date-fns VS moment-timezone

datefns is an alternative library that has a different philosophy. Rather than using a different type to represent dates, it has you continue using native dates, but provides tons of functions to do common tasks like parsing, formatting and date math.

Good job creating a library. I'd would only like to know what benefit this library provides over more established libraries, such as date-fns? https://date-fns.org/

date-fns is a lightweight library that works with built-in Dates and can perform arithmetic.

Definitely also worth mentioning is date-fns

We are using three libraries inside our projects, which are moment Moment.js, Day.js, and date-fns.

I'd consider using a library to help you out. Maybe something like https://date-fns.org, you could combine isBefore and isAfter to create a isInRange. Once you have that you can loop though your dateArr and for each entry, check if it's in any of your given ranges then increment the count.

OT: moment.js is deprecated, if u can, use date-fns.

Web-site:https://date-fns.org/ Github page: https://github.com/date-fns/date-fns Demo: – License: MIT Github stars: 22.8k Contribution guideline: Yes Date-fns provides the most comprehensive, yet simple and consistent toolset for manipulating JavaScript dates in a browser & Node.js. It works well with modern module bundlers such as webpack, Browserify, or Rollup. Date-fns is built using pure functions and always returns a new date instance instead of changing the passed one. With the support of an amazing community, date-fns has dozens of locales.

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.
