Why a calendar QR code
A date printed on a poster is easy to forget by the time the evening comes. A calendar QR code carries the event itself — its name, start and end time and a description — in the standard iCalendar format, so a scan offers to add it to the phone's calendar with nothing retyped. The details sit inside the image, which means the code works without our servers but cannot be edited; a changed date needs a new code.
- Scanning offers Add to calendar with the title, times and notes already filled in.
- Times are saved as an exact moment, so guests in other time zones see the correct local hour.
- No internet is needed to read the event, because nothing is fetched from a server.
- Once saved, the entry behaves like any other appointment, with the calendar's usual alerts.
Webinars and online talks
A code on the announcement saves the start time, with the joining link pasted into the description.
School and kindergarten notices
Parent evenings, closures and trips go into family calendars instead of staying on a sheet in the school bag.
Medical and service appointments
A card handed over at the desk puts the next visit, with preparation notes, into the patient's phone.
Shop openings and sales
Window posters and flyers announce an opening day that customers save before walking on.
Club fixtures
Each match on the season poster gets its own code, so supporters save only the games they plan to attend.

A calendar QR code turns a printed date into a one-tap calendar entry. Scan it, and the event — with its times and description — is ready to add to the recipient's own calendar.
What is this QR code?
A calendar QR code encodes an iCalendar event with a title, a start and end time and a description, which scanning offers to add directly to a calendar app.
Best use cases
- ✓A concert flyer with an 'Add to Calendar' button showing the exact date and time.
- ✓A wedding invitation that adds the event straight to a guest's calendar.
- ✓The first session of a course, with the joining details in the notes.
- ✓An event ticket with a date easy to check against a personal schedule.
How to generate your QR code
Type the event name as guests should see it in their calendar.
Pick the start date and time, and an end time if the event has a fixed length.
Use the description for the address, dress code or joining link.
Scan the code with an iPhone and an Android phone and open the saved entry on each.
Frequently Asked Questions
Which calendar apps support this?
The iCalendar (.ics) format is supported by all major calendar apps, including Google Calendar, Apple Calendar, and Outlook.
How is calendar different from a reminder QR code?
A calendar event has a start time and, optionally, an end time, and it is saved into the phone's calendar, while a reminder is a single point-in-time notification without a duration.
Which phones offer to add the event?
The iPhone Camera app recognises calendar codes and shows an Add to Calendar option. On Android, Google Lens and most scanner apps offer the same; a few basic camera apps only display the raw text.
Can I add a venue address?
The form has no separate location field. Put the address, a map link or a room number in the description, which calendar apps show together with the event.
How are time zones handled?
You enter the time as it is in your own time zone, and the code stores it as an exact moment. Each phone then shows it in its local time, which is right for online events and harmless for in-person ones.
Can the code hold a recurring event?
No. One code holds one event with a start and an optional end. For a weekly class, create a code per session or link a shared calendar with a URL code.
What if I leave out the end time?
The event is saved with identical start and end, as a single point in time. Add an end time if guests should see how long it lasts.
Can I change the date after printing?
No. The event is stored in the image itself, so there is nothing on a server to update and no scan count. If the date might move, print an Event code instead, which stays editable.
