Date & Time in JavaScript

Let’s meet someone amazing today 😁, haha a new built-in object: Date. In Javascript, we can easily work with Date & Time using the Date class. To create an object of this type we use the new keyword.

 // Creating a Date object
    var dateObj = new Date();

    console.log(dateObj);

By doing this, we create an object with the current date and time formed by weekday, month, day, year, hours, minutes, seconds, and timezone. Now that's friggin precise 😝.

Methods of the Date object 😵

What is UNIX EPOCH?😰

The Epoch is present in most programming languages. We can consider it the starting point of counting the time. This is useful to do calculations with date and time.

Javascript uses the Unix Epoch, which is: Jan 1st, 1970, 00:00:00, UTC.

A Time Chart for reference 😅

How to calculate how many hours have passed since the Epoch? 😬

    var Obj = new Date();

    Obj = Obj.getTime();

    var hours = Obj / 3600000;

    console.log(Math.floor(hours));

Passing Argument to Date() 😷

We created date objects without passing any arguments, this is why they represented the current time but we can also use them with specific objects or better to say a specific number of objects.

var Obj = new Date(2021,1,24);
    console.log( Obj );

We can also pass strings as an argument and in different formats

• ISO date: "2020-03-18" (YYYY-MM-DD)
• Short Date: "03/18/2020" (MM/DD/YYYY)
• Long Date: "Mar 18 2020" or "18 Mar 2020"

I hope you guys have learnt and saved it for later reference
and if you found my grammatical mistakes then don't forget to comment them 😂
