# IsDateObject

Determine whether a given value or variable reference is a date or dateTime object.

Note that date strings, such as `2021-01-01` and timespans returned from `createTimespan()` are NOT date objects. The former are strings and the latter are numeric values.

## Method Signature

```
IsDateObject(value=[any])
```

### Arguments

| Argument | Type  | Required | Description                        | Default |
| -------- | ----- | -------- | ---------------------------------- | ------- |
| `value`  | `any` | `true`   | Value to test for date object-ness |         |

## Examples

### Check if date is a date OBJECT, not just a date string

```java
<bx:script>
	date = IsDateObject( now() );
	writeOutput( "Can string be converted to a date/time value : " & date );
</bx:script>

```

Result: Can string be converted to a date/time value : YES
