This is a simple calendar I made for Mozilla contributors to be aware of when we're doing various channel migrations. Aurora and Beta channel updates come a couple of days after the migration because we need to do some stabilization after migration and before pushing updates to our millions of testers on those channels.

There are some other calendars around but not laid out like I like. One more calendar, so long as they all agree, can only help :-) I've also included links to the releases we've shipped so you can see what we've delivered to hundreds of millions of Firefox users and to the Web over the last few months.
