Print Posts if Custom Field Value Date equal or greater than Today Date

In this example , suppose expiry date is (19 April 2021) AND also your Today Date is equal like(19 April 2021) or greater then Like Tomorrow date (20 April 2021),So You will get all the posts from today’s date,
Here, date format is (dd-mm-yyyy) as defualt (19-04-2021).
But, as your requirement format (‘d F Y’) like this (19 April 2021).
So, as per my example you can use this format Like
$today = strtotime(date(‘d F Y’));
But must remember that, Your posts Custon field return value As per your requirement date format.
