Event QR Code Generator

Q: What time zone does the event use?

None — deliberately. The times are encoded as floating local time, meaning 7pm stays 7pm regardless of what the scanning phone is set to. For a physical event that is what you want: a poster for a 7pm gig should put 7pm in the calendar of a visitor whose phone is still on another country's time zone, not 2am.

Q: Does scanning it send me an invitation or RSVP?

No. Nothing is transmitted anywhere. The code contains the event details as text, and the phone creates a local calendar entry from them — you receive no notification, no RSVP and no attendee list. If you need to know who is coming, pair the code with a sign-up form.

Q: Can I encode a recurring event?

The iCalendar format supports recurrence rules, but this tool encodes single events on purpose. Recurrence rules are handled inconsistently across phone calendar apps, and a rule that silently imports wrong is worse than a single correct entry. For a weekly class, a code for the next session is more reliable than one claiming to repeat forever.

Q: Why does my event code look so much busier than a link code?

Because it carries the whole event rather than an address. A VEVENT with a name, location, two timestamps and a description easily runs past 200 characters, where a short link is 25. Trimming the description is the fastest way to simplify the code — the analysis panel shows the character count so you can see the effect as you edit.

What It Does

This tool encodes your event as an iCalendar VEVENT — the same format calendar invitations use — so scanning it opens an 'Add to calendar' screen with the name, time and location already filled in. Nothing is hosted anywhere and no invitation is sent; the event details live inside the code itself, which means it keeps working with no internet connection at all.

When to Use It

You are printing posters or flyers for a gig, class or meetup and want the date to land in people's calendars rather than their intentions.
You run a conference and want a code per session on the programme so attendees can build their own schedule.
You are sending physical invitations and want the details captured without anyone typing them.
You run a recurring class and want a code on the noticeboard for the next session.

Worked Examples

Evening gig with a set end time

Both times set explicitly. The analysis confirms the hours are encoded as local floating time, so 7:30pm stays 7:30pm for a visitor whose phone is still on another country's clock.

No end time

Calendars will invent a default duration, usually an hour. The analysis flags it, because a guessed end time looks careless in someone's day view.

A long description making a dense code

Watch the character count climb in the analysis. Everything here is baked into the code itself, so a paragraph of detail is paid for in module size — put it on a web page instead.

Common Mistakes

Leaving the end time blank. Calendars fall back to a default duration, usually an hour, which is often wrong and looks careless in someone's day view. Set it explicitly.
Writing a long description. Every character is encoded into the code, and a paragraph of detail makes a visibly denser symbol that scans worse from a poster. Put the detail on a web page and keep the calendar entry to the essentials.
Expecting the event to update. This is a static code with the details baked in — if the time changes, everyone who already scanned it keeps the old entry, and every printed copy is wrong. For events likely to move, link to a page instead.
Assuming every scanner handles a bare VEVENT. iOS reads it reliably and most Android scanners do, but a few want the full VCALENDAR wrapper. Test on both platforms before a large print run.

How to Use

1. Enter the event name and location. 2. Set the start and end times using the pickers — these are treated as local time at the event. 3. Keep any description short, since it makes the code denser. 4. Check the analysis, download, and test on both an iPhone and an Android phone before printing.
