Welcome to the community, @Krista_Grenstromer!
Are you on a Pro Plan? Only Pro Plans allow start times & end times.
However, even if you’re already on the Pro Plan, unfortunately both the start time & the end time are only visible on the Day, Week, and 3-Day views of the calendar.
They are not visible on the Month and 2-Week views.
As a workaround, you could share your calendar to an external calendar client like BusyCal for syncing and view your events there. (However, Airtable only shares 3 pieces of information with external calendar clients: start time, end time, and the primary field value).
