Calendar Event QR Code Generator
Create calendar event QR codes that let people add your event to their calendar with a single scan—no manual entry required.
How It Works
When someone scans your event QR code, their device recognizes it as a calendar event and offers to add it to their calendar app. This works seamlessly with Google Calendar, Apple Calendar, Outlook, and most other calendar applications.
Format Overview
Event QR codes use the iCalendar format (RFC 5545), a widely-adopted standard for exchanging calendar and scheduling information. The structure looks like this:
BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//QR Toaster//Event QR//EN
BEGIN:VEVENT
SUMMARY:Team Meeting
DTSTART:20250311T140000Z
DTEND:20250311T150000Z
LOCATION:Conference Room A
DESCRIPTION:Monthly team sync meeting
END:VEVENT
END:VCALENDARKey components:
- SUMMARY: Event title/name
- DTSTART: Start date and time in ISO 8601 format (UTC timezone)
- DTEND: End date and time (optional but recommended)
- LOCATION: Where the event takes place
- DESCRIPTION: Additional details about the event
Date and Time Format
Times are stored in UTC timezone using the format YYYYMMDDTHHMMSSZ. For all-day events, the format changes to YYYYMMDD with the VALUE=DATE parameter. The generator handles these conversions automatically based on your local timezone.
Compatibility
- iOS: Works with native Calendar app via QR scanner
- Android: Compatible with Google Calendar and most calendar apps
- Desktop: Can be imported into Outlook, Apple Calendar, Google Calendar, and other desktop calendar software
- Cross-platform: iCalendar is an open standard supported by virtually all modern calendar applications
Tips for Best Results
- Include end time: While optional, specifying an end time helps attendees block the correct amount of time
- Be specific with location: Include full addresses for physical events, or meeting links for virtual events
- Keep descriptions concise: Long descriptions create larger, more complex QR codes. Include only essential information
- Test timezone handling: Verify that the event appears at the correct time when scanned in different timezones
- All-day events: Use the all-day checkbox for events that don't have specific times (conferences, holidays, etc.)
Use Cases
- Conference and workshop schedules
- Meetup and networking event invitations
- Webinar registration confirmations
- Party and social gathering invites
- Appointment reminders
- Public event flyers and posters
Size Considerations
Be mindful that longer descriptions and detailed location information increase the complexity of your QR code. If you have extensive event details, consider keeping the QR code simple and providing a URL in the description that links to a full event page.
