Pull dates from spreadsheet to populate calendar

Hello, I am tracking patients from a pre to post procedure stand point. I have a spreadsheet with columns for medical tests and list the date that they are scheduled to be completed. I would like to be able to automatically pull these dates from the spreadsheet to form a calendar view. These columns and dates change frequently so I'm not sure if this is an option to be able to populate a calendar that is current when I update the dates on the spreadsheet. Thank you
