How Can I check the computer's date format in Python?

please help me. How can I check the computer's date format in Python, if the date format is dd/mm/yyyy then print number 1, if mm/dd/yyyy then print number 2. Thank you for your help.

I asked Copilot for help before, but it didn't work properly.

from dateutil import parser

def validate_date_format(date_str):
    try:
        parser.parse(date_str)
        return 1
    except ValueError:
        return None

input_date = input("Enter the date: ")
result = validate_date_format(input_date)
if result:
    print(f"Date format: {result}")
else:
    print("Invalid date format.")

It will needed to be handled seperately for Window's vs macOS/Linux,

import locale
import platform
import ctypes

def get_windows_date_format() -> int:
    LOCALE_SSHORTDATE = 0x1F  # Constant to get the short date format
    buffer_size = 80
    buffer = ctypes.create_unicode_buffer(buffer_size)

    # Call Windows API to get the short date format
    ctypes.windll.kernel32.GetLocaleInfoW(
        ctypes.windll.kernel32.GetUserDefaultLCID(),
        LOCALE_SSHORTDATE,
        buffer,
        buffer_size
    )
    
    short_date_format = buffer.value

    # Determine the format based on the leading pattern
    if short_date_format.startswith('M'):
        return 2  # mm/dd/yyyy format
    elif short_date_format.startswith('d'):
        return 1  # dd/mm/yyyy format
    else:
        return 0  # Unknown or different format

def get_unix_date_format() -> int:
    # On macOS and Linux, we rely on locale settings
    locale.setlocale(locale.LC_TIME, '')
    formatted_date = locale.nl_langinfo(locale.D_FMT)
    
    # Guess format based on known patterns
    if '%d' in formatted_date and '%m' in formatted_date:
        return 1  # dd/mm/yyyy format
    elif '%m' in formatted_date and '%d' in formatted_date:
        return 2  # mm/dd/yyyy format
    else:
        return 0  # Unknown or different format

def check_date_format() -> int:
    if platform.system() == "Windows":
        return get_windows_date_format()
    else:
        return get_unix_date_format()

result = check_date_format()

if result == 1:
    print("Date format is dd/mm/yyyy (1)")
elif result == 2:
    print("Date format is mm/dd/yyyy (2)")
else:
    print("Unknown or different date format")
