## Expected Types

| Type | Description |
|------|-------------|
| [Date](https://schema.org.ai/Date) | A date value in [ISO 8601 date format](http://en.wikipedia.org/wiki/ISO_8601). |
| [DateTime](https://schema.org.ai/DateTime) | A combination of date and time of day in the form \[-\]CCYY-MM-DDThh:mm:ss\[Z\|(+\|-)hh:mm\] (see Chapter 5.4 of ISO 8601). |

## Used on Types

| Type | Description |
|------|-------------|
| [CreativeWorkSeason](https://schema.org.ai/CreativeWorkSeason) | A media season, e.g. TV, radio, video game etc. |
| [CreativeWorkSeries](https://schema.org.ai/CreativeWorkSeries) | A CreativeWorkSeries in schema.org is a group of related items, typically but not necessarily of the same kind. CreativeWorkSeries are usually organized into some order, often chronological. Unlike [ItemList](https://schema.org.ai/ItemList) which is a general purpose data structure for lists of things, the emphasis with CreativeWorkSeries is on published materials (written e.g. books and periodicals, or media such as TV, radio and games). Specific subtypes are available for describing [TVSeries](https://schema.org.ai/TVSeries), [RadioSeries](https://schema.org.ai/RadioSeries), [MovieSeries](https://schema.org.ai/MovieSeries), [BookSeries](https://schema.org.ai/BookSeries), [Periodical](https://schema.org.ai/Periodical) and [VideoGameSeries](https://schema.org.ai/VideoGameSeries). In each case, the [hasPart](https://schema.org.ai/hasPart) / [isPartOf](https://schema.org.ai/isPartOf) properties can be used to relate the CreativeWorkSeries to its parts. The general CreativeWorkSeries type serves largely just to organize these more specific and practical subtypes. It is common for properties applicable to an item from the series to be usefully applied to the containing group. Schema.org attempts to anticipate some of these cases, but publishers should be free to apply properties of the series parts to the series as a whole wherever they seem appropriate. |
| [DatedMoneySpecification](https://schema.org.ai/DatedMoneySpecification) | A DatedMoneySpecification represents monetary values with optional start and end dates. For example, this could represent an employee's salary over a specific period of time. \_\_Note:\_\_ This type has been superseded by [MonetaryAmount](https://schema.org.ai/MonetaryAmount), use of that type is recommended. |
| [EducationalOccupationalProgram](https://schema.org.ai/EducationalOccupationalProgram) | A program offered by an institution which determines the learning progress to achieve an outcome, usually a credential like a degree or certificate. This would define a discrete set of opportunities (e.g., job, courses) that together constitute a program with a clear start, end, set of requirements, and transition to a new occupational opportunity (e.g., a job), or sometimes a higher educational opportunity (e.g., an advanced degree). |
| [Event](https://schema.org.ai/Event) | An event happening at a certain time and location, such as a concert, lecture, or festival. Ticketing information may be added via the [offers](https://schema.org.ai/offers) property. Repeated events may be structured as separate Event objects. |
| [MerchantReturnPolicySeasonalOverride](https://schema.org.ai/MerchantReturnPolicySeasonalOverride) | A seasonal override of a return policy, for example used for holidays. |
| [Role](https://schema.org.ai/Role) | Represents additional information about a relationship or property. For example a Role can be used to say that a 'member' role linking some SportsTeam to a player occurred during a particular time period. Or that a Person's 'actor' role in a Movie was for some particular characterName. Such properties can be attached to a Role entity, which is then associated with the main entities using ordinary properties like 'member' or 'actor'. See also [blog post](https://blog.schema.org/2014/06/16/introducing-role/). |
| [Schedule](https://schema.org.ai/Schedule) | A schedule defines a repeating time period used to describe a regularly occurring [Event](https://schema.org.ai/Event). At a minimum a schedule will specify [repeatFrequency](https://schema.org.ai/repeatFrequency) which describes the interval between occurrences of the event. Additional information can be provided to specify the schedule more precisely. This includes identifying the day(s) of the week or month when the recurring event will take place, in addition to its start and end time. Schedules may also have start and end dates to indicate when they are active, e.g. to define a limited calendar of events. |
