You are given a code snippet that includes a function, which calculates the current date and time and formats it in a specific way. Your task is to complete the function, so that it returns the formatted date as per the provided format.

Write a function `format_date()` that takes no parameters. The function should calculate the current date and time and return the formatted date in the format "YYYY-MM-DD".

**Example**

Input:
```
format_date()
```
Output:
```
"2022-01-01"
```

**Notes**
- You may assume that the code snippet is executed in a valid Python environment where the required modules are imported.
- The current date and time should be calculated based on the system clock when the function is called.

Sure, I can help you with that. Here's the Python function `format_date()` that calculates the current date and time in the ISO format ("YYYY-MM-DD") and returns it.

```python
import datetime

def format_date():
    # Get the current date and time
    current_datetime = datetime.datetime.now()

    # Extract only the date part (without time): datetime.datetime(2022, 1, 1, 0, 0, tzinfo=datetime.timezone.utc)
    current_date = current_datetime.date()

    # Convert the date to a string in the ISO format (YYYY-MM-DD): '2022-01-01'
    iso_formatted_date = current_date.isoformat()

    return iso_formatted_date
```

When you call this function, it will return the current date in the ISO format, which is what you specified.

Example usage:

```python
>>> format_date()
'2022-01-01'

>>> import datetime
>>> datetime.datetime.now().date().isoformat()
'2022-01-01'
```

Both of these would give the same output, since `datetime.datetime.now().date()` returns the current date object, and `.isoformat()` formats it as a string in the ISO format.

Sure, I can help you with that. Here's a Python function that uses the `datetime` module to get the current date and time, and then formats it in the "YYYY-MM-DD" format:

```python
from datetime import datetime

def format_date():
    current_date = datetime.now()
    formatted_date = current_date.strftime("%Y-%m-%d")
    return formatted_date
```

When you call `format_date()`, it will return the current date in the format "YYYY-MM-DD". Please ensure that the `datetime` module is available in your Python environment. It's a part of the standard library, so it should be available by default.
