The JavaScript Date setDate() Method is used to set the date of a month into a date object which is created using the date() constructor.
Syntax:
dateObj.setDate(date_Value);
Parameter: This method accepts a single parameter as mentioned above and described below:
- date_Value: It returns the new i.e updated date of the month which is set by the setDate() method. The date of the month is an integer value ranging from 1 to 31.
Return value: This method return the number of milliseconds between the date object and midnight of January 1, 1970
Note: DateObj is a valid Date object created using Date() constructor in which we want to set the date of a month.
Below is an example of the Date setDate() method.
Example 1:
javascript
// Here a date has been assigned // while creating Date object let dateobj = new Date( 'October 13, 1996 05:35:32' ); // new date 15 of the month is being set // in above Date Object with the help of // setDate() method dateobj.setDate(15); // new date of the month from above Date // Object is being extracted using getDate() let B = dateobj.getDate(); // Printing new date of the month console.log(B); |
Output:
15
More codes for the above method are as follows:
Example 2: Here as we know the date of the month, lies between 1 to 31 but if we suppose to set the date as 33, it will set date 2 for the next month because, and this date 2 becomes the date for the next of the previous month. In the below output, 2 is the date of November month and 10 is the month of November because the month name starts from 0 to 11 i.e, 0 for January and 11 for December.
javascript
// Here a date has been assigned // while creating Date object let dateobj = new Date( 'October 13, 1996 05:35:32' ); // New date 33 of the month is being set // in above Date Object with the help of // setDate() method dateobj.setDate(33); // new date of the month from above Date // Object is being extracted using getDate() let B = dateobj.getDate(); // new month from above Date Object is // being extracted using getMonth() let C = dateobj.getMonth(); // Printing new date of the month console.log(B); // Printing new month console.log(C); |
Output:
2 10
Example 3: If in the Date() constructor we do not give any date of the month, still setDate() method set a new date which is given as its parameter.
javascript
// Here date has not been assigned // while creating Date object let dateobj = new Date( 'October, 1996 05:35:32' ); // New date 12 of the month is being set // in above Date Object with the help of // setDate() method dateobj.setDate(12); // new date of the month from above Date // Object is being extracted using getDate() let B = dateobj.getDate(); // Printing new date of the month console.log(B); |
Output:
12
Example 4: If nothing as a parameter is given in the Date() constructor, still the setDate() method sets the date but the month becomes the current month.
javascript
// Here a date has been assigned // while creating Date object let dateobj = new Date(); // New date 13 of the month is being set // in above Date Object with the help of // setDate() method dateobj.setDate(13); // Date of the month from above Date Object // is being extracted using getDate() let B = dateobj.getDate(); // Month from above Date Object is // being extracted using getMonth() let C = dateobj.getMonth(); // Printing new date of the month console.log(B); // Printing new month console.log(C); |
Output:
13 10 //current month
Example 5: If the new date of the month is set to zero (0), the new date will be set to the last day of the previous month.
javascript
// Here a date has been assigned // while creating Date object let dateobj = new Date( 'October 13, 1996 05:35:32' ); // new date 0 of the month is being set // in above Date Object with the help of // setDate() method dateobj.setDate(0); // Date of the month from above Date Object // is being extracted using getDate() let B = dateobj.getDate(); // Month from above Date Object is // being extracted using getMonth() let C = dateobj.getMonth(); // Printing new date of the month console.log(B); // Printing new month console.log(C); |
Output:
30 8
