In this example, we used the setDate() and the getDate() methods of JavaScript for subtracting the 12 days from the current day.
#JAVASCRIPT DATE MINUS MINUTES CODE#
The below code example will illustrate the practical implementation of the setDate() and getDate() methods to subtract the day from the date − Ĭlick the below button to subtract 12 days to the Today's Date The change you have to make is, to replace the setTime() and the getTime() methods in the previous example with the setDate() and the getDate() methods respectively. NOTE − The algorithm of this and the previous example are almost similar there is a minor change in the algorithms. Let us understand it with help of a code example − The following syntax can be used to implement the setDate() and getDate() methods in JavaScript − tDate(numberOfDay) It does not accept any type of parameter. GetDate() − The getDate() method simply returns the day of the month that also ranges from 1 to 31, like the getTime() method. On the other hand, it also returns a number between 1 and 31 that denotes the day of the month. It accepts the day as a parameter and sets the day of the date object to the same day passed inside the brackets of this method. SetDate() − The setDate() method sets the day of the month to the date object in JavaScript. Using setDate() and getDate() Methodsīefore going to the implementation let us understand what functions the setDate() and the getDate() methods perform − In this example, we are subtracting 10 days from the current day or the date. You will get all the details about the day you subtracted from the current date just by clicking the button. In the above example, we have used the setTime() and the getTime() methods of JavaScript to subtract day from the date. Result2.innerHTML += "The day we get after subtracting is: " + date
Result1.innerHTML = "Today's Date: " + date + "" Var result2 = document.getElementById("result2") Var result1 = document.getElementById("result1") The below example will explain the practical use of the setTime() and the getTime() methods to subtract the date in JavaScript − Ĭlick below button to subtract 10 days to the Today's Date Step 3 − In the last step, we will write the body of the callback function that contains the logic of subtraction of the date using the setTime() and getTime() methods also the resulting date displaying logic. Step 2 − In next step, first we display the current date to the user on-screen and then define a callback function for the onclick event of the button. Step 1 − In the first step of the algorithm, we need to declare a JavaScript Date object using the JavaScript Date class. Let us understand them practically by implementing them using program examples. The following syntax will be followed to use the setTime() and the getTime() method of the date object − tTime(milliseconds) It does not accept any kind of variable or parameter. GetTime() − The getTime() method returns a number that specifies the number of milliseconds from midnight till the day we are subtracting or adding. This method accepts a parameter in the form of milliseconds that are further added or subtracted from and it also returns the value in the form of milliseconds from till the day or date of the object. SetTime() − The setTime() method sets the date and time in milliseconds by subtracting or adding it from midnight Jan 1, 1970. Let us discuss both of these date methods in details − The setTime() and getTime() methods are used for different purposes. Let us discuss both of them one by one in details. Using the setDate() and getDate() methods Using the setTime() and getTime() methods JavaScript date setDate() method sets the day of the month for a specified date according to local time.įollowing are the methods we can use to subtract days from a date in JavaScript − Under that, get the current days and subtract days. To subtract days from a JavaScript Date object, use the setDate() method.
