For my use case though, eliminating Javascript made sense. This tutorial assumes basic knowledge of Django and its development patterns. If you want to try coding along, I have built this minimal boilerplate as a base for quick development. In a traditional Django application, there are two ways users can make a request to the server. After the request is processed, the server returns a new HTML template. HTMX gives us two superpowers. The first superpower is the response of the server doesn't have to replace the whole page.
It can replace just the pieces of the DOM we specify. The second superpower is that we can make a request to the server with anything in the DOM. We can even make a request every second, without the user doing anything polling. This is exactly what we will do for our countdown timer. The first two parts are easy. For HTMX, we just need a couple of lines in our base. In that view, we are using the Python datetime module to calculate the time difference between two days.

The datetime module of Python offers classes for manipulating dates and times easily. You can format any date of Python as long as it is a datetime object using the strftime method.
A datetime object will have the method strftime that allows you to provide a custom format to a date and print it as a string wherever you need to.
You can specify how and where every part of the date should be rendered with the following identifiers:. Within the controller, you have access directly to the datetime object. That means that you can simply execute the strftime function an pass the format string as first argument:. And there are 2 ways to use the datetime module to fetch the current date. The first way is to use the date. Here is an example of using the date. In the example, first, we have imported the datetime module.
After this, we are using date. In the end, we are returning the date as an HTTP response. The second method is by using the datetime class from the datetime module. In this, we have to use the datetime. Here is an example of using datetime. In the example, we have imported the datetime class from the datetime module. Next, we are using the datetime. In the end, we are returning the variable as a response. And this example will also return the same result as shown above.
Read: How to setup Django project. Till now, we were only discussing fetching the current date and time in the views file. Now, we will understand how to get the current date and time in the Django templates.
In Django, there are 2 methods to get the current time in the templates. The first method is to get the current time in the views. And then, use it in the template to get the output. The second method is by using Django template tags to fetch the current time.
In this first method, we will use the views. In the above code, we have created a function-based view with the name index. And in this view, we have defined a variable that will store the value of the current time using datetime.
And then, we have sent the variable to the index. Now to display the current time using the variable, we have to add the following code to the index. In this approach, we will simply create a view that will redirect to an HTML page.
First, the code of the views.
