How to download only closed market data

[optimvsjag]

Hi team, I'm trying to download daily data only if market is closed.
I've this code:

• "last_date_df" is my last update date

start = (last_date_df + timedelta(days=1)).strftime('%Y-%m-%d')
end = (datetime.today() - timedelta(days=1)).strftime('%Y-%m-%d')
update_data = yf.download('AAPL', start=start, end=end, interval='1d')

With this code i've this date just now:
datetime.today is 2023-10-07 03:02 New York Time
end = 2023-10-06

But yfinance function only download data to 2023-10-05
Market is closed for 2023-10-06 and should can download this day data too, but I dont know why not works. Any idea or help to understand better how works?
Thanks a lot.

replace my last_date_df assignment with your own code

    import yfinance as yf
    import datetime as dt
    last_date_df = dt.datetime.strptime('2023-11-30', '%Y-%m-%d')

    today = dt.datetime.today()
    start = (last_date_df + dt.timedelta(days=1)).strftime('%Y-%m-%d')
    if dt.datetime.now().hour < 16:
        end = today.strftime('%Y-%m-%d')
    else:
        end = (today + dt.timedelta(days=1)).strftime('%Y-%m-%d')
    update_data = yf.download('AAPL', start=start, end=end, interval='1d')
