How to Make a Calendar / Event QR Code

A calendar QR code lets people add your event to their phone with a single scan — the right date, time, and place drop straight into their calendar, no typing and no "wait, was that the 15th or the 16th?" Here's how to make one for free.

Why use a QR code for an event?

The hardest part of promotion isn't getting someone interested — it's getting the details into their calendar before they forget. Every extra step loses people. A calendar QR code collapses it to one scan: the event appears in their calendar app, ready to save, with the date, time, location, and any notes already filled in.

It's perfect for posters, invitations, tickets, flyers, email signatures, and slides — anywhere you're telling people "be here, then."

How to make a calendar QR code

1. Open the QRcritter generator and click the Event tab.
2. Enter the event name.
3. Set the start (and, if you like, the end) date and time.
4. Add a location and any details — both optional but helpful.
5. Customize the colors or logo if you want it to match your invite.
6. Download the PNG for digital invites, or the SVG for printed posters and tickets.

Tips

• Label the code — "Scan to add to your calendar" tells people what it does.
• Include the location so attendees have directions in the same entry.
• Keep contrast high and size the code for the print.
• Use SVG for large posters so it stays sharp.
• Test on iPhone and Android before printing a run.
