Question

I’m trying to get the last week date in JavaScript, without the time.

So for example, 10-02-2012, instead of 10-02-12 13:34:56 GMT.

Is there an easy solution out there for this?

Thank you!

Edit:

I’m trying to make this dynamic, so that the resulting variable is always one week before the current date. Here’s what I’ve done to calculate the today variable, if this helps or can be used!

var currentTime = new Date();
var month = currentTime.getMonth() + 1
var day = currentTime.getDate();
var year = currentTime.getFullYear();
var today = month + "-" + day + "-" + year;
alert(today)

Answer 1

I prefer something like this
​

function getLastWeek() {
  var today = new Date();
  var lastWeek = new Date(today.getFullYear(), today.getMonth(), today.getDate() - 7);
  return lastWeek;
}

var lastWeek = getLastWeek();
var lastWeekMonth = lastWeek.getMonth() + 1;
var lastWeekDay = lastWeek.getDate();
var lastWeekYear = lastWeek.getFullYear();

var lastWeekDisplay = lastWeekMonth + "/" + lastWeekDay + "/" + lastWeekYear;
var lastWeekDisplayPadded = ("00" + lastWeekMonth.toString()).slice(-2) + "/" + ("00" + lastWeekDay.toString()).slice(-2) + "/" + ("0000" + lastWeekYear.toString()).slice(-4);

console.log(lastWeekDisplay);
console.log(lastWeekDisplayPadded);

And if you’re using jQuery UI, you can do this instead of the manual steps to build the string

var lastWeekDisplay = $.datepicker.formatDate('mm/dd/yy', getLastWeek());

Or for today

var todayDisplay = $.datepicker.formatDate('mm/dd/yy', new Date());
