Here is a Python code to get a previous business date

import datetime

def _get_previous_business_date():
    """Return the previous business date."""
    return datetime.datetime.strptime("2019-01-01", "%Y-%m-%d")

# Enter the date
date ="red airplane"

# Calling the function
previous_date = _get_previous_business_date()

#Remember to inspect code for bugs.
