date-fns VS moment-timezone

// Prevent the date to lose the milliseconds when passed to new Date() in IE10 return new (argument.constructor as GenericDateConstructor)( +argument, ); // Source: https://github.com/date-fns/date-fns/blob/5c1adb5369805ff552737bf8017dbe07f559b0c6/src/toDate/index.ts#L46

For the longest time working with dates in JavaScript was a huge pain. That’s why libraries such as moment.js or date-fns are so popular. A lot of times I’d reach for these libraries when working with relative time formatting, but since late last year we’ve had pretty great browser support for the RelativeTimeFormat() method. In my mind, relative dates are just more visually appealing, especially for working with dates internationally. Dates like "5 days ago" or "in 2 months" are far more intuitive for users than 12/12/2023, or 03/11/2027. Folks in the US will see that as March 11, 2027, whereas the rest of the world will see that as November 03, 2027. What a nightmare.

8. Date-fns - Simplifying Time Manipulation ⏳

I work with date-fns and date-fns-tz

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.

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.

moment-timezone is pretty great. However the moment library is no longer maintained, and there's some complications to its use due to it being mutable. Still works great though.

It was actually much easier to make than I thought it would be, thanks to Moment.

Otherwise... https://momentjs.com/timezone/

The clock is in Javascript. Time zones in JavaScript historically are non-trivial since everything is based on the client clocktime. Fortunately, there is moment.js and moment-timezone-with-data.js that vastly simplify getting the current time at the NYSE. The clock keeps ticking correctly irregardless of which tab is active. I find the clock to be also functional since the WSBoy is worn over where I would usually be wearing my watch.

I used the Moment-Timezone library, which returns, well, all the timezones! Super easy to get started with, just add using npm or yarn to add it, and then add import moment from 'moment-timezone'; to the top of your file.
