Event (Add-to-Calendar) QR Code

Scan and add straight to the calendar app — no manually typing the date, time and location off an invite or poster.

Build an event code using the Text tab

How to make one with QRGenPro

Calendar events use the iCalendar (.ics) format, which — like vCard — is plain text. Paste a block like this into the Text tab, filling in your event's details in UTC (YYYYMMDDTHHMMSSZ):

BEGIN:VEVENT
SUMMARY:Product Launch Party
DTSTART:20261015T180000Z
DTEND:20261015T210000Z
LOCATION:123 Main St, Springfield
DESCRIPTION:Doors open at 6pm.
END:VEVENT

Compatibility note

Support for scanning raw VEVENT blocks directly into "add to calendar" varies by phone and camera app — some open a text preview rather than a calendar prompt. For guaranteed one-tap adding, host a full .ics file online and generate a URL QR code that links to it instead.

Frequently asked questions

Will scanning always prompt "Add to calendar"?

Not on every device — behavior depends on the scanning app. Hosting a linked .ics file and using a URL QR code is the more reliable option.

What date format does DTSTART need?

UTC format: YYYYMMDDTHHMMSSZ, e.g. 20261015T180000Z for October 15, 2026, 18:00 UTC.
