The events of "Part Seven: Dreams and Madness" are placed in 9 ASW4 by "A Certain Point of View" from Star Wars Insider 228. Considering Star Wars: Timelines puts SW4 in 0 BBY, we can infer that 9 ASW4 is equivalent to 9 ABY. Because earlier episodes follow The Book of Boba Fett, which Timelines also dates to 9 ABY, they too are set in the same year. Since "Part Eight: The Jedi, the Witch, and the Warlord" happens soon after Part Seven, it follows that the entirety of Ahsoka happens within a single year.
