Display Only the Date Part of a DateTimeField in a Django Template

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

Hello everybody.

I'm using a Django model where one of the fields is a DateTimeField called finished_date. I only want to render the date portion in my template, but when I use {{ book.finished_date }} it displays the full date-time string. I've considered extracting the date with datetime.date() in the view and passing it separately, but I suspect there's a simpler solution—maybe even by overriding the field's string representation in the model. Any suggestions would be appreciated.

The model:

PYTHON
class Book(models.Model):
    
    title = models.CharField(max_length=75)
    author = models.CharField(max_length=75)
    book_owner = models.ForeignKey(get_user_model(), on_delete=models.CASCADE, related_name="books")
    order = models.PositiveSmallIntegerField()
    cover = models.ImageField(upload_to="covers/", blank=True, null=True)
    
    # these are new
    finished = models.BooleanField(default=False)
    finished_date = models.DateTimeField(blank=True, null=True)
    review = models.TextField(blank=True, null=True)
    
    class Meta:
        ordering = ['order']
    
    def __str__(self):
        return self.title

The template:

HTML
<div class="p-2" style="width: 95%; margin: auto;">
    <h1 class="my-4 text-start">My completed books</h1>
    <p class="lead">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>
    <table class="table">
        <thead>
        <tr>
            <th scope="col">Title</th>
            <th scope="col">Author</th>
            <th scope="col">Review</th>
            <th scope="col">Date Finished</th>
        </tr>
        </thead>
        <tbody>
        {% for book in finished_book_list %}
        <tr>
            <td>{{book.title}}</td>
            <td>{{book.author}}</td>
            <td>{{book.review}}</td>
            <td>{{book.finished_date}}</td>
        </tr>
        {% endfor %}
        </tbody>
    </table>
</div>

What is the simplest way to modify my template or model so that only the date (and not the time) is displayed?

Using the Date Filter in Django Templates

The simplest way to display only the date portion of your finished_date DateTimeField is to use Django's built-in date template filter. This filter allows you to format datetime objects according to your needs without modifying your model.

Solution

Modify your template to use the date filter like this:

HTML
<td>{{ book.finished_date|date:"Y-m-d" }}</td>

You can customize the date format to your preference. For example:

HTML
<!-- Standard date format (e.g., "Jan. 9, 2023") -->
<td>{{ book.finished_date|date }}</td>

<!-- Short date format (e.g., "01/09/2023") -->
<td>{{ book.finished_date|date:"SHORT_DATE_FORMAT" }}</td>

<!-- Custom format (e.g., "Monday, January 9, 2023") -->
<td>{{ book.finished_date|date:"l, F j, Y" }}</td>

Format Options

Django's date filter supports various format characters:

Y: Four-digit year (e.g., 2023)
m: Month as a zero-padded decimal (e.g., 01, 12)
d: Day of the month as a zero-padded decimal (e.g., 01, 31)
F: Month name in full (e.g., January)
j: Day of the month without leading zeros (e.g., 1, 31)

You can also use predefined formats like DATE_FORMAT or SHORT_DATE_FORMAT, which will respect the current locale settings in your Django project.

This approach is preferable to modifying your model since it keeps the full datetime information in the database while only changing how it's displayed in the template.
