Add A Year To Today's Date - javascript

I am trying to add a year to todays date. I am working in a system that does not allow you to use standard JavaScript.
For instance, to get todays date I have to use:
javascript:now();
I have tried:
javascript:now(+1);
I have never seen this before, but am in need of adding one year to todays date...
Has anyone seen getting current date this way before? And if so, how could I add a year?

Use the Date.prototype.setFullYear method to set the year to what you want it to be.
For example:
const aYearFromNow = new Date();
aYearFromNow.setFullYear(aYearFromNow.getFullYear() + 1);
console.log(aYearFromNow);
There really isn't another way to work with dates in JavaScript if these methods aren't present in the environment you are working with.

You can create a new date object with todays date using the following code:
var d = new Date();
console.log(d);
// => Sun Oct 11 2015 14:46:51 GMT-0700 (PDT)
If you want to create a date a specific time, you can pass the new Date constructor arguments
var d = new Date(2014);
console.log(d)
// => Wed Dec 31 1969 16:00:02 GMT-0800 (PST)
If you want to take todays date and add a year, you can first create a date object, access the relevant properties, and then use them to create a new date object
var d = new Date();
var year = d.getFullYear();
var month = d.getMonth();
var day = d.getDate();
var c = new Date(year + 1, month, day);
console.log(c);
// => Tue Oct 11 2016 00:00:00 GMT-0700 (PDT)
You can read more about the methods on the date object on MDN
Date Object

One liner as suggested here
How to determine one year from now in Javascript
by JP DeVries
new Date(new Date().setFullYear(new Date().getFullYear() + 1))
Or you can get the number of years from somewhere in a variable:
const nr_years = 3;
new Date(new Date().setFullYear(new Date().getFullYear() + nr_years))

This code adds the amount of years required for a date.
var d = new Date();
// => Tue Oct 01 2017 00:00:00 GMT-0700 (PDT)
var amountOfYearsRequired = 2;
d.setFullYear(d.getFullYear() + amountOfYearsRequired);
// => Tue Oct 01 2019 00:00:00 GMT-0700 (PDT)

I like to keep it in a single line, you can use a self calling function for this eg:
If you want to get the timestamp of +1 year in a single line
console.log(
(d => d.setFullYear(d.getFullYear() + 1))(new Date)
)
If you want to get Date object with single line
console.log(
(d => new Date(d.getFullYear() + 1, d.getMonth(), d.getDate()))(new Date)
)

In Angular, This is how you Calculate Date
today = new Date();
year = this.today.getFullYear();
month = this.today.getMonth();
day = this.today.getDate();
//To go 18 years back
yearsBack18= new Date(this.year - 18, this.month, this.day);
//To go to same day next year
nextYear= new Date(this.year + 1, this.month, this.day);

var d = new Date();
var year = d.getFullYear();
var month = d.getMonth();
var day = d.getDate();
var fulldate = new Date(year + 1, month, day);
var toDate = fulldate.toISOString().slice(0, 10);
$("#txtToDate").val(toDate);
output : 2020-01-02

//This piece of code will handle the leap year addition as well.
function updateExpiryDate(controlID, value) {
if ( $("#ICMEffectiveDate").val() != '' &&
$("#ICMTermYears").val() != '') {
var effectiveDate = $("#ICMEffectiveDate").val();
var date = new Date(effectiveDate);
var termYears = $("#ICMTermYears").val();
date = new Date(date.setYear(date.getFullYear() + parseInt(termYears)));
var expiryDate = (date.getMonth() + 1) + '/' + date.getDate() + '/' + date.getFullYear();
$('#ICMExpiryDate').val(expiryDate);
}
}

var yearsToAdd = 5;
var current = new Date().toISOString().split('T')[0];
var addedYears = Number(this.minDate.split('-')[0]) + yearsToAdd + '-12-31';

