Calendar Event QR Code Generator
QR that adds an event to any calendar with one scan. iCal/VEVENT format.
How does a calendar QR code work?
A calendar QR encodes the event in the iCal VEVENT format — when scanned, the recipient's phone offers to add the event to their default calendar app (iOS Calendar, Google Calendar, Outlook). Encoding the date in the right format is the most common pitfall: VEVENT requires UTC timestamps in YYYYMMDDTHHMMSSZ form, with no separators. Get this wrong and the event silently fails to import. This generator handles the formatting for you, computed locally on your device.
