How To Get First And Last Day Of Current Week When Days Are In Different Months?

For example, in the case of 03/27/2016 to 04/02/2016, the dates fall in different months. var curr = new Date; // get current date var first = curr.getDate() - curr.getDay(); var l

Solution 1:

The getDay method returns the number of the day in the week, with Sunday as 0 and Saturday as 6. So if your week starts on Sunday, just subtract the current day number in days from the current date to get the start, and add 6 days get the end, e.g.

function getStartOfWeek(date) {
  
  // Copy date if provided, or use current date if not
  date = date? new Date(+date) : new Date();
  date.setHours(0,0,0,0);
  
  // Set date to previous Sunday
  date.setDate(date.getDate() - date.getDay());
  
  return date;
}

function getEndOfWeek(date) {
  date = getStartOfWeek(date);
  date.setDate(date.getDate() + 6);
  return date; 
}
  
document.write(getStartOfWeek());

document.write('<br>' + getEndOfWeek())

document.write('<br>' + getStartOfWeek(new Date(2016,2,27)))

document.write('<br>' + getEndOfWeek(new Date(2016,2,27)))

Solution 2:

I like the moment library for this kind of thing:

moment().startOf("week").toDate();
moment().endOf("week").toDate();

Solution 3:

You can try this:

var currDate = new Date();
day = currDate.getDay();
first_day = new Date(currDate.getTime() - 60*60*24* day*1000); 
last_day = new Date(currDate.getTime() + 60 * 60 *24 * 6 * 1000);
