What is a Calendar QR Code?
A calendar QR code encodes a Google Calendar template link (or iCal VEVENT data). Scanning offers to add the event — title, start/end, location — to the phone's calendar. Meeting-room door cards, event posters and course notices all benefit.
Encoding structure
- Google Calendar format:
https://calendar.google.com/calendar/render?action=TEMPLATE&text=Title&dates=start/end&details=notes; - Times must be UTC (no timezone suffix) — CodeBox converts from your local time automatically;
- Location and details are optional parameters;
- iOS Calendar understands the same link.
How to generate a calendar QR code
- Fill in the title, location and start/end times;
- Confirm the dates parameter (correct UTC conversion) in the preview;
- Test-scan on a real phone to confirm the add-event popup;
- Download PNG/SVG.
Typical uses
- Meeting rooms: scan to join the schedule;
- Course timetables and training notices;
- Conference agenda quick-add.
