How to share Family calendar with non-family member?

I have set up our family with iCloud, using iCloud Family Sharing. Currently, myself and my husband define our Family and use our Family calendar for household events.

I also have a work iCloud account and would like to be able to subscribe to my home Family calendar from my work account so that I can see family events on my work calendar. Is this possible, and if so, how can it be done (without adding my work account as a family member)?