I am trying to get JavaScript to display tomorrows date in format (dd-mm-yyyy)
I have got this script which displays todays date in format (dd-mm-yyyy)
var currentDate = new Date()
var day = currentDate.getDate()
var month = currentDate.getMonth() + 1
var year = currentDate.getFullYear()
document.write("<b>" + day + "/" + month + "/" + year + "</b>")
Displays: 25/2/2012 (todays date of this post)
But how do I get it to display tomorrows date in the same format i.e. 26/2/2012
I tried this:
var day = currentDate.getDate() + 1
However I could keep +1 and go over 31 obviously there are not >32 days in a month
Been searching for hours but seems to be no answer or solution around this?
This should fix it up real nice for you.
If you pass the Date constructor a time it will do the rest of the work.
24 hours 60 minutes 60 seconds 1000 milliseconds
var currentDate = new Date(new Date().getTime() + 24 * 60 * 60 * 1000);
var day = currentDate.getDate()
var month = currentDate.getMonth() + 1
var year = currentDate.getFullYear()
document.write("<b>" + day + "/" + month + "/" + year + "</b>")
One thing to keep in mind is that this method will return the date exactly 24 hours from now, which can be inaccurate around daylight savings time.
Phil's answer work's anytime:
var currentDate = new Date();
currentDate.setDate(currentDate.getDate() + 1);
The reason I edited my post is because I myself created a bug which came to light during DST using my old method.
The JavaScript Date class handles this for you
var d = new Date(2012, 1, 29) // month is 0-based in the Date constructor
console.log(d.toLocaleDateString())
// Wed Feb 29 2012
d.setDate(d.getDate() + 1)
console.log(d.toLocaleDateString())
// Thu Mar 01 2012
console.log(d.getDate())

Method Date.prototype.setDate() accepts even arguments outside the standard range and changes the date accordingly.
function getTomorrow() {

tomorrow.setDate(tomorrow.getDate() + 1); // even 32 is acceptable
return `${tomorrow.getFullYear()}/${tomorrow.getMonth() + 1}/${tomorrow.getDate()}`;

I would use the DateJS library. It can do exactly that.
http://www.datejs.com/
The do the following:
var d = new Date.today().addDays(1).toString("dd-mm-yyyy");
Date.today() - gives you today at midnight.
The below uses a combination of Roderick and Phil's answers with two extra conditionals that account for single digit months/days.
Many APIs I've worked with are picky about this, and require dates to have eight digits (eg '02022017'), instead of the 6 or 7 digits the date class is going to give you in some situations.
function nextDayDate() {
// get today's date then add one
var nextDay = new Date();
nextDay.setDate(nextDay.getDate() + 1);
var month = nextDay.getMonth() + 1;
var day = nextDay.getDate();
var year = nextDay.getFullYear();
if (month < 10) { month = "0" + month }
if (day < 10) { day = "0" + day }
return month + day + year;
}
Use cases :
Date.tomorrow() // 1 day next
Date.daysNext(1) // alternative Date.tomorrow()
Date.daysNext(2) // 2 days next.
IF "tomorrow " is not depend of today but of another Date different of Date.now(), Don't use static methods but rather you must use non-static :

var tomorrow = new Date(Date.now() + 24 * 60 * 60 * 1000)

you can try this:

var day = givendate.getUTCDate()

How To add number of month into the given date in javascript?

I want to add month into the select date by the user.
startdate=document.getElementById("jscal_field_coverstartdate").value;
now I want to add 11 month from the above startdate. How to do that.
date format = 2013-12-01
Without the date format it is difficult to tell, however you can try like this
add11Months = function (date) {
var splitDate = date.split("-");
var newDate = new Date(splitDate[0], splitDate[1] - 1, splitDate[2]);
newDate.setMonth(newDate.getMonth() + 11);
splitDate[2] = newDate.getDate();
splitDate[1] = newDate.getMonth() + 1;
splitDate[0] = newDate.getFullYear();
return startdate = splitDate.join("-");
}
var startdate = add11Months("2013-12-01");
alert(startdate)
JSFiddle
If your startdate is in correct date format you can try using moment.js or Date object in javascript.
In Javascript, it can be achieved as follow:
var date = new Date("2013-12-01");
console.log(date);
//output: Sun Dec 01 2013 05:30:00 GMT+0530 (India Standard Time)
var newdate = date.setDate(date.getDate()+(11*30));
console.log(new Date(newdate));
// output: Mon Oct 27 2014 05:30:00 GMT+0530 (India Standard Time)
In above lines, I have used 30 days per month as default. So you will get exact 11 month but little deviation in date. Is this what you want ? You can play around this likewise. I hope it help :)
For more about Date you can visit to MDN.
You can do it like this:
var noOfMonths = 11
var startdate = document.getElementById("jscal_field_coverstartdate").value;
startdate.setMonth(startdate.getMonth() + noOfMonths)
Try this:
baseDate.setMonth(2);
baseDate.setDate(30);
noMonths = 11;
var sum = new Date(new Date(baseDate.getTime()).setMonth(baseDate.getMonth() + noMonths);
if (sum.getDate() < baseDate.getDate()) { sum.setDate(0); }
var m = newDate.getDate();
var d = newDate.getMonth() + 1;
var yyyy = newDate.getFullYear();
return (yyyy+"-"+m+"-"+d);
Notes:
Adding months (like adding one month to January 31st) can overflow the days field and cause the month to increment (in this case you get a date in March). If you want to add months and then overflow the date then .setMonth(base_date.getMonth()+noMonths) works but that's rarely what people think of when they talk about incrementing months.
It handles cases where 29, 30 or 31 turned into 1, 2, or 3 by eliminating the overflow
Day of Month is NOT zero-indexed so .setDate(0) is last day of prior month.

