When do clan leagues start?

I can't find info on the site about clan league start dates? How do we find out?

There is not specific date or protocol to start leagues. When a league is done, there is an interbellum of unspecific length where clan leaders can enter their clan. Just keep an eye on the forum Site Announcements and / or Clans when a league is about to finish, or is finished already.
