# exceptDate

Defines a [Date](https://schema.org.ai/Date) or [DateTime](https://schema.org.ai/DateTime) during which a scheduled [Event](https://schema.org.ai/Event) will not take place. The property allows exceptions to a [Schedule](https://schema.org.ai/Schedule) to be specified. If an exception is specified as a [DateTime](https://schema.org.ai/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.ai/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.

## 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 |
|------|-------------|
| [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. |
