Add one day to date in javascript

I am sure that a lot of people asked this question but when I checked the answers it seems to me that they are wrong that what I found

I know that .getDate() return from 1-31 but Does the browser or the javascript increase only the day without updating the month and the year ?

and in this case Should I write an algorithm to handle this ? or there is another way ?

Note that Date.getDate only returns the day of the month. You can add a day by calling Date.setDate and appending 1.

JavaScript will automatically update the month and year for you.

EDIT: Here's a link to a page where you can find all the cool stuff about the built-in Date object, and see what's possible: Date .

The Date constructor that takes a single number is expecting the number of milliseconds since December 31st, 1969 .

Date.getDate() returns the day index for the current date object. In your example, the day is 30 . The final expression is 31 , therefore it's returning 31 milliseconds after December 31st, 1969 .

A simple solution using your existing approach is to use Date.getTime() instead. Then, add a days worth of milliseconds instead of 1 .

For example,

Please note that this solution doesn't handle edge cases related to daylight savings, leap years, etc. It is always a more cost effective approach to instead, use a mature open source library like moment.js to handle everything.

There is issue of 31st and 28th Feb with getDate() I use this function getTime and 24*60*60*1000 = 86400000

Use this function:

Example as below:

var dateWith31 = new Date("2017-08-31"); var dateWith29 = new Date("2016-02-29"); var amountToIncreaseWith = 1; //Edit this number to required input console.log(incrementDate(dateWith31,amountToIncreaseWith)); console.log(incrementDate(dateWith29,amountToIncreaseWith)); function incrementDate(dateInput,increment) { var dateFormatTotime = new Date(dateInput); var increasedDate = new Date(dateFormatTotime.getTime() +(increment *86400000)); return increasedDate; }

use this i think it is useful for you

I think what you are looking for is:

Also, you can have a look at Moment.js

A javascript date library for parsing, validating, manipulating, and formatting dates.

i know it's been long time since this is posted but here's my answer

This will help you...

add one day in javascript in one line

NB: if you want to add a specific number of days ... just replace 1 with the number of days you want

console.log(new Date(new Date().setDate(new Date().getDate() + 1)))

Just for the sake of adding functions to the Date prototype:

In a mutable fashion / style:

you just forgot the return – Vixed Sep 8, 2020 at 17:53

If you don't mind using a library, DateJS ( https://github.com/abritinthebay/datejs/ ) would make this fairly easy. You would probably be better off with one of the answers using vanilla JavaScript however, unless you're going to take advantage of some other DateJS features like parsing of unusually-formatted dates.

If you're using DateJS a line like this should do the trick:

You could also use MomentJS which has similar features ( http://momentjs.com/ ), however I'm not as familiar with it.

The below will add a single day to a current time. I believe this will handle daylight saving times, etc.

// just replace 1 with the number of days you want

let tomorrow = new Date(new Date().getTime() + ((1 * 24) * 60 * 60 * 1000)); console.log("tomorrow ", tomorrow)

How to Add Days to JavaScript Date

JavaScript provides the Date object, which enables you to view and manipulate date and time . Developers work with date and time frequently and often want to add some days to an existing date object. For example, consider the situation you want to show a deadline. You want to show the client that the deadline is five days after this day. In this tutorial, you will learn an easy way of adding days to Javascript Date with setDate() and getDate() inbuilt functions to set and get the day of the month represented by the Date object.

Here is a utility function that creates a date object and adds seven days to it, to have a date object representing next week.

Date Object

The Date is a built-in object in JavaScript. When you create a Date object with the New Date(), a set of methods become available to operate on it. These methods allow getting and setting the year, month, day, hour, minute, second, and millisecond using local time or UTC. According to the ECMAScript standard, the Date object should represent any date and time to millisecond precision and within 100 million days before or after 1970.

How to Add 1 Day to Date in JavaScript?

The best way to add 1 day to a JavaScript date is by using the Date object. On an existing Date , you can use the getDate function to get the day (between 1 and 31), add 1 to this number, then use setDate to update the date. Here’s a short example: date.setDate(date.getDate() + 1) .

Using the JavaScript Date Object

In JavaScript, you’ll often manipulate the Date object to do diverse operations (e.g., add days to a date, format a date, etc.).

