I have no idea where to start with this one:
I have a database that stores postID and Date.
What I want to do is have my website auto delete all rows where Date is less than today. This script can't have any user input at all. No button clicks, nothing. The script must run every day at midnight.
I've been looking all over the place for something that does this and I've found absolutely nothing.

To delete all rows older than 30 days, you need to use the DELETE with INTERVAL. Use < now() i.e. less than operator to get all the records before the current date.
To delete rows in a MySQL table, use the DELETE FROM statement: DELETE FROM products WHERE product_id=1; The WHERE clause is optional, but you'll usually want it, unless you really want to delete every row from the table.
If you want a row to disappear from a view, you need to either delete the data from the real tables behind the view, or alter the view-creating SQL so that that particular row won't be shown in the view.
The Delete query in MySQL can delete more than one row from a table in a single query. This proves to be advantages when removing large numbers of rows from a database table. Once a Delete row in MySQL row has been deleted, it cannot be recovered.
You can use PHP script and use cron job on your cpanel.
Example:
cronjobcommand.php
<?php
include 'your_db_connection';
mysql_query("DELETE FROM your_table_name WHERE Date < NOW()");
?>
I have attached a screenshot below for your more reference.

For those out there who are on a shared hosting, like 1and1's, and can't use cron, here are 2 alternatives :
mysql events enable you to place a time trigger on mysql, which will execute when you'll want, without having to be fired by any kind of user input
if you cannot create mysql events because you're on 1and1 :(, an alternative is to use webcron
You just need to tell webcron the url of the php script you'd like to be run, and they'll trigger it for you at the intervals you want
