help find a common calendar to work with freelancers, not google docs

Question

Freelance

Need a shared calendar for a freelance company. Each freelancer under his account should have a simple calendar in which he can mark the days free to receive an order. And this data from all freelancers should be automatically visible to the administrator in his calendar. Ideally, export to Excel is also needed ... Is there such a service?

google docs is not suitable - not everyone has gmail
