In JavaScript, the Date object represents a single moment in time in a platform-independent format. Date objects contain a number called a timestamp that represents milliseconds passed since the Unix Epoch on January 1, 1970, at 00:00:00 UTC.

const myDate = new Date('2023-22-11');
console.log(myDate.valueOf()); // Number of milliseconds till date from midnight 1st Jan 1970

Understanding the Date Object Output#

Consider the following timestamp: 2023-11-22T12:05:24.835Z. This output can be broken down into several components, each representing a different part of the date and time:

• Year: 2023
• Month: 11 (November)
• Day: 22
• Time: 12:05:24.835 (12 hours, 5 minutes, 24 seconds, and 835 milliseconds)
• Time Zone: The Z at the end indicates Zulu time, also known as Coordinated Universal Time (UTC).