How to find the next 4 days from the current day using javascript

I found the current day as Mar 27 2012 ....
var currentday = currentday.format("mmm d yyyy");
I want to find the add three days with this value.
i.e. i need the output as Mar 30 2012.
I also need to find the starting and ending date of a calendar. i.e. Feb 26 2012 - Mar 31 2012 to display the current month as displaying in calendar month view.
Can any one help me on this please....
var currentday = new Date();
var nextDay = new Date();
nextDay.setDate(currentday.getDate() + 4);
//Set number of days you want to compute to
var days=4;
//Get current date or whatever date you want to compute from
var currentDate=new Date();
var nDaysFromNow=new Date();
nDaysFromNow.setDate(currentDate.getDate()+days);
You can add days using the getDate() function like so:
var someDate = new Date();
someDate = someDate.getDate() + 3;
See code below.. Hope it helps
var days = 4;
var next = new Date((new Date).getTime() + ((1000*3600*24) *days));

Simply! in dd.mm.yyyy format.
Date.prototype.NextDay = function (e) {
return new Date(this.getFullYear(), this.getMonth(), this.getDate() + ("string" == typeof e ? parseInt(e, 10) : e));

console.log(new Date().NextDay(1))

console.log(new Date().NextDay(2))

javascript: get month/year/day from unix timestamp

I have a unix timestamp, e.g., 1313564400000.00. How do I convert it into Date object and get month/year/day accordingly? The following won't work:
function getdhm(timestamp) {
var date = Date.parse(timestamp);
var month = date.getMonth();
var day = date.getDay();
var year = date.getYear();
var formattedTime = month + '/' + day + '/' + year;
return formattedTime;
}
var date = new Date(1313564400000);
var month = date.getMonth();
etc.
This will be in the user's browser's local time.
An old question, but none of the answers seemed complete, and an update for 2020:
For example: (you may have a decimal if using microsecond precision, e.g. performance.now())
let timestamp = 1586438912345.67;
And we have:
var date = new Date(timestamp); // Thu Apr 09 2020 14:28:32 GMT+0100 (British Summer Time)
let year = date.getFullYear(); // 2020
let month = date.getMonth() + 1; // 4 (note zero index: Jan = 0, Dec = 11)
let day = date.getDate(); // 9
And if you'd like the month and day to always be a two-digit string (e.g. "01"):
let month = (date.getMonth() + 1).toString().padStart(2, '0'); // "04"
let day = date.getDate().toString().padStart(2, '0'); // "09"
For extended completeness:
let hour = date.getHours(); // 14
let minute = date.getMinutes(); // 28
let second = date.getSeconds(); // 32
let millisecond = date.getMilliseconds(); // 345
let epoch = date.getTime(); // 1586438912345 (Milliseconds since Epoch time)
Further, if your timestamp is actually a string to start (maybe from a JSON object, for example):
var date = new Date(parseFloat(timestamp));
or for right now:
var date = new Date(Date.now());
More info if you want it here (2017).
Instead of using parse, which is used to convert a date string to a Date, just pass it into the Date constructor:
var date = new Date(timestamp);
Make sure your timestamp is a Number, of course.
