Add calendar event using python caldav

When working with Python, there are often multiple ways to solve a problem. In this article, we will explore different approaches to adding a calendar event using the Python caldav library. We will divide the solution into different sections, each with its own

heading, and include sample code along the way.

import caldav
from caldav.elements import dav, cdav

# Your code here

Option 1: Using the caldav library

The caldav library provides a convenient way to interact with CalDAV servers. To add a calendar event, we can follow these steps:

  1. Connect to the CalDAV server using the caldav.DAVClient class.
  2. Find the calendar we want to add the event to using the caldav.Calendar class.
  3. Create a new event using the caldav.Event class.
  4. Set the necessary properties of the event, such as the summary, start time, and end time.
  5. Save the event to the calendar using the save() method.

Here is an example implementation:

client = caldav.DAVClient(url='')
principal = client.principal()
calendars = principal.calendars()

# Find the calendar
calendar = None
for c in calendars:
    if == 'My Calendar':
        calendar = c

# Create a new event
event = calendar.add_event()
event.add_start('2022-01-01 10:00:00')
event.add_end('2022-01-01 11:00:00')

# Save the event

Option 2: Using the requests library

If you prefer a more low-level approach, you can use the requests library to make HTTP requests directly to the CalDAV server. This gives you more control over the request and response handling. Here is an example implementation:

import requests

url = ''
headers = {'Content-Type': 'text/calendar'}

# Create the calendar event in iCalendar format
event_data = '''
PRODID:-//Example Corp//CalDAV Client//EN

# Send the request to add the event
response = requests.put(url, headers=headers, data=event_data)

# Check the response status code
if response.status_code == 201:
    print('Event added successfully')
    print('Failed to add event')

Option 3: Using a CalDAV client library

If you prefer a more comprehensive solution, you can use a CalDAV client library that provides higher-level abstractions for working with CalDAV servers. One such library is vdirsyncer, which supports synchronization between local files and CalDAV servers. Here is an example implementation:

import vdirsyncer

# Configure the CalDAV server
config = '''
status_path = "~/.vdirsyncer/status/"
collections = ["my_calendar"]

[pair my_pair]
a = "my_local_calendar"
b = "my_remote_calendar"
collections = ["my_calendar"]

# Create the event in the local calendar
with vdirsyncer.Storage(config) as storage:
    event = storage.get_collection('my_local_calendar').add_event()
    event.summary = 'Meeting'
    event.start = '2022-01-01 10:00:00'
    event.end = '2022-01-01 11:00:00'

# Synchronize the local and remote calendars

print('Event added successfully')

After exploring these different options, it is clear that the first option, using the caldav library, provides the most straightforward and convenient solution. It abstracts away the complexities of the CalDAV protocol and provides a simple API for adding calendar events. Therefore, option 1 is the recommended approach for adding calendar events using Python caldav.

    1. Option 2 may seem easier, but its not always about convenience. The requests library may be flexible, but it also adds unnecessary complexity. Sometimes, a simpler solution is the best one. So, lets not dismiss option 1 too quickly.

  1. Option 1: Using the caldav library seems like the most straightforward and efficient way to add calendar events with Python.

  2. I personally prefer Option 1: Using the caldav library because it offers a specific and dedicated solution for adding calendar events in Python.

  3. Option 1: Using the caldav library seems like the most straightforward and efficient way to add calendar events using Python.
