Event / calendar QR code generator

Generate a QR code containing a calendar event.

Input and settings

How to use it

Create a calendar-event QR from start/end date and time plus optional title, location and description. It is useful for adding a “save this event” path to invitations, posters or handouts.

Enter the start and end date/time, then add title, location and description as needed.
Make sure the end is later than the start and run the generator.
Scan the QR on target devices and confirm the event details before publishing the PNG.

Date/time input: interpreted from the creator device’s local time
End time: must be later than start
Output: 720 px PNG
Compatibility: varies by QR reader and calendar app

Turn a seminar time and venue into an add-to-calendar QR

Enter a two-hour seminar and its venue, generate the QR, then scan it on the phones your audience is likely to use and verify the displayed start/end times.

The receiving calendar app controls the import experience, so not every device presents the same screen. Time-zone-sensitive events deserve testing on more than one device or account.

A valid time range avoids ambiguous calendar entries

The generator rejects a missing or reversed start/end range. It is intended for timed events rather than a dedicated all-day-event workflow.

Use a human-readable location

A venue name plus room or entrance detail remains useful even when the calendar app does not turn the location into a map link.

Keep the description concise

A registration link, short instruction or contact detail is useful. Very long text increases QR density and can make scanning harder at small print sizes.

Verify time zones on the receiving side

The entered local date/time is converted into calendar data. For international audiences, scan the result where different time zones are actually in use.

Print event details alongside the QR

A QR should be a convenience, not the only way to know when and where the event happens.
