Installing OCA Calendar add-ons follows the standard Odoo community module installation process. You retrieve the source from GitHub or PyPI, make the modules visible to Odoo by placing them on the addons path, then activate them through the Apps menu. All six modules in the collection follow the same procedure — only the Python dependencies differ per module, as detailed in the sections below.

​
Installation Steps

1

Get the source code

Choose the method that best fits your deployment.Option A — Clone from GitHub (recommended for development and self-hosted installs):
git clone https://github.com/OCA/calendar -b 18.0
This clones the full repository at the 18.0 branch into a local calendar/ directory containing all six modules.Option B — Install individual modules via pip (recommended for containerised/production installs):
# Install a specific module
pip install "odoo-addon-calendar_event_type_color==18.0.*"
pip install "odoo-addon-calendar_event_description_layout==18.0.*"
pip install "odoo-addon-calendar_export_ics==18.0.*"
pip install "odoo-addon-calendar_import_ics==18.0.*"
pip install "odoo-addon-calendar_public_holiday==18.0.*"
pip install "odoo-addon-resource_booking==18.0.*"

# Or install the full OCA Calendar meta-package (all six modules at once)
pip install "odoo-addons-oca-calendar==18.0.*"
2

Add the modules to Odoo's addons path

If you cloned from GitHub, tell Odoo where to find the modules by adding the cloned directory to your addons_path setting.In your odoo.conf:
[options]
addons_path = /path/to/odoo/addons,/path/to/calendar
If you installed via pip, the modules are placed automatically into your Python environment’s site-packages and Odoo will discover them without any addons_path changes.

Update the module list

Before Odoo can install a newly added module, you must refresh its internal module registry:
  1. Log in to Odoo as an administrator.
  2. Go to Settings and activate Developer Mode (Settings → General Settings → scroll to Developer Tools → Activate the developer mode).
  3. Navigate to Apps in the top menu.
  4. Click Update Apps List and confirm the dialog.
4

Install the module via the Apps menu

  1. In the Apps menu, remove the default “Apps” filter from the search bar so that modules are visible.
  2. Search for the module by name — for example, Calendar Event Type Color or Resource Booking.
  3. Click the Install button on the module card.
  4. Odoo will install the module and any missing Odoo core dependencies automatically.

​
Python Dependencies

Some modules require third-party Python packages that must be present in your Odoo environment before installation:
ModulePython packagePurpose
calendar_public_holidayopenupgradelibHandles data migration during module upgrades
resource_bookingcssselectUsed internally by the booking engine (implicit dependency)
Install any missing packages into the same Python environment that runs Odoo: 
pip install openupgradelib cssselect

​
Module Dependencies (Odoo Core)

Each add-on declares its Odoo module dependencies in __manifest__.py. The table below summarises the required Odoo (and OCA) modules:
ModuleOdoo / OCA dependencies
calendar_event_type_colorcalendar
calendar_event_description_layoutcalendar
calendar_export_icscalendar
calendar_import_icscalendar
calendar_public_holidaycalendar
resource_bookingcalendar, mail, portal, resource, web_calendar_slot_duration
Resource Booking depends on the web_calendar_slot_duration module from the OCA Web repository. This module is not part of Odoo core and must be installed separately before or alongside resource_booking. Follow the same installation process described above for the OCA Web repository, targeting the 18.0 branch.
