Defines the day(s) of the week on which a recurring [Event](https://schema.org/Event) takes place. May be specified using either [DayOfWeek](https://schema.org/DayOfWeek), or alternatively [Text](https://schema.org/Text) conforming to iCal's syntax for byDay recurrence rules.
Defines the month(s) of the year on which a recurring [Event](https://schema.org/Event) takes place. Specified as an [Integer](https://schema.org/Integer) between 1-12. January is 1.
Defines the day(s) of the month on which a recurring [Event](https://schema.org/Event) takes place. Specified as an [Integer](https://schema.org/Integer) between 1-31.
Defines the week(s) of the month on which a recurring Event takes place. Specified as an Integer between 1-5. For clarity, byMonthWeek is best used in conjunction with byDay to indicate concepts like the first and third Mondays of a month.
The duration of the item (movie, audio recording, event, etc.) in [ISO 8601 duration format](http://en.wikipedia.org/wiki/ISO_8601).
The end date and time of the item (in [ISO 8601 date format](http://en.wikipedia.org/wiki/ISO_8601)).
The endTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to end. For actions that span a period of time, when the action was performed. E.g. John wrote a book from January to *December*. For media, including audio and video, it's the time offset of the end of a clip within a larger file.
Note that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.
Associates an [Event](https://schema.org/Event) with a [Schedule](https://schema.org/Schedule). There are circumstances where it is preferable to share a schedule for a series of repeating events rather than data on the individual events themselves. For example, a website or application might prefer to publish a schedule for a weekly gym class rather than provide data on every event. A schedule could be processed by applications to add forthcoming events to a calendar. An [Event](https://schema.org/Event) that is associated with a [Schedule](https://schema.org/Schedule) using this property should not have [startDate](https://schema.org/startDate) or [endDate](https://schema.org/endDate) properties. These are instead defined within the associated [Schedule](https://schema.org/Schedule), this avoids any ambiguity for clients using the data. The property might have repeated values to specify different schedules, e.g. for different months or seasons.
Defines a [Date](https://schema.org/Date) or [DateTime](https://schema.org/DateTime) during which a scheduled [Event](https://schema.org/Event) will not take place. The property allows exceptions to a [Schedule](https://schema.org/Schedule) to be specified. If an exception is specified as a [DateTime](https://schema.org/DateTime) then only the event that would have started at that specific date and time should be excluded from the schedule. If an exception is specified as a [Date](https://schema.org/Date) then any event that is scheduled for that 24 hour period should be excluded from the schedule. This allows a whole day to be excluded from the schedule without having to itemise every scheduled event.
Defines the number of times a recurring [Event](https://schema.org/Event) will take place.
Defines the frequency at which [Event](https://schema.org/Event)s will occur according to a schedule [Schedule](https://schema.org/Schedule). The intervals between events should be defined as a [Duration](https://schema.org/Duration) of time.
Indicates the timezone for which the time(s) indicated in the [Schedule](https://schema.org/Schedule) are given. The value provided should be among those listed in the IANA Time Zone Database.
The start date and time of the item (in [ISO 8601 date format](http://en.wikipedia.org/wiki/ISO_8601)).
The startTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to start. For actions that span a period of time, when the action was performed. E.g. John wrote a book from *January* to December. For media, including audio and video, it's the time offset of the start of a clip within a larger file.
Note that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.
