the code fastest, and the scanability tag under the preview will tell you when it's getting dense.
One timezone caveat
The times you enter are encoded as local "wall-clock" times, and each phone interprets them in its own timezone. For a physical event that's exactly what you want — 7 PM on the poster means 7 PM at the venue. For a virtual event with attendees across timezones, state the timezone in the title or description ("Webinar — 3 PM Eastern") so nobody guesses. And like every printed QR code it's static: if the event moves, reprint.
Frequently asked questions
Which calendar apps does it work with?
Any app registered to handle calendar events — Apple Calendar on iOS and Google Calendar on Android cover nearly everyone. The payload is standard iCalendar, the same format email invitations use.
How are timezones handled?
Times are encoded as local wall-clock times and each phone reads them in its own timezone. Perfect for in-person events; for virtual events with a spread-out audience, name the timezone in the title or description.
Can I make an all-day event?
Yes — tick the all-day checkbox and the event is encoded as a date (or date range) without times, which calendars display as an all-day banner.
Can I update the event after printing?
No — the details live inside the image, so a printed code is fixed. If details might change, encode a URL to an event page you control instead, and update the page.
Is my event information uploaded anywhere?
No. The code is generated entirely in your browser; the event details are never uploaded and are only stored if you sign in and explicitly save the code.
