 | recurrenceRule        | A recurrence rule, commonly referred to as an RRULE, defines the repeat pattern or rule for to-dos, journal entries and events. If specified, RRULE can be used to compute the recurrence set (the complete set of recurrence instances in a calendar component). You can use a generator like this [one](https://www.textmagic.com/free-tools/rrule-generator) | `FREQ=DAILY`
 | sequence      | For sending an update for an event (with the same uid), defines the revision sequence number. | `2`
 | busyStatus    | Used to specify busy status for Microsoft applications, like Outlook. See [Microsoft spec](https://docs.microsoft.com/en-us/openspecs/exchange_server_protocols/ms-oxcical/cd68eae7-ed65-4dd3-8ea7-ad585c76c736). | `'BUSY'` OR `'FREE'` OR `'TENTATIVE`' OR `'OOF'`
+| transp        | Used to specify event transparency (does event consume actual time of an individual). Used by Google Calendar to determine if event should change attendees availability to 'Busy' or not. | `'TRANSPARENT'` OR `'OPAQUE'`
 | classification    | This property defines the access classification for a calendar component. See [iCalender spec](https://icalendar.org/iCalendar-RFC-5545/3-8-1-3-classification.html). | `'PUBLIC'` OR `'PRIVATE'` OR `'CONFIDENTIAL`' OR any non-standard string
 | created | Date-time representing event's creation date. Provide a date-time in UTC | [2000, 1, 5, 10, 0] (January 5, 2000 GMT +00:00)
 | lastModified | Date-time representing date when event was last modified. Provide a date-time in UTC | [2000, 1, 5, 10, 0] (January 5, 2000 GMT +00:00)
