You would research how to work with dates with JavaScript, among a few other things.

Here is a working demo for you. It is not guaranteed to be fit for purpose or covered by warranty. Use at your own risk!

/*
Today's date: 2024-10-18
Expires tomorrow: 2024-10-19
*/

// Get today's date
var today = new Date();
var year = today.getFullYear().toString();
// Extract the month... Months are zero indexed, so add one!
var month = ("0" + (today.getMonth() + 1)).slice(-2);
var date = ("0" + today.getDate()).slice(-2);
var yyyymmdd = year.toString() + month.toString() + date.toString();
// Convert the string back to a number
yyyymmdd = parseInt(yyyymmdd);

// Conditional
if (yyyymmdd < 20241019) {
    // Add your code below. Remove the following alert...
    alert("Pass");
} else {
    // Do nothing on fail. Remove the following alert...
    alert("Fail");
}
