I want to display the date of last 6th week:

Output:

Answer 1

Use Date.setDate() and subtract number of days from current date

 var date = new Date(); var d = date.getDate(); var numOfWeeks = 6; date.setDate(d - (numOfWeeks * 7)); console.log(date); 

Answer 2

Assuming by last 6th week, you mean exactly 6 * 7 days ago (42).

You can modify the date instance using the setDate method, passing it the current instance's getDate subtracted by 42 days. For example:

var d = new Date();
d.setDate(d.getDate() - 42);
