CALENDAR EVENT

QR code for a calendar event

An iCal event in the code itself — title, time and place — so it can be added without a network connection.

An event QR code stores a calendar entry — title, time, place — that a phone offers to add to its calendar.

Style this code
Style this code — colour, shape, branding, frame and output
Colour & contrastThe ink, the paper behind it, and the three eyes. Every choice is contrast-checked as you make it.
Foreground
18.0:1 against the background — clears the 4.5:1 a camera wants margin on.
Background
Eye colours
ShapeHow the squares are drawn. The three eyes are styled apart from the data, because a scanner finds the code by them.
Modules
Every shape here is decode-tested before it is offered. Shapes that lose the symbol — diamond, star, heart — are not on this list, however good they look.
Eye frame
Eye centre
BrandingYour mark on the code. Every picture here costs scanability — the notes say how much, and the preview is the truth.
Logo image
PNG, JPEG or WebP, up to 2MB. The modules beneath it are cleared and error correction rises to cover the hole.
Background picture
Sits behind the modules, quiet zone included. A busy picture is the classic reason a decorated code stops scanning — check the preview with a phone before printing.
Foreground texture
Washes over the ink itself, so it is capped well below full strength — at full strength there is no code left to scan.
Frame & captionA border and a line of text around the code — the "scan me" that tells a passer-by what it is for.
Frame style
A frame is drawn outside the quiet zone, never into it — the canvas grows instead, so the border cannot cost the code its margin.
OutputWhat comes out of the download buttons, and what the symbol actually carries.
Options
Automatic picks the smallest encoding that carries your text, and is right almost always. The other three exist for older scanners that expect one specific encoding; each refuses text it cannot carry rather than mangling it. Encodings we cannot convert to correctly are not offered at all.The margin never goes below 4 — ISO/IEC 18004's minimum; smaller is not a QR code. A logo raises error correction to at least Q. Encoding is chosen by the encoder per symbol and shown in the readout — a manual charset menu only makes codes bigger.

A press file at the finished size: 3mm bleed, crop marks and a trim box a print shop’s checks read. The code is drawn black on white whatever the design above — how a colour prints is something only a test print can show.

No account · no watermark · no scan limits

The event is inside the code

The whole VEVENT is encoded, so nothing is fetched when someone scans it. That is the reason to use this rather than a link to a calendar page: it works in a venue with no signal, which is where people scan event codes.

Do phone cameras open event QR codes?

Some phone cameras offer "Add to calendar" straight from the scan and some show the raw text. It is not a defect in the code — the payload is standard iCal — but it does mean a printed instruction beside the code earns its space.

Times are written with their zone

The times you enter are local wall time and the code carries the timezone with them, so a scan in another zone lands at the right moment rather than three hours out.

Event QR codes

Why is the code larger than my other ones?

An event carries more characters than a URL, so the symbol needs a higher version. Print it larger, or link to a page if the poster is small.

Can I change the event after printing?

Not with this one — the details are in the ink. If the time might move, encode a short link to a page you can edit instead.

Does it handle recurring events?

This form makes a single event. A repeating series is better served by a subscription link than by a printed code.

What happens if someone scans it in another timezone?

The code carries the event’s timezone alongside its times, so a phone set elsewhere shows the correct local moment rather than the raw clock reading.
