date-fns VS js-joda

In past i used Moment, but I read that we should avoid to use it for future projects. I read someone suggested to use Datejs, but it doesn't seems to be updated, last time was 8 years ago. Currently I'm thinking to use Luxon but I someone suggest Date-fns also.

date-fns : Date handling

Thanks! I used date-fns for the calendar

I've used this before and I like it more

The default date constructor does a really great job at parsing in most cases and things like addition/subtraction along with many other common operations are usually just simple math. If you really want to abstract that use date-fns where most date operations are tree shakable to be left with just a few lines of code.

date-fns and mitt (event emitter) are also frequent helpers, but I'm considering dayjs and nanoevents for these cases.

We all know the pain of working with dates in Javascript. It needs to be more explicit, has almost no method, and could not be more clunky. For example, to create the Date January 1, 2023, you have to write a new Date (2023, 0, 1), which can be confusing for beginners, and overall just not that clear. And because of these reasons, the community has made many libraries that attempt to make Date easier to work with over the past years. Like momentjs or Date-fns. But the good news is that you won't need these third-party libraries any longer. The Temporal Date API in Javascript attempts to completely replace the Date object and fix all of the issues we generally face when working with dates.

Next we're going to install any additional dependencies we need. In our case, we're just going to need date-fns which is a library that makes it trivial to work with datetimes in JavaScript.

Obligatory plug for date-fns. https://date-fns.org/

js-joda

So first, a simple example of how this works. Using our "What is your birthday" example, we can mock up this code. Note: I'm using TypeScript because it enforces the concepts at compile time, but the JsJoda library itself enforces the concepts at runtime so that we get the best of both.

Dealing with human dates is non-trivial thanks to localization. The easiest thing to do is to start with something zone agnostic (like UTC or epoch) do your date calculation, and then shift that into the locale you want. date-fns is fine for basic date math, but if you want something more robust, with a more cohesive API, I'd recommend js-joda.

How come the js-joda library is never mentioned in discussions about javascript date/time libraries? its API is perfect and it has been around forever. but instead the community seems to keep inventing more and more new datetime libraries. i don't understand why js-joda seems to be ignored

I've been getting by with js joda. Temporal is a welcome addition.

Support for the domain models LocalDate, LocalDateTime, ZonedDateTime, Instant, Duration and Period. Also, supports IANA timezone, adding the plugin @js-joda/timezone you'll have access to the IANA timezone database with all the timezones available.
