Can I get all my calendars to view on icloud desktop?

On my iphone and Ipad, I have all my sorted calendars viewing in the calendar app.

When I'm in my office using Icloud calendar, of course I only view the one calendar.

I know others have asked similar questions, and commenting on those threads seem to be off.

Is there any option for viewing all my calendars together on windows desktop like my Iphone does?
