Date methods

In order to work with dates in JavaScript we use the built-in Date object. This object contains a lot of built-in functions to work with dates.

Creating dates

There are different ways to create a date. One way to create dates is by using the different constructors. You can see some examples here:

let currentDateTime = new Date();
console.log(currentDateTime);

This will log the current date and time, in this case:

2021-06-05T14:21:45.625Z

But, this way we are not using the built-in method, but the constructor. There is a built-in method, now(), that returns the current date and time, similar to what the no argument constructor does:

let now2 = Date.now();
console.log(now2);

This will log the current time, represented in seconds since January 1st 1970. This is an arbitrary date representing the Unix epoch. In this case:

1622902938507

We can add 1,000 milliseconds to the Unix epoch time:

let milliDate = new Date(1000);
