Moment js giving incorrect week

Question

Here's my javascript

dt = moment("2016-01-01");
console.log(dt.week());

This gives week as 1

but when I refer to bootstrap calendar then it shows week as 53 of last year

can someone tell which is correct moment or bootstrap calendar? Also why?

PS - datepicker I am using is ui.bootstrap.datepicker from https://angular-ui.github.io/bootstrap/

经过一番谷歌搜索，我发现在我的情况下使用isoWeek()给出了正确的周数。
