new Date(2014,1,1) converts to 1th february with momentJS

Question

Why does this declaration result in a momentJS object with Date 1th February 2014 ???

var startDate = moment(new Date(2014, 1, 1));

Has nothing to do with `momentjs`. [MDN Date](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date) *"**month:** Integer value representing the month, beginning with 0 for January to 11 for December."* — cookie monster, Mar 26 '14 at 20:07

Because the second argument is 0-11 in the Date object. (1 being Feb). Its not a MomentJS issue.

Change to new Date(2014, 0, 1)

because the month is 0 based. you would do

var startDate = moment(new Date(2014, 0, 1));

for jan.
