Event QR code: add to calendar with one scan

An event QR code holds a standard iCalendar entry (VEVENT) with the title, start and end time (or all-day dates), location and description. When someone scans it, the phone recognizes an event and offers to add it to their calendar. No typing, and no forgotten dates.

Use it on wedding and party invitations, save-the-dates, event posters, tickets and wristbands, school newsletters, company events and webinars (put the join link in the description).

Everything happens in your browser; your event details aren't uploaded.

The time is stored in UTC, which sounds odd but is exactly what makes it work everywhere:

• You enter 7:00 PM in your local time.
• The generator converts it to UTC (for New York in winter, that's midnight UTC).
• Each phone converts it back to its own time zone: 7:00 PM in New York, 4:00 PM in Los Angeles.

That's ideal for virtual events with attendees across the country. Daylight saving time is applied based on the date you pick.

All-day events (a festival, a day off) have dates only, so time zones don't matter; they appear in the all-day row. For multi-day events, enter the last day as the end date and the generator writes it the way the calendar standard expects.

Field	Tip
Title	Specific: "Emily & Jake's Wedding," not just "Wedding"
Start	The time guests should arrive, if that differs from the program start
End	Optional, but it shows how long people are busy
Location	Full address with city, so the calendar can open a map
Description	Dress code, parking, tickets or an online link, briefly

Keep it short. Every character makes the code denser, and dense codes are hard to scan on a printed invitation. Put the details on a web page and add its link to the description.

The code holds a single event, with no recurrence or custom reminders; the phone's calendar uses its own alert settings.

Option	What guests get	Best for
Event QR code	A calendar entry with all the details	One-time events with short info
Location QR code	A map with directions	Venues that are hard to find
URL QR code to an event page	A website with RSVP and schedule	Lots of info, or details that may change

Many invitations use two codes: "Save the date" (event) and "Directions" (location). Label them clearly and give them different colors.

Most current iPhone and Android phones recognize calendar QR codes. If an older phone only shows text, the details are still readable, but print the date and venue on the invitation too.

Design it in the main QR code generator studio: templates, colors, a calendar icon or your monogram, and a frame label such as "Save the date."

• Size: 1–1.25 in (2.5–3 cm) works on a hand-held card if the description is short.
• Color: match your stationery, but keep the code dark on a light background. Gold or pastel codes on white are often too faint; the readability check warns under 4.5:1 contrast.
• Format: PDF or SVG for the printer, PNG for digital invitations.
• Test with an iPhone and an Android phone, and confirm the entry lands on the right day and hour. Printed codes can't be edited, so finalize the details first.
