I need some help with converting unixtime to a specific format. Here is what I am currently working with:

var date = "2014-05-01";
var indexPie = Date.parse(date);

I need indexPie in yyyy-mm-dd format. What I do not understand is that when log

var newDate = new Date(indexPie);

The results is:

Wed Apr 30 2014 18:00:00 GMT-0600 (Mountain Daylight Time)

when it should be:

Thur May 01 2014 18:00:00 GMT-0600 (Mountain Daylight Time)

Why is new Date(indexPie) resulting in Apr 30 and how do I get my correct format of yyyy-mm-dd?

Any suggestions would be great. Thanks.

• javascript
• angularjs
• date
• datetime

• Because Wed Apr 30 2014 18:00:00 + 06 h == Thur May 01 2014 00:00:00 GMT. – dfsq Commented Jul 21, 2014 at 21:40
• I see....sorry I mocked in some data – user3845941 Commented Jul 21, 2014 at 21:41
• You get time in GMT-0600 timezone. – dfsq Commented Jul 21, 2014 at 21:42
• maybe it has something to do with your system time ... it works fine for me , here is the result Thu May 01 2014 01:00:00 GMT+0100 (GMT (heure d’été)) – Khalid Commented Jul 21, 2014 at 21:42
• That is odd why I get Apr 30 2014 18:00:00? I get that in JSFiddle as well – user3845941 Commented Jul 21, 2014 at 21:45

I resolved the issue with the following:

var date = new Date(indexPie);
var year = date.getUTCFullYear();
var month = date.getUTCMonth() + 1;
var day = date.getUTCDate();
var dateString = year + "-" + month + "-" + day;

You are expecting that the value in date variable: "2014-05-01" will be parsed as in local timezone, but actually it is parsed as in UTC.

You can convert the date from UTC to local timezone like this:

var newDate = new Date(indexPie + new Date().getTimezoneOffset() * 60000);
