A Python library to merge iCalendar feeds.

Merging two calendars might look easy but it is not! Here is a list of features:

  • ✅ Google Calendar Compatibility (X-WR-TIMEZONE)
  • ✅ Add Timezones in the right place
  • ✅ handle duplicated events
  • ✅ handle modifications (deletion, addition) of events

Installation

Install this via pip (or your favorite package manager):

pip install mergecal

Usage

Python API

You can use MergeCal in your Python code as follows:

>>> from mergecal import merge_calendars
>>> from icalendar import Calendar

# Load your calendars
# CALENDARS = pathlib.Path("to/your/calendar/directory")
>>> calendar1 = Calendar.from_ical((CALENDARS / "one_event.ics").read_bytes())
>>> calendar2 = Calendar.from_ical((CALENDARS / "another_event.ics").read_bytes())

# Merge the calendars
>>> merged_calendar : Calendar = merge_calendars([calendar1, calendar2])

# Write the merged calendar to a file
>>> (CALENDARS / "merged_calendar.ics").write_bytes(merged_calendar.to_ical())
933

# The merged calendar will contain all the events of both calendars
>>> [str(event["SUMMARY"]) for event in calendar1.walk("VEVENT")]
['Event 1']
>>> [str(event["SUMMARY"]) for event in calendar2.walk("VEVENT")]
['Event 2']
>>> [str(event["SUMMARY"]) for event in merged_calendar.walk("VEVENT")]
['Event 1', 'Event 2']

Command Line Interface (CLI)

MergeCal also provides a command-line interface for easy merging of calendar files:

# Basic usage
mergecal calendar1.ics calendar2.ics -o merged_calendar.ics

# Specifying custom PRODID
mergecal calendar1.ics calendar2.ics -o merged_calendar.ics --prodid "-//My Organization//MergeCal 1.0//EN"

For more options and information, use the help command:

mergecal --help
