Gmail – How to make the calendar in corporate Google account visible to someone outside? (But only availability)

So you can grab the embed code from the html link in the share settings and splice them together manually. I needed this and just now experimented and it works. There are four parts to a public calendar link.

So they are all like this

1. "https://google.com/calendar/"
2. embed type + "?"
3. "src=" + unique string/name
4. "&ctz=" + timezone string (optional)

And it turns out you can add "&src=UNIQUESTRING" an often as you like. So making sure that either your calendars are wide open, showing free/busy or you are sharing with someone who has been given permission to the calendar in your share settings.

The title for the page is pulled from the first calendar in your src string. And all the colors are the same so you can't tell which calendar is which.

Embed

determines the embed type.

htmlembed embed src= a unique string like this one for NCAA UK basketball schedule

src=ncaab_292_%254bentucky%2B%2557ildcats%23sports%40group.v.calendar.google.com

&ctz= I assume it is for current time zone. Sets your timezone offset

&ctz=America/New_York

So here is a link to a combination of UofK basketball,Jewish Holidays, a home maintenance calendar and a local hackerspace in my hometown.

I have had limited success with the following format:

Subject: My test event

Email body says:

This is my test event!

When: May 7, 9-10AM
Where: 123 Main Street, Berkeley, CA

Using the keyword "Location" instead of "Where" seems to work also.

In Google Calendar, this will populate the Subject, the body and the event time and the event location (The field labeled "Where").

I have been using the above format with my personal Gmail account, and my institution's Google Apps account. It usually works with the "Add to Calendar" button, and with the "More: Create event" menu option.
