Why JavaScript Date object constructor doesn't work correctly?

Look at this code:

var date = new Date();
console.log(date);
// Tue Apr 30 2013 14:24:49 GMT+0430

var date2 = new Date(
    date.getFullYear(),
    date.getMonth(),
    date.getDay(), 0, 0, 0, 0
)
console.log(date2)
// Tue Apr 02 2013 00:00:00 GMT+0430

I simply extracted some date from today's date, and created another date with that data, and the result is another date, not today. What's wrong with JavaScript's Date object?

getDay() returns the day of the week (from 0 to 6), not the day of the month (1-31). the correct method is getDate():

var date = new Date();
console.log(date);
// Tue Apr 30 2013 14:24:49 GMT+0430

var date2 = new Date(
    date.getFullYear(),
    date.getMonth(),
    date.getDate(), 0, 0, 0, 0
)
console.log(date2)
// Tue Apr 30 2013 00:00:00 GMT+0430

.getDay() returns the day of the week (0-6), not day of the month. (It returns 2 for Tuesday)

Use getDate() - it will return 30
