Check day of an ISO date

Question

I have a date field in ISO format like this: 2017-06-06T00:00:00 I'm looking for a way to find if the date string above represents Saturday or Sunday. I've read some post and all of them have a Date object format date and not an ISO date. I really appreciate your help

I thought calling `Date(string)` would try to parse it using the ISO format first... is that not the case? — Jon Skeet, Aug 10 '17 at 09:07
I've tried to parse it but it didn't return me the correct date — RamAlx, Aug 10 '17 at 09:08
So include that information in the question - show what you've tried and what went wrong. — Jon Skeet, Aug 10 '17 at 09:10

The Date constructor accepts (a simplified version of) ISO date strings:

const date = new Date('2017-06-06T00:00:00');
const day = date.getDay();

console.log(day); // 2 = Tuesday

const date = new Date('2017-06-06T00:00:00');
const day = date.getDay();
const days = ["Sun", "Mon", "Tues", "Wed", "Thur", "Fri", "Sat"];
console.log(days[day]);
