Create Your Own

To generate these URLs yourself, you can use the following Python function:

import datetime
import sys

from collections import OrderedDict
from typing import Optional

if sys.version_info < (3,):
    from urllib import quote
else:
    from urllib.parse import quote


def generate_google_calendar_event_url(
    title,  # type: str
    start_datetime,  # type: datetime.datetime
    end_datetime,  # type: datetime.datetime
    description=None,  # type: Optional[str]
    location=None,  # type: Optional[str]
    iana_timezone_name=None  # type: Optional[str]
):
    base_url = "https://calendar.google.com/calendar/render"

    query_string_fragments = [
        'action=TEMPLATE',
        'text=%s' % quote(title),
        'dates=%s/%s' % (start_datetime.strftime('%Y%m%dT%H%M%S'), end_datetime.strftime('%Y%m%dT%H%M%S'))
    ]

    if description is not None:
        query_string_fragments.append('details=%s' % quote(description))
    
    if location is not None:
        query_string_fragments.append('location=%s' % quote(location))
    
    if iana_timezone_name is not None:
        query_string_fragments.append('ctz=%s' % quote(iana_timezone_name))
    
    query_string = '&'.join(query_string_fragments)

    return '%s?%s' % (base_url, query_string)

Example

Suppose you want an event: - Title: Sample Event - Date/Time: June 10, 2024, 2pm to 3:30pm - Description: Don't miss this important meeting! - Location: 123 Main St, New York, NY - Time zone: America/New_York

Here's how you'd create the URL:

from zoneinfo import ZoneInfo


generate_google_calendar_event_url(
    title='Sample Event',
    start_datetime=datetime.datetime(2024, 6, 10, 14, 00),
    end_datetime=datetime.datetime(2024, 6, 10, 15, 30),
    description="Don't miss this important meeting!",
    location='123 Main St, New York, NY',
    iana_timezone_name='America/New_York'
)
