The first important timepiece we have from Solo's trailer is that Chewbacca is 190 years old and, according to Wookiepedia, was born in Kashyyyk during the year 200 BBY (before the Battle of Yavin that takes place at the end of A New Hope). Han Solo was born approximately in 29 BBY on the planet Corelia, during the beginning of the fall of the Galactic Republic.


If we do a little math, we can determine that Han is 19 years old when he meets Chewbacca. It was the year 10 BBY, which is nine years after the Empire has taken over the galaxy following the events of The Revenge of the Sith.

What else is going on in 10 BBY? The construction of the Death Star moves to Scarif, the planet where Jyn Erso and Captain Cassian travel to steal the Death Star plans 10 years later in Rogue One, during the year 0 BBY. Also, Jabba the Hutt sends Black Krrsantan to hunt down Obi-Wan Kenobi.

The Solo film begins three years earlier than Han and Chewbacca's first encounter, so we start around year 13 BBY. By end of the movie we should be at around 7 BBY, when Rogue One's Bodhi Rook signs onto the Terrabe Sector Service Academy to become an Imperial pilot before eventually joining the Rebel Alliance.
