title: Show Previous and next week dates
body: <p>I have 2 buttons( Previous and next ) for week. In between the previous and next week button needs to show week ending date (Fridays) for that week.
  I want to display previous week date from Sun 11/18 to Mon 11/26 when we click the previous week button. Same as the next week button click event to show from Mon 11/26" to Sun 12/2.
  How it possible to show? and how to take the week ending date (Fridays) for that week?</p>
