How to Create a Calendar Event QR Code

A calendar event QR code takes the friction out of event promotion. Instead of asking attendees to manually create a calendar entry, you give them a code that does it in one scan. This is invaluable for conferences, workshops, meetups, weddings, and any occasion where you want people to remember the date and show up.

Steps to Generate Your QR Code

  1. Enter the event title, start date, and start time.
  2. Optionally add an end date/time, location, and description.
  3. Toggle all-day if the event does not have specific times.
  4. Download the QR code and add it to your invitations, posters, or event website.

Common Use Cases

  • Conference invitations — let attendees add sessions to their calendar from a printed schedule.
  • Wedding invitations — include a QR code so guests save the date instantly.
  • Classroom schedules — students scan to add exam dates or assignment deadlines.
  • Concert tickets — embed the show date and venue on the ticket itself.
  • Recurring meetups — print on community board flyers so new members save the next date.

About the iCalendar Format

The event QR code uses the iCalendar / vEvent format (RFC 5545). The encoded text begins with BEGIN:VEVENT and includes properties like SUMMARY (title), DTSTART (start datetime), DTEND (end datetime), LOCATION, and DESCRIPTION. This format has been the calendar interchange standard since 1998 and is universally supported.

Frequently Asked Questions

What is a calendar event QR code?
A calendar event QR code encodes event details — title, start/end date and time, location, and description — in the iCalendar (vEvent) format. When scanned, the phone offers to add the event directly to the user's calendar app.
Which calendar apps are supported?
The iCalendar format is supported by virtually all calendar apps: Apple Calendar, Google Calendar, Microsoft Outlook, Samsung Calendar, and others. When scanned, the device's default calendar app opens with all event details pre-filled.
Can I create all-day events?
Yes. Toggle the all-day option and the generated code will encode a date-only event without specific start and end times. This is useful for holidays, deadlines, and multi-day conferences.
Is there a limit on the description length?
While the QR standard supports thousands of characters, keeping your total event data under 500 characters produces the most scannable code. For detailed agendas, consider linking to a webpage in the description field.
Does this set reminders automatically?
Reminders depend on the user's calendar app settings. The QR code encodes the event itself, and the calendar app applies the user's default reminder rules.
