Is It DST?

While looking for an easy way to figure out whether or not it is currently DST, you may have come across isdst. One thing about this package is that its a lil old (though nothing is wrong with that), is synchronous, and doesn't actually extend the Date class (more convenient).

FAQ

Q: isdst exists, why should I use this?
A: It's asynchronous, extends the Date class, and has typescript support.

Q: Why are you modifying the date class?
A: I'm not modifying the Date class, simply extending it. This is common-practice and is not modifying the actual Date class.

Q: i dOn'T wANt iT eXTeNdInG tHe dAtE OBjEcT
A: lulwut, its just the date object. If you dont want a class extention (for some reason), you can use isdst.

Q: This shouldn't be a library.
A: You're the one looking for how to judge whether or not it is DST, you are in no space to criticize the work of isitdst or isdst.

Q: Poop?
A: Pee

Usage

Ok, so this is very simple, simply import it like this:

const DateDST = require('isitdst');

You can now use the DateDST class as a normal Date class, but calling isDST() will return a boolean of whether or not it is currently Daylight savings time, like this:

const DateDST = require('isitdst');

var date = new DateDST(2069, 4, 20);

console.log(date.isDST());

Thats all!
