ONE calendar for parents to see the year at a glance

Would like to see a calendar that has the entire year at a glance on ONE calendar - without having to create separate events. So fee due dates, holidays, competition dates, recital that can be seen in one place and could be shared to their own calendars on their phones. I tried to imbed the google calendar but the parameters from google do not allow these details to be seen - only that we are "busy"
