Django Happenings

Build Status - master branch Coverage Status Pypi Version

An event calendar app for Django.


  • Repeating and non-repeating events
  • Events that start and end on different days
  • Support for cancelled events
  • Upcoming events and current happenings lists
  • AJAX support
  • Default CSS & Javascript to help you get started

Coming soon:

  • better integration of categories and tags
  • more views, including an agenda view
  • support for users
  • ++ more

Note about upgrading from previous versions: Upgrading your version of the app is a good idea, but be aware that some updates to the app involve changes to models, which may cause problems with your database. For this reason I've included south migrations to help make upgrading easier. But you should always be cautious and make sure to backup your database before upgrading. To see a list of changes made for each version view the CHANGELOG.



  • Django 1.6+
  • Python 2.6+, 3+
  • pytz


  • jQuery
  • Twitter Bootstrap 3.0.0+ (w/ tooltip plugin)
  • South (for database migrations)

jQuery is used for AJAX and the 'Today' button on the calendar.

TWBS is used to create popovers when an event is clicked on the calendar.


django-happenings now use Django migrations by default. South users have to adjust their settings:

    'taggit': 'taggit.south_migrations',
    'happenings': 'happenings.south_migrations',

Quick Install

  1. Install with pip:

    $ pip install django-happenings
  2. Add happenings to INSTALLED_APPS:

  3. Include the django-happenings URLconf in urls.py:

    url(r'^calendar/', include('happenings.urls', namespace='calendar'))

    If your are going to use different namespace then please set CALENDAR_URLS_NAMESPACE in settings

  4. Make sure your TIME_ZONE is set correctly in settings.py.

  5. Run python manage.py migrate to create the models (replace migrate with syncdb happenings if using older Django without South). If you're running MySQL, be sure that your database is properly configured to use time zones.

  6. Run the development server and go to to create and manage events.

  7. Check out the calendar at


The quickest way to begin customizing the app is to override the middle.html template by creating your own version in <mytemplates>/happenings/middle.html (replace <mytemplates> with wherever you keep your templates) and add the line {% extends 'base.html' %} (replace base.html with your base template). For a greater degree of customization, you can copy and paste into your project all of the templates included in the app, and change them to fit your needs.

Be sure to include the packaged css & javascript into your base template if you want to use them. Loading the default style into your template would look something like (assuming staticfiles has been loaded):

<link href=" {% static 'happenings/css/calendar.css' %}" rel="stylesheet">

And the default javascript something like:

<script src="{% static 'happenings/js/calendar.js' %}"></script>

Template Tags

Template tags are available by loading happenings_tags into your template:

{% load happenings_tags %}

This gives access to three template tags: show_calendar, upcoming_events, and current_happenings.

Use show_calendar like this:

<div id="event-calendar">
    {% show_calendar request %}

to display a calendar like the one in /calendar/, or like this:

<div id="event-calendar" class="calendar-mini">
    {% show_calendar request mini=True %}

to display a mini calendar. The <div> shown allows you to use the styles included with the app, but you can omit or change them if you want to use your own style. Note also that, because the request object needs to be included in the tag, you must include "django.core.context_processors.request" in TEMPLATE_CONTEXT_PROCESSORS in your settings.py.

If you are using custom templates for calendar and want to access all variables from current template context then you can call show_calendar tag with inherit_context=True argument:

<div id="event-calendar">
{% show_calendar request inherit_context=True %}


Include upcoming_events in your template like this:

{% upcoming_events %}

to display a list of the next 5 (or less) upcoming events within the next 90 days. If you'd like to show events that occur outside of 90 days, or show more events in the list, use the finish and num options:

{% upcoming_events finish=365 num=8 %}

Include current_happenings in your template like this:

{% current_happenings %}

to display a list of events that are happening now.


There are no translations from English yet, but if you'd like to display the calendar and the event list in a different language, you can use CALENDAR_LOCALE. The upcoming events list won't be translated, though. For that you'll need to specify your LANGUAGE_CODE in the Django settings. Also note that to use CALENDAR_LOCALE you'll need to have the correct locale pack installed for your system. Example of changing the language to German:


Example of changing to U.S. English:


By default, the system's locale is used, so setting CALENDAR_LOCALE also ensures that you're using the locale you want.

Optional Settings

You can specify different settings for the app in your settings.py file.

Use CALENDAR_URLS_NAMESPACE if you included happenings.urls with namespace other than 'calendar'

Use CALENDAR_COLORS to add a custom color to the drop down in the admin when creating an event. Example of setting the custom color 'fuchsia':

CALENDAR_COLORS = [('ff00ff', 'fuchsia')]

Use CALENDAR_START_DAY to change the day on which the calendar starts. Example of starting the calendar on Sunday (instead of the default of Monday):


Default time format is "TIME_FORMAT" (user locale dependend if USE_L10N is used or default django format if not used). This can be changed with next setting:

## or
# CALENDAR_HOUR_FORMAT = 'g:iA'  # 12 hour format with AM/PM

In titles of events minutes may be stripped from time when there are 0 minutes. This depends on i18 settings and your CALENDAR_TIME_FORMAT settings. You may set some specific value with next setting:

## or
# CALENDAR_HOUR_FORMAT = 'gA'  # 12 hour format with AM/PM

## or if you do not want minutes to be stripped

Upgrading from 0.2.X to 0.3.X

Starting from 0.3.1 calendar rendering uses django templates to generate calendar cells (templates/happenings/partials/calendar/*.html`). If you haven't customized anything and used default settings then everything will still work out of the box.

If you have sublcassed EventCalendar or MiniEventCalendar calendar then you have 2 options:

  • subclass LegacyEventCalendar or LegacyMiniEventCalendar. You should also set CALENDAR_LEGACY_TIME_FORMAT in settings.
  • copy templates/happenings/partials/calendar/*.html` templates to your project templates directory and customize them

If you are using custom CALENDAR_TIME_FORMAT setting then you also have 2 options:

  • Just remove this setting and use default setting of django TIME_FORMAT.

  • change it from python strftime notation to Django (PHP) notation. Specifying CALENDAR_HOUR_FORMAT is also a good idea:

    # CALENDAR_TIME_FORMAT = '%H:%M'  # pre 0.3.1 version

If you used event.l_start_date()/event.l_end_date()/event.start_end_diff() in your code:

  • They are now cached_properties: use them without brackets or use get_FOO() (example: get_l_start_date())

Event details template (tempaltes/happenings/event_detail.html) now uses "SHORT_DATE_FORMAT" instead of "D F d, Y" format. To use old format either change SHORT_DATE_FORMAT in settings or copy templates and change them as you like.

Url to day details view (EventDayView) is now build using reverse. This may have broken rendering for projects which included happenings.urls in their urlconf with namespace other than "calendar". In such case you have to set CALENDAR_URLS_NAMESPACE in settings to namespace that you use (empty string is allowed for those who do not use namespace).

Starting from 0.3.3 django happenings does not use locale.setlocale and fully utilizes i18n features if django. To set default calendar language you should set LANGUAGE_CODE in settings. If you have enabled language switching for your site then calendar will switch languages too. If you are not using legacy calendars then CALENDAR_LOCALE settings is not required anymore.

Note that only month names and weekday names are translated for all languages supported by django. Some django-happenings specific strings are only available in English (like "When/Description" in event details). You can generate your own translations (pull requests are welcome) or you may copy and change templates.


Tox is used for testing.

$ pip install tox

$ tox -e py27-django16
