Is Google Calender free?

Google calendar comes with a free version and a business version. While anyone with a Google account can access the free version, it does come with limited features that might not be adequate enough for business with advanced needs. For Eg. The free version only allows you to share the calendar in read-only form while the business version lets you add, delete or change events by as many users as possible.

The business version of Google Calendar comes at a price of $5 per month per user or $50 per year per user. Google offers a 30 day free trial to get a better insight of things.
