# endDate

The ending time and date for this workout session.

```
var endDate: Date? { get }
```

## Discussion

This property is set to `nil` when the workout session is initialized. The system assigns an end date when the session’s state changes to [`HKWorkoutSessionState.ended`](/documentation/HealthKit/HKWorkoutSessionState/ended).
