Dealing with dates and times in JavaScript is famously challenging. That’s why a library like Moment.js has almost 15 million weekly downloads on npm.
However, if you check the documentation of Moment.js, you will see that even they recommend some alternatives when it comes to modern development. One of the issues with Moment.js is the bundle size. If you need internationalization or time zone support, the bundle size can get quite large.
One alternative is the Day.js package, which is only 2kb.
Day.js is a minimalist JavaScript library that parses, validates, manipulates, and displays dates and times for modern browsers with a largely Moment.js-compatible API.
If you used Moment.js before, using Day.js will feel very comfortable for you.
In this article, we will take a look at the Day.js package with some examples of the most common functions you will use.
For our example, we will be working in a React application with JavaScript.
To get started with Day.js, install the package into your project.
npm install dayjs
Import dayjs
and you can now use it in your file.
import dayjs from 'dayjs';

Dealing with dates and times in Python can be a hassle. Thankfully, there’s a built-in way of making it easier: the Python datetime module.
datetime helps us identify and process time-related elements like dates, hours, minutes, seconds, days of the week, months, years, etc. It offers various services like managing time zones and daylight savings time. It can work with timestamp data. It can extract the day of the week, day of the month, and other date and time formats from strings.

tl;dr: We are looking for feedback on the Temporal proposal. Try out the polyfill, and complete the survey; but don’t use it in production yet!
JavaScript Date
is broken in ways that cannot be fixed without breaking the web. As the story goes, it was included in the original 10-day JavaScript engine hack and based on java.util.Date, which itself was deprecated in 1997 due to being a terrible API and replaced with a better one. The result has been for all of JavaScript’s history, the built-in Date
has remained very hard to work with directly.
Starting a few years ago, a proposal has been developing, to add a new globally available object to JavaScript, Temporal
. Temporal is a robust and modern API for working with dates, times, and timestamps, and also makes it easy to do things that were hard or impossible with Date
, like converting dates between time zones, adding and subtracting while accounting for daylight saving time, working with date-only or time-only data, and even handling dates in non-Gregorian calendars. Although Temporal has “just works” defaults, it also provides fine-grained opt-in control of overflows, interpreting ambiguous times, and other corner cases. For more on the history of the proposal, and why it’s not possible to fix Date
itself, read Maggie Pint’s two-part blog post “Fixing JavaScript Date”.
For examples of the power of Temporal, check out the cookbook. Many of these examples would be difficult to do with legacy Date
, particularly the ones involving time zones. (We would have put an example in this post, but the code might soon become stale, for reasons which will hopefully become clear!)

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.
JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.
JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.
Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.
In JavaScript, ‘document.write‘ is used to represent a string on a browser.
<script type="text/javascript">
document.write("Hello World!");
</script>
<script type="text/javascript">
//single line comment
/* document.write("Hello"); */
</script>
