Link to add to Google calendar

Question

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

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):