If you want to add one day to date, you can use a combination of these two Date functions:

In practice, let’s say you have this date: 05/12/2022 . The getDate() function will return 5 . Then you can add one day to this number 5 + 1 = 6 . Finally, use setDate() to update the day of the month for your current date object.

Date.prototype.getDay()

The getDay() method returns the day of the week for the specified date according to local time, where 0 represents Sunday. For the day of the month, see Date.prototype.getDate() .

Return value

An integer number, between 0 and 6, corresponding to the day of the week for the given date, according to local time: 0 for Sunday, 1 for Monday, 2 for Tuesday, and so on.

Using getDay()

The second statement below assigns the value 1 to weekday , based on the value of the Date object xmas95 . December 25, 1995, is a Monday.

Note: If needed, the full name of a day ( "Monday" for example) can be obtained by using Intl.DateTimeFormat with an options parameter. Using this method, the internationalization is made easier:

Add Days to Current Date in JavaScript

This tutorial will introduce how to add a new day to the current date or a custom date in JavaScript. We will first introduce what is Date and different methods in JavaScript Date class.

Understand JavaScript Date Class

When we call the Date() constructor without giving any parameters, the Date object will have the current date and time; while when given a parameter, that object will have the parsed string representing that point of time.

Add Days to Date() in JavaScript

Suppose we want to create a function that adds a certain number of days in JavaScript. In that case, we can implement it using the Date class method named getDate() which returns the day of the month, between 1 and 31, for the selected date according to local time, and the method setDate() to set the day of the month for that specific date.

If we are interested in adding that day to today, we can replace new Date(date) with new Date() in the above code, or we can pass the new Date() to the function directly.

How to Add 1 Day to a Date using JavaScript

Add 1 Day to a Date using JavaScript #

To add 1 day to a date:

The addOneDay function takes a Date object as a parameter and adds 1 day to the date.

If you need to add 1 day to the current date, call the Date() constructor without passing it any arguments.

We used the Date() constructor to create a Date object that represents the current date.

The getDate() method returns an integer between 1 and 31 that represents the day of the month for the date.

The setDate() method takes a number that represents the day of the month as a parameter and sets the value on the Date .

The JavaScript Date object automatically takes care of rolling over the month and/or year if adding a day to the date increments the month and year.

The example shows how creating a date for the 28th of February 2023 and adding 1 day to the result rolls the month over to March.

Add 1 day to a Date without mutation #

Note that the setDate method mutates the Date object it was called on.

If you don't want to change the Date in place, create a copy of it before calling the method.

When a Date object is passed to the Date() constructor, it gets converted to a timestamp and can be used to create a copy of the date.

Mutating function parameters is a bad practice because calling the function with the same parameter multiple times returns different results.

Instead, pure functions like the one above return the same output when called with the same parameters.

Add 1 Day to a Date using date-fns #

You can also use date-fns module to add 1 day to a date.

The addDays() function takes a date and the number of days to be added to the date as parameters.

The function doesn't mutate the original date as shown in the example.

If you don't have date-fns installed, you can install it by running the following command from your terminal.

Add 1 Day to a Date using moment.js #

You can also use the moment.js module to add 1 day to a date.

We used the moment().add() method to add 1 day to a date.

The method can be used to add years, quarters, months, weeks, days, hours, minutes, seconds or milliseconds to a date.

If you don't have moment installed, you can install it by running the following command from your terminal.

The call to the add() method actually returns a moment object and not a native JavaScript date.

If you need to convert the value to a JavaScript date, use the toDate() method.

The toDate() method takes care of converting the moment object to a native JavaScript Date object.

How to Add Days to Date in JavaScript

A Date is a built-in object in JavaScript. To create a new Date object, use the new Date(), a set of methods become available to operate on it. Date objects contain a Number that represents milliseconds since 1 January 1970 UTC.

JavaScript does not have any built-in function that can add days to the date. Then, how to add days to the current Date using JavaScript? Well, you can create a function of your own that can add days to the current date.

Add Days to Date in JavaScript

To add days in date in JavaScript, use the combination of date.setDate() and date.getDate() function. These methods are used to set and get the day of the month of the Date object. JavaScript Date objects represent a single moment in time in the platform-independent format.

Today’s date is 2nd July 2021. If we add 10 days to the current date, you will get 12th July 2021 .

In this example, first, we have created a function that takes days as an argument.

The valueOf() function r eturns the primitive value of a String object. Then we created a new Date object.

