Using variables in Javascript to manipulate the Date object

Question

Using variables in Javascript to manipulate the Date object

Here is my JavaScript code snippet:


var earlierdate = new Date(2012, 09, 22);
alert(earlierdate.getDay());

var date2 = new Date('2012, 09, 22');
alert(date2.getDay());

The issue I am facing is that the first alert displays 1 or Monday (incorrect) while the second one displays 6 or Saturday (correct). When I try to use variables instead of hard-coded values like this:


var date1 = new Date(a, b, c);
alert(date1.getDay());

I am unable to figure out the correct syntax. I have tried several variations without success.

Any help would be greatly appreciated. Thank you!

Answer №1

month

This is an integer value that represents the month, with January as 0 and December as 11.

So if you are referring to September, your code should look like this:

var earlierdate=new Date(2012, 8, 22);

//Method 1
var currentDate = new Date();
currentDate.setFullYear(2010, 0, 14);

//Method 2 (Simpler)
var currentDate = new Date(2010, 0, 14);

Using either of these methods will update the date to January 14th, 2010.
