[Star Wars] "A long time ago, in a galaxy far, far away..."

How long ago was a long time ago?

Given that in-canon works place the age of the Star Wars galaxy at about 13 billion years (give or take), and our Universe is only 13.8 billion years old, and also considering that the oldest known galaxy took 380 million years to form, we can probably say that the setting for Star Wars should be no more than roughly 400 million years in the past, give or take a millenia or two.
