i really stuck at this date. Let say today is 01 20 2021, and i want to add 14 day later to get expired date. so for the expired date should be 02 03 2021, but i only get 01 03 2021. Can anyone help me on this. Thanks
this is my code
var today = new Date();
var monthIndex = today.getMonth()+1;
var year = today.getFullYear();
var addday = new Date(new Date('1.20.2021').getTime()+(14*24*60*60*1000));
var nextDay = addday.getDate();
var nextMonth = monthIndex;
console.log('day',day)
return nextMonth+'.'+nextDay+'.'+year
//the return that I want is 2.03.2021
You didnt update the value for monthIndex. You must use:
var nextMonth = addday.getMonth()+1;
Just use Date.setDate function for this.
// new Date('1.20.2021') => Jan 20 2021
const dateStr = '1.20.2021';
const [mm, dd, yyyy] = dateStr.split('.');
const today = new Date(yyyy, +mm-1, dd);
// add 14 days
const newDate = new Date(new Date(today).setDate(today.getDate() + 14));
console.log(`Today: ${today}`);
console.log(`New Date: ${newDate}`);
console.log(newDate.getMonth() + 1 + '.' + newDate.getDay() + '.' + newDate.getFullYear());
