Sharing multiple calendars

[Georgina Handyside]

Is there a way to publicly share multiple (not individually) calendars with someone?

I'm in a long-distance relationship, and would like to be able to share my calendar with my partner. My calenders are catagorised (work, school, appointments, etc), and I'd like to be able to share all of the calendars that are relevant to him (ie. not my To-Do calendar) without sending him links to each single calendar.
Is there a way to do this, or am I stuck to taking screenshots of my calendar to send to him?

We use iCloud and I turn off the few calendars of my wife's I don't want to see.
