iCalendar QR Code Decoder

Extract calendar events, meeting dates and times from QR codes

Our free iCalendar QR code decoder reads event data encoded as iCalendar text, including titles, dates, start and end times, and locations when provided. Calendar events use VEVENT blocks, with fields such as SUMMARY, DTSTART and DTEND. A trailing Z on a date-time means it is expressed in UTC.

Frequently asked questions

What do DTSTART, DTEND and SUMMARY mean in iCalendar data?

DTSTART specifies the event start, DTEND its end when present, and SUMMARY its title. These properties appear in a VEVENT component.

What does Z mean at the end of an iCalendar date-time?

A trailing Z marks a UTC date-time, for example 20261102T100000Z. Other times may be floating or use a TZID time-zone reference.

Why does an iCalendar event span multiple text lines?

iCalendar content lines may be folded for transport. A parser unfolds continuation lines before interpreting properties such as DESCRIPTION and LOCATION.
