According to the last few episodes of Star Wars: The Clone Wars (which showed Ahsoka's story arc), it seems that Order 66 happened only a few days after Ahsoka left the Jedi order.
After leaving the Jedi, she went directly to Coruscant Underworld and crashed into mech sisters. She spent one day there maybe.
With the mech sisters, she went to trade spices and got captured by a crime syndicate. The whole thing lasted for a few days.
Then she tried to get help from the Jedi to capture Maul on Mandalore, but they didn't help because Separatists attacked Coruscant (where Dooku would die later).
On Mandalore, she spent a couple of days and captured Maul.
Then, on her way back, Rex received Order 66.
The whole thing seemed to happen within a week.
Is there any official word on this?
How long is the gap (in days) between Ahsoka leaving the Jedi Order and the execution of Order 66?
