QR Forever

No expiration date

Free event QR code for calendars

An event QR code carries the title, date, time, and place of your event, so people who scan it can add it to their calendar in one tap. Fill in the form, download the code, and put it on invitations or posters. It is static and does not expire.

You can also turn it into a printable 3D object: a table stand, a keychain, or a wall plaque.

Preparing your design…

3MF keeps the two colors per part. Assign the filaments in your slicer; automatic assignment depends on the program. STL does not keep colors.

Customize the design

Screen colors are approximate; assign real filaments in the slicer.

Your links, images, and data (Wi-Fi, contacts, messages, events) are processed in this browser and never sent to a server. The files you download do contain the information you encode, including Wi-Fi passwords.

Event in three steps

How to make a calendar QR code

Have the date, start and end time, and location at hand.

1

Enter the event details

Add a title, then the start and end, or tick “All day.” The place and a short description are optional; keep them brief, since everything is stored in the code.

2

Style the code

Choose colors that suit your invitation. A calendar code holds more data than a link, so print it a little larger.

3

Download and test

Download PNG or SVG. Scan it with an iPhone and an Android phone to check that the date and time arrive correctly before you print.

Good to know about event QR codes

Times have no time zone

The code stores a local date and time, with no time zone. It lands at the same clock time wherever it is scanned, which suits in-person events best.

Dates are fixed

Everything is inside the code, so there is no way to change the date afterward. If plans move, make and distribute a new code.

Short is scannable

Every extra word makes the code denser. A concise title and place give a cleaner code that reads easily from a poster.

A souvenir, too

For weddings or conferences, a 3D keychain with the event link doubles as a keepsake.

Common questions

About event QR codes

What organizers usually ask.

Which apps can read an event code?

Most phone cameras and QR readers recognize calendar events and offer to add them. Behavior varies by phone and app, so scan a sample before you print.

Does it support recurring events or reminders?

No. It creates a single event with a title, start and end (or an all-day date), a place, and a description. For repeating events, make one code per date or link to a web page instead.

Does the event QR code expire?

No. The event is stored in the code, with no server or account. It always opens, but a past date stays past, so remove old posters.

Can I link to an event page instead?

Yes. If you want guests to see a full page with maps, tickets or updates, use a link QR code. Then you can edit the page without changing the code.
