Calendar event generator

How to make a Calendar event

Three steps:

1. Open the generator and pick Calendar event.
2. Fill in the fields — the preview updates as you type.
3. Download PNG for screens, or SVG for anything going to print.

Example

Scanners recognise this content by its prefix, so the text has to be formatted exactly. The generator handles the escaping — a Wi-Fi password containing a semicolon, for instance, breaks a hand-written payload.

BEGIN:VEVENT
SUMMARY:Launch party
DTSTART:20260305T183000
DTEND:20260305T213000
LOCATION:The Depot
END:VEVENT

Practical tips

• Test the printed code with a phone before you order a thousand of them. Print, lighting and surface all affect scanning.
• Leave the quiet zone alone. Cropping the blank border is the most common reason a code stops scanning.
• Dark code on a light background. Inverted codes work on some scanners and fail on many.
