Why this is giving different month

The following code below:

var unixDate = new Date('07/28/2010');
    var unixMonth = unixDate.getMonth();
    var unixDay开发者_Go百科 = unixDate.getDate();
    var unixYear = unixDate.getFullYear();
    alert(filterDate.value);
    alert(unixMonth);
    alert(unixDay);
    alert(unixYear);

should give me month 07 but it alerts 06.... why's that?

Months are zero based. Just do +1. See also Date.getMonth() at MDC:

The value returned by getMonth is an integer between 0 and 11. 0 corresponds to January, 1 to February, and so on.

The months are 0-based, 0=January

http://www.w3schools.com/jsref/jsref_getMonth.asp

.getMonth returns a zero indexed month. So, 0 = January, and 11 = December.

Use:

var unixMonth = unixDate.getMonth() + 1;

.getMonth returns a zero indexed month.

0  = January
11 = December

More Info

The getMonth() method returns the month (from 0 to 11) for the specified date, according to local time.

Note: January is 0, February is 1, and so on.

My guess would be that 0 = January and thus your enumeration is slightly off.
