How to Add Days to a Date in JavaScript

Adding days to a date in JavaScript is a common task when working with dates. In this blog post, I will show you how to easily add days to a date using the setDate() and getDate() methods.

First, let’s create a new Date object that represents today’s date:

1	const my_date = new Date();

Now, let’s say we want to get the date that is 30 days from now. We can achieve this by adding 30 to the current date using the setDate() method:

1	my_date.setDate(my_date.getDate() + 30);

By calling my_date.getDate(), we get the current day of the month, and then we add 30 to it. This updates the date object to represent the date that is 30 days from now.

Adding days to a date can be useful in various scenarios. For example, if you need to calculate a future deadline or schedule an event in the future, this technique can come in handy.

Remember to adjust the number of days you want to add according to your specific needs. You can also subtract days from a date by using a negative number.
