Question

I need to find out the previous year date from current date and then set as minDate in jQuery UIdatepicker in javascript

My date formaqt is dd-mm-yy

<

Answer 1

I had the same problem with Angular 7. Following is my solution in typescript.

new Date(new Date().setFullYear(new Date().getFullYear() - 1))

Answer 2

For strings:

curdate.substr(0, 6)+(curdate.substr(6)-1);

If you'd use a Date object, you could easily subtract a year with the set[Full]Year method.

Answer 3

Try this

var d = new Date();
var pastYear = d.getFullYear() - 1;
d.setFullYear(pastYear);
console.log(d);

Answer 4

To avoid the Date object (if that is what OP wishes):

var currDate = '25-07-2012';
var dateParts = currDate.split('-');
dateParts[2] = parseInt(dateParts[2], 10) - 1;
alert(dateParts.join('-'));​

Answer 5

  function getTodayDate() {
        var today = new Date();
        var dd = today.getDate();
        var mm = today.getMonth() + 1; //January is not 0!
        var yyyy = today.getFullYear();
        if (dd < 10) { dd = '0' + dd }
        if (mm < 10) { mm = '0' + mm }
        today = yyyy + '-' + mm + '-' + dd;
        return today;
    };
    function getYearAgo(){
    var lastYear = new Date();
    var dd = lastYear.getDate();
    var mm = lastYear.getMonth() + 1; //January is not 0!
    var yyyy = lastYear.getFullYear(getTodayDate) - 1;
    if (dd < 10) { dd = '0' + dd }
    if (mm < 10) { mm = '0' + mm }
    lastYear = yyyy + '-' + mm + '-' + dd;     
    return lastYear;
    }

Answer 6

Datepicker allows you to put a number as the minDate option, and it uses that as an offset from the current date. So you can write:

minDate: -365

to specify 1 year ago. This doesn't take leap years into account, though.
