title: How to get the date ranges of a given week number in JS
body: <p>I need to know the exact months that a week falls in if that week happens to be in 2 consecutive months. For example 52nd week of 2016 falls in Dec 2016 and January 2017.Also 5th week of 2017 starts on 30th January - 5th February 2017.</p>
  
  <p><strong>So given a week number in a year, can I get the months it falls in.</strong> I need to know if there is any JS library that can easily achieve this. </p>
  
  <p><em>I know I can get a week number from a specific date value but have not seen a way to get a range of dates that date falls in so that I can derive the months from there</em>.If momentJS or any other lib can do this, how can I use them to achieve this? </p>
  
  <p>Thanks in advance</p>