Then we set a date from the current date + 10 days. This takes care of automatically incrementing the month if necessary.

You can write the above function in ES6 fashion, which is a very modern approach.

When the new Date() is called a constructor, it returns a new Date object.

That’s it for this tutorial.

Add Days to Current Date in JavaScript

John on June 09, 2021

To add days to a Date() object in JavaScript, use the setDate() function – inside it get the current date using the .getDate() function then add the number of days to increment using the addition operator ( + ).

To demonstrate this, we will first create a basic example of adding five days to a Date() object then create a function to add any number of days to a date dynamically.

Adding Days to a Date

In the example below, five days are added to a Date() object using the current time.

Today's Date Plus N Days in JavaScript

A more robust solution that follows the "don't repeat yourself principles" would be to create a function that we can pass any date and days to add and get the resulting Date() object back.

September 7, 2021

The setDate() and getDate() methods of the Date object can be used to increment or decrement days from a date in JavaScript.

The following example demonstrates how you can add 7 days to the current date:

You can also update the existing JavaScript Date object as shown below:

To subtract days from a date in JavaScript, simply minus the number of days when updating date with the setDate() method:

Finally, if you are frequently manipulating dates in JavaScript, just add a function to Date ’s prototype and call it directly whenever you want to add or subtract days:

JS Tutorial

Js versions, js functions, js html dom, js browser bom, js web apis, js vs jquery, js graphics, js examples, js references, javascript date formats, javascript date input.

There are generally 3 types of JavaScript date input formats:

The ISO format follows a strict standard in JavaScript.

The other formats are not so well defined and might be browser specific.

JavaScript Date Output

Independent of input format, JavaScript will (by default) output dates in full text string format:

JavaScript ISO Dates

ISO 8601 is the international standard for the representation of dates and times.

The ISO 8601 syntax (YYYY-MM-DD) is also the preferred JavaScript date format:

Example (Complete date)

The computed date will be relative to your time zone. Depending on your time zone, the result above will vary between March 24 and March 25.

ISO Dates (Year and Month)

ISO dates can be written without specifying the day (YYYY-MM):

Time zones will vary the result above between February 28 and March 01.

ISO Dates (Only Year)

ISO dates can be written without month and day (YYYY):

Time zones will vary the result above between December 31 2014 and January 01 2015.

ISO Dates (Date-Time)

ISO dates can be written with added hours, minutes, and seconds (YYYY-MM-DDTHH:MM:SSZ):

Date and time is separated with a capital T.

UTC time is defined with a capital letter Z.

If you want to modify the time relative to UTC, remove the Z and add +HH:MM or -HH:MM instead:

UTC (Universal Time Coordinated) is the same as GMT (Greenwich Mean Time).

Omitting T or Z in a date-time string can give different results in different browsers.

When setting a date, without specifying the time zone, JavaScript will use the browser's time zone.

When getting a date, without specifying the time zone, the result is converted to the browser's time zone.

In other words: If a date/time is created in GMT (Greenwich Mean Time), the date/time will be converted to CDT (Central US Daylight Time) if a user browses from central US.

JavaScript Short Dates.

Short dates are written with an "MM/DD/YYYY" syntax like this:

In some browsers, months or days with no leading zeroes may produce an error:

The behavior of "YYYY/MM/DD" is undefined. Some browsers will try to guess the format. Some will return NaN.

The behavior of "DD-MM-YYYY" is also undefined. Some browsers will try to guess the format. Some will return NaN.

JavaScript Long Dates.

Long dates are most often written with a "MMM DD YYYY" syntax like this:

Month and day can be in any order:

And, month can be written in full (January), or abbreviated (Jan):

Commas are ignored. Names are case insensitive:

Date Input - Parsing Dates

If you have a valid date string, you can use the Date.parse() method to convert it to milliseconds.

Date.parse() returns the number of milliseconds between the date and January 1, 1970:

You can then use the number of milliseconds to convert it to a date object:

How to add 1 day to date in JavaScript?

To add 1 day to date, follow the following steps:

JavaScript provides the Date class to represent date and time. You create a Date object by calling the Date() constructor.

The setDate() method sets the day of the month, and it accepts an integer value.

In this example, we created a Date object representing 31st January, and adding 1 day gives 1st February.

Another Date object is created that represents 31st December 2019, and incrementing the date by 1 day gives 1st January 2020.
