No I don' t share my own calendar, but I have created another calendar. I cut and paste from Google website :
You can create a new calendar and invite other people to view or edit it. When you create an event, you'll see an option to choose which calendar to add the event to.
- On your computer, open Google Calendar. You can't create or share calendars from the Google Calendar app.
- On the left, next to "My Calendars," click the Down arrow .
- Click Create a new calendar.
- Add the calendar name.
- Under "Share with specific people," add the email address of the person you want to share with.
- Under "Permission Settings," choose an option in the drop-down menu. Learn more about these options below.
- If someone isn't already added, click Add person.
- Click Create calendar.
If you shared your calendar with an individual email address, they'll see your calendar in their "Other calendar" list. If you shared your calendar with an email group , they'll see the calendar in their "Other calendars" list once they click on the link in the email invitation from Google Calendar.
Important: To get your new calendar to show up on your Android phone or tablet, you'll need to
turn on sync for that calendar.
