Not sure about calendar, but I imagine there's a "sharing" function in the app (i.e. texting or whatever your friends) that would require access to your contacts.
On iOS, it would only ask for this permission when you actually went to share something. With Android, you get asked up front for all these permissions without even knowing why.
