My server sends current server time, and I need to handle them with JS.

var currentDate = new Date(someYear, someMonth, someDay, 12);
console.log(currentDate.getDate()+'.'
            +currentDate.getMonth()+'.'
            +currentDate.getFullYear()
        ); //8.4.2016 - this is right, today is 8th April of 2016
console.log(currentDate.getDay()); // 0. But today is Friday, not Monday!

Why currentDay.getDay() returns wrong number?

@Hacketo sorry, this was a typo. – WhilseySoon Apr 08 '16 at 07:45

`getMonth` is 0 index based so 4 is `May` – Hacketo Apr 08 '16 at 07:45
@Hacketo Why on Earth someone made months to start from '0'? Thank you for the solution. – WhilseySoon Apr 08 '16 at 07:47
With a 0 index based value you can easily use an array see : http://stackoverflow.com/questions/15799514/why-does-javascript-getmonth-count-from-0-and-getdate-count-from-1 – Hacketo Apr 08 '16 at 07:48
Month 4 = May. Months start counting from 0. That makes it Sunday, which is the first day of the week (day 0) – Mario Garcia Apr 08 '16 at 08:02
