Date.now() returns the number of milliseconds since January 1, 1970.

JavaScript stores dates as number of milliseconds since January 01, 1970. Zero time is January 01, 1970 00:00:00 UTC. One day (24 hours) is 86 400 000 milliseconds. Now the time is: milliseconds past January 01, 1970

The ISO 8601 syntax (YYYY-MM-DD) is also the preferred JavaScript date format:

This JavaScript program retrieves the current date and formats it in multiple ways (mm-dd-yyyy, mm/dd/yyyy, dd-mm-yyyy, dd/mm/yyyy). It uses the Date object to get the current day, month, and year, and then adds leading zeros if necessary to ...

The method Date.parse(str) can read a date from a string. The string format should be: YYYY-MM-DDTHH:mm:ss.sssZ, where:

Date.now() returns the number of milliseconds since January 1, 1970.

JavaScript stores dates as number of milliseconds since January 01, 1970, 00:00:00 UTC (Universal Time Coordinated). Zero time is January 01, 1970 00:00:00 UTC. Now the time is: milliseconds past January 01, 1970

There are many ways to format a date as a string. The JavaScript specification only specifies one format to be universally supported: the date time string format, a simplification of the ISO 8601 calendar date extended format.

The returned date's timestamp is the same as the number returned by Date.now(). ... An integer value representing the timestamp (the number of milliseconds since midnight at the beginning of January 1, 1970, UTC — a.k.a. the epoch). ... A string value representing a date, parsed and interpreted using the same algorithm implemented by Date.parse(). See date time string format for caveats on using different formats.

June 15, 2020 - It returns the value in milliseconds that represents the time elapsed since the Epoch. You can pass in the milliseconds returned from the now() method into the Date constructor to instantiate a new Date object:

// This example takes 2 seconds to run const start = Date.now(); console.log("starting timer..."); // Expected output: "starting timer..." setTimeout(() => { const ms = Date.now() - start; console.log(`seconds elapsed = ${Math.floor(ms / 1000)}`); // Expected output: "seconds elapsed = 2" }, 2000);

November 7, 2024 - Using Intl.DateTimeFormat, you can specify the desired locale and various options to format dates precisely as needed. There are more options you can use in the official documentation. When working with dates, it's essential to consider time zones, especially when dealing with global applications or time-sensitive information. JavaScript provides methods to handle time zones effectively:

July 11, 2025 - The code snippet generates a new Date object using the current timestamp from Date.now(). It then converts this date object to a string format using .toString() and logs it, displaying the current date and time. We have a complete list of Javascript Date Objects, to check those please go through this

By understanding these techniques, we can efficiently customize the format of a date according to our preferences. In this tutorial, we explored how to get dates in JavaScript, format them using different inbuilt methods, and covered the techniques that you can use for customized date formatting in JavaScript.
