How it works

How to make a Calendar event QR code

  1. 1

    Enter the event details

    Add a title, start time, end time, location and up to 300 characters of details. Only the title and start time are required.

  2. 2

    Check the date and times

    These are the details people rely on most. Read them back twice, including am and pm.

  3. 3

    Style and test

    Scan the preview and add the event to your own calendar to check every field.

  4. 4

    Download

    Save it as PNG, JPEG, SVG or PDF, from 512 to 4096 px.

Where it helps

Use cases.

  • Invitations

    Add a code to printed invites so guests save the date the moment they open the envelope.

  • Conferences and talks

    Put a code on each session poster so attendees can add it to their own schedule.

  • Appointments and courses

    Give clients a card with a code for their next appointment or the first class of a course.

  • Community notices

    Pin a code to the noticeboard for the next meeting, fair or open day.

Before you print

Tips that save a reprint.

  • Test on an iPhone and an Android phone. The iPhone camera adds events directly, while some Android cameras need Google Lens to read calendar codes.
  • Times are saved without a time zone, so the event shows the same clock time wherever the phone is. For online events with an international audience, write the time zone in the details.
  • Keep the details short. A long description makes a dense code, so link to a full page with a separate URL code if you need more.
  • Print the date and time in text beside the code, for anyone who can't scan it.
  • Print at least 2.5 cm (1 in) wide, because event codes hold more data than a simple link.

Their phone reads the event and offers to add it to their calendar, with the title, times, location and details filled in.

Support varies. Many Android phones read calendar codes through Google Lens, while some built-in camera apps only show the raw text. The iPhone Camera app handles them directly.

It uses the iCalendar VEVENT format, the standard that calendar apps understand.

No. The details are stored in the code, so a new time means a new code. If plans might change, a dynamic code pointing to an event page you can edit is the safer choice.

No. The phone can read the event and save it to the calendar without a connection.

Need to change it after printing?

A dynamic code can point somewhere new any time, shows you who scans it, and keeps working even if you cancel.
