To get a JavaScript date / time format you can use the Date (), which contains the current time in a readable format. You can also create new Date () objects with different timestamps and get time Unix current using the getTime () method .

Managing dates and times is a crucial part of planning. In JavaScript, for example, you may need to create a dynamic copyright date, calendar, or list of events and their times, which involves the use of date / time to some extent.

To work with time in JavaScript, you can use the date object and its methods. The Date object allows you to store the date and time and format the date and time according to your specific needs.

In this tutorial, we will explore the basics of creating a JavaScript timestamp using data. We will also discuss how to format date and timestamps in JavaScript and how to get UTC time values.

JavaScript timestamp object

Date object is used in JavaScript to store date and time. Without arguments, the Date object creates an object with the date and time. Here is an example of the Date object used to get the date and time:

In our code, we declare a variable called "currentTime" to which we assign a Date object. Then we print the variable "currentTime" to the console. Our code returns the following message:

Wed Feb 5, 2020 11:18:21 GMT + 0000 (Greenwich Mean Time)

like you can see, our code returned the date and time in a readable manner. We can break the result of our Date object into a few components:

  • day: Wed
  • Month: Feb
  • day: 14
  • Year: 2020
  • Time: 11
  • Minutes: 18
  • Second: 21
  • Time zone: GMT + 000 (Greenwich Mean Time)

However, while the date object returns this value, JavaScript understands dates and times across Unix time. the Unix time is a value that represents the number of milliseconds that have elapsed since midnight January 1, 1970, and is universal standard for the storage time in the programming

If we want to get a Unix JavaScript timestamp , we can do it using the getTime () method like this:.

Our code returns: 1580901774643 . While this number is not as attractive as the information we received above, it does mean exactly the same.

Creating new given objects by existing timestamps

So far we have been discussing how to create a low Date object at the moment. However, we can also create a Date object based on an existing JavaScript timestamp.

This can be useful if you already have a date value, but want to manipulate it using the JS Date object. For example, you might have a Unix timestamp that you want to display in the extended version of the time shown above (the one that shows the day, time, time zone, and other relevant information).

You can create a new date object from an existing timestamp in two ways. You can use the date to create a new object based on:

  • An existing Unix timestamp (new date (timestamp))
  • A date string (new date (string date))
  • a specific date and time (new date (year, month, day, hour, minute, second, millisecond))

Here is an example of each of these methods in action:

new date (9231925020);

new date ("April 17th, 1970 21:25:25");

new date (1970, 3, 17, 21, 25, 25, 0);

Each of these examples creates a date object using the same information. So if we print the time using one of these data objects and the getTime () function like we did earlier, we’ll get this response:

Fri April 17, 1970 21:25:25 GMT + 0100 (Greenwich Mean Time )

It is worth noting that in the last method you can specify the year, month, day, hours, minutes, seconds and milliseconds, every missing values ‚Äã‚Äãwill be set to 0. Additionally, ours month is & ldquo ;. 3 " because the JavaScript Date object accounts for " 0 " for months

Retrieving the date

that we have a Date object, we can retrieve part of the date or time we need. we can use the get in JavaScrip t to return parts of the date of report to the local time area The methods of this day, we can use to retrieve the date.

Let’s create a new date object January 1, 2020:

const January2020 = new Date (2020, 1, 1);

Now if we use above methods for year, month and day of month we will get the following:

We could run one of the date methods discussed earlier on our timestamp to get specific parts of the time

We can also use our Date object to compare times in JavaScript. So if we wanted to see if it was 2020, we could use the following code:

Since its 2020 that this article is written, our code returns: "It is 2020" We could also perform more advanced comparison methods, such as comparing the year and the day by using the same approach as we did above - above

UTC Methods

The values ‚Äã‚Äãreturned by the day fetch functions discussed above will be based on the time zone parameters local time schedule. If you want to get UTC timestamps, which calculate time based on Coordinated Universal Time - you must add "UTC" after the word "get" in the functions above

here & rsquo; is an example methods of the getHours () and getUTCHours () used to get the current time and time in the UTC time zone:

Our code returns the following elements:

11

11

This code displays both the time in the time zone and the time in the UTC time zone. If you are currently in UTC, these numbers will be the same (as above).

Using UTC can be useful as it is an internationally accepted standard and is often used when creating a website or application that depends on multiple time zones.

Conclusion

Time is an important part of JavaScript that you are likely to encounter often when recoding. In this tutorial, we have discussed how to create a Date object to store the current time. We also discussed how to create custom Date objects based on specific timestamps, date strings, and times, and explored JavaScript’s built-in date retrieval methods.

You are now equipped with the skills to retrieve and manipulate JavaScript like an expert timestamps!

I was preparing for my coding interview, thanks for clarifying this - Javascript Date Format in Python is not the simplest one. I am just not quite sure it is the best method
