# isEqual(to:)

Returns a Boolean value that indicates whether a given object is a date that is exactly equal the receiver.

```
func isEqual(to otherDate: Date) -> Bool
```

## Parameters

`otherDate`

The date to compare with the receiver.

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the `otherDate` is an [`NSDate`](/documentation/Foundation/NSDate) object and is exactly equal to the receiver, otherwise <doc://com.apple.documentation/documentation/Swift/false>.

## Discussion

This method detects sub-second differences between dates. If you want to compare dates with a less fine granularity, use [`timeIntervalSince(_:)`](/documentation/Foundation/NSDate/timeIntervalSince(_:)) to compare the two dates.
