Original repository (GitHub) - Bugtracker and issues (GitHub) - PyPi package (ics) - Documentation (Read The Docs). Coverage Apache 2 License is a pythonic and easy iCalendar library. It's goals are to read and write ics data in a developer friendly way.

$ pip install ics
from ics import Calendar, Event
c = Calendar()
e = Event() = "My cool event"
e.begin = '20140101 00:00:00'
# [<Event 'My cool event' begin:2014-01-01 00:00:00 end:2014-01-01 00:00:01>]
with open('my.ics', 'w') as my_file:
