Html Countdown Development Tutorials, Guides & Insights

let date = new Date();
let count;
if (date.getDate() >= 20) {
    count = date.getMonth() + 2; // Move to the next month
} else {
    count = date.getMonth() + 1; // Use the current month
}

let year = date.getFullYear(); // Get the current year
let date_str = `${year}-${count.toString().padStart(2, '0')}-20T23:59:59`; // Format the deadline as YYYY-MM-20
let deadline = new Date(date_str);

• We check if the current day is greater than or equal to the 20th. If true, the deadline is set to the 20th of the next month; otherwise, it’s set to the 20th of the current month.
• The deadline is formatted as YYYY-MM-20T23:59:59, ensuring the countdown ends at midnight on the 20th.
