3.6.2. To-Do Component
Provide a grouping of calendar properties that describe a to-do.
Format Definition: A "VTODO" calendar component is defined by the following notation:
todoprop = *( ; ; The following are REQUIRED, ; but MUST NOT occur more than once. ; dtstamp / uid / ; ; The following are OPTIONAL, ; but MUST NOT occur more than once. ; class / completed / created / description / dtstart / geo / last-mod / location / organizer / percent / priority / recurid / seq / status / summary / url / ; ; The following is OPTIONAL, ; but SHOULD NOT occur more than once. ; rrule / ; ; Either 'due' or 'duration' MAY appear in ; a 'todoprop', but 'due' and 'duration' ; MUST NOT occur in the same 'todoprop'. ; If 'duration' appear in a 'todoprop', ; then 'dtstart' MUST also appear in ; the same 'todoprop'. ; due / duration / ; ; The following are OPTIONAL, ; and MAY occur more than once. ; attach / attendee / categories / comment / contact / exdate / rstatus / related / resources / rdate / x-prop / iana-prop ; )
A "VTODO" calendar component is a grouping of component properties and possibly "VALARM" calendar components that represent an action-item or assignment. For example, it can be used to represent an item of work assigned to an individual; such as "turn in travel expense today".
The "VTODO" calendar component cannot be nested within another calendar component. However, "VTODO" calendar components can be related to each other or to a "VEVENT" or to a "VJOURNAL" calendar component with the "RELATED-TO" property.
The following is an example of a "VTODO" calendar component that needs to be completed before May 1st, 2007. On midnight May 1st, 2007 this to-do would be considered overdue.
BEGIN:VTODO UID:20070313T123432Zemail@example.com DTSTAMP:20070313T123432Z DUE;VALUE=DATE:20070501 SUMMARY:Submit Quebec Income Tax Return for 2006 CLASS:CONFIDENTIAL CATEGORIES:FAMILY,FINANCE STATUS:NEEDS-ACTION END:VTODO

Need to test your iCalendar feeds? The iCalendar Validator provides developers and testers a method to validate their iCalendar feeds, which can take data from either a URL, file or text snippet and compare it against the RFC 5545 specification. We believe we have one of the best iCalendar validation tools available on the internet. More information about the validator can be found here.
