Var d2 = new Date(d1.getFullYear(), d1.getMonth(), d1.getDate() + 14) īoth of those work even when you're going past the end of the month, btw.Ĭomplete example of the second option: Live Copy ĭ2 = new Date(d1.getFullYear(), d1.getMonth(), d1.getDate() + 14) ĭ(document.createElement('hr')) ĭ2 = new Date(d1.getFullYear(), d1.getMonth(), d1. Parameter: This method accept a single parameter as mentioned above and described below: dateValue: It returns the new i.e updated date of the month which is set by setDate () method. That gives us August 1st for d1, and August 15th for d2.Īnother option is: var d1 = new Date(2014, 7, 1) The tDate () method is used to set date of a month into a date object which are created using date () constructor. Var d2 = new Date(d1) // Clone that dateĭ2.setDate(d1.getDate() + 14) // Move forward 14 days for this line: startdate28 tDate (startdate.getDate ()+28) You store what returns from 'tDate' inside 'startdate28' and this function return the time stamp for the adjusted date. The syntax of the JavaScript setDate function is: tDate (DayNumber) JavaScript setDate Function Example Here, we used the setDate function to set the current day to 25th. You probably want: var d1 = new Date(2014, 7, 1) // A specific date JavaScript setDate function is one of the Date Function, which is used to set the Day number of a given date as per local time. Since you've initialized d2 with today, you're just changing the day-of-month for that date, not taking on any other aspect of d1. If you set the date using this function to zero then the date will be set to the last day of the previous month.SetDate, somewhat surprisingly, sets the day-of-the-month of the existing instance. In the same way, though you do not pass any value to the constructor while creating the date object still you can set the Date using this function and the month and year value remain same as the current date. The problem here is that JavaScript is a dynamically typed language, and is therefore not the same as typed languages like PHP or Python. Javascript is a subset of a programming language called ECMAScript, which is a superset of the programming language JavaScript. Though you do not mention the date of the month while creating the date object, You can still set it using the setDate() function. for this line: startdate28 tDate (startdate.getDate ()+28) You store what returns from 'tDate' inside 'startdate28' and this function return the time stamp for the adjusted date. The last time setDate() was used was in 2009, so we’re in the 21st century. Var dateObj = new Date('september 26, 89 12:4:25:96') ĭocument.write("Current date: "+dateObj.toUTCString()) ĭocument.write("Date after modification: "+dateObj.toUTCString()) ĭate after modification: Fri, 06:34:25 GMTMT Example These methods allow getting and setting the year, month, day, hour, minute, second, and millisecond using either local time or UTC time. Once a Date object is created with the New Date (), a set of methods become available to operate on it. ![]() Its Syntax is as follows tDate(5) Example The Date is a built-in object in JavaScript. JavaScript dateObj </ var >.setDate(dayValue </ var >) Parameters dayValue An integer representing the day of the month.The setDate() function of the date object accepts an integer representing the day of the month and modifies/replaces the current date with it. () The setDate() method sets the day of the Date object relative to the beginning of the currently set month. Most methods simply allow you to get and set the year, month, day, hour, minute, second, and millisecond fields of the object, using either local time or UTC (universal, or GMT) time. Once a Date object is created, a number of methods allow you to operate on it. ![]() Date objects are created with the new Date() constructor. Date objects are created with the new Date( ) as shown below. By default, JavaScript will use the browsers time zone and display a date as a full text string: You will learn much more about how to display dates, later in this tutorial. The Date object is a data type built into the JavaScript language. Se o dayValue estiver fora da extensão de valores de data para o mês, setDate () vai atualizar o objeto Date consequentemente. The JavaScript date setDate() method sets the date value for the particular date on the basis of local time.
