How can I invite friends to subscribe to my calendars?

Zoho Calendar enables you to invite friends via email to subscribe your calendars. Go to Settings > My calendar > Sharing and permissions >  "Mail to" option.  All you need to do is type the email addresses of your friends you wish to share the calendar with and click Send. An email invitation will be sent to them along with the unique subscription URL.
