Link to add to Google calendar

I am unclear about the exact format to have a link on a website that will add a single event to a users Google calendar. I see that eventbrite has done it here but I would love some clear specs or links in the right direction

Solution 1:

Here's an example link you can use to see the format:

https://www.google.com/calendar/render?action=TEMPLATE&text=Your+Event+Name&dates=20140127T224000Z/20140320T221500Z&details=For+details,+link+here:+http://www.example.com&location=Waldorf+Astoria,+301+Park+Ave+,+New+York,+NY+10022&sf=true&output=xml

Note the key query parameters:

text
dates
details
location

Here's another example (taken from http://wordpress.org/support/topic/direct-link-to-add-specific-google-calendar-event):

<a href="http://www.google.com/calendar/render?
action=TEMPLATE
&text=[event-title]
&dates=[start-custom format='Ymd\\THi00\\Z']/[end-custom format='Ymd\\THi00\\Z']
&details=[description]
&location=[location]
&trp=false
&sprop=
&sprop=name:"
target="_blank" rel="nofollow">Add to my calendar</a>

Here's a form which will help you construct such a link if you want (mentioned in earlier answers):

Solution 2:

There is a comprehensive doc for google calendar and other calendar services: https://github.com/InteractionDesignFoundation/add-event-to-calendar-docs/blob/master/services/google.md

An example of working link: https://calendar.google.com/calendar/render?action=TEMPLATE&text=Bithday&dates=20201231T193000Z/20201231T223000Z&details=With%20clowns%20and%20stuff&location=North%20Pole

Solution 3:

I've also been successful with this URL structure:

Base URL:

https://calendar.google.com/calendar/r/eventedit?

And let's say this is my event details:

Title: Event Title
Description: Example of some description. See more at https://stackoverflow.com/questions/10488831/link-to-add-to-google-calendar
Location: 123 Some Place
Date: February 22, 2020
Start Time: 10:00am
End Time: 11:30am
Timezone: America/New York (GMT -5)

I'd convert my details into these parameters (URL encoded):

text=Event%20Title
details=Example%20of%20some%20description.%20See%20more%20at%20https%3A%2F%2Fstackoverflow.com%2Fquestions%2F10488831%2Flink-to-add-to-google-calendar
location=123%20Some%20Place%2C%20City
dates=20200222T100000/20200222T113000
ctz=America%2FNew_York

Example link:

https://calendar.google.com/calendar/r/eventedit?text=Event%20Title&details=Example%20of%20some%20description.%20See%20more%20at%20https%3A%2F%2Fstackoverflow.com%2Fquestions%2F10488831%2Flink-to-add-to-google-calendar&location=123%20Some%20Place%2C%20City&dates=20200222T100000/20200222T113000&ctz=America%2FNew_York

Please note that since I've specified a timezone with the "ctz" parameter, I used the local times for the start and end dates. Alternatively, you can use UTC dates and exclude the timezone parameter, like this:

dates=20200222T150000Z/20200222T163000Z

Example link:

https://calendar.google.com/calendar/r/eventedit?text=Event%20Title&details=Example%20of%20some%20description.%20See%20more%20at%20https%3A%2F%2Fstackoverflow.com%2Fquestions%2F10488831%2Flink-to-add-to-google-calendar&location=123%20Some%20Place%2C%20City&dates=20200222T150000Z/20200222T163000Z

For the next person Googling this topic, I've written a small NPM package to make it simple to generate Google Calendar URLs. It includes TypeScript type definitions, for those who need that. Hope it helps!
